## Developing Google Test and Google Mock
@ -101,42 +102,40 @@ To make sure your changes work as intended and don't break existing
functionality, you'll want to compile and run Google Test and GoogleMock's own
tests. For that you can use CMake:
mkdir mybuild
cd mybuild
cmake -Dgtest_build_tests=ON -Dgmock_build_tests=ON ${GTEST_REPO_DIR}
```
mkdir mybuild
cd mybuild
cmake -Dgtest_build_tests=ON -Dgmock_build_tests=ON ${GTEST_REPO_DIR}
```
To choose between building only Google Test or Google Mock, you may modify your
cmake command to be one of each
cmake -Dgtest_build_tests=ON ${GTEST_DIR} # sets up Google Test tests
cmake -Dgmock_build_tests=ON ${GMOCK_DIR} # sets up Google Mock tests
```
cmake -Dgtest_build_tests=ON ${GTEST_DIR} # sets up Google Test tests
cmake -Dgmock_build_tests=ON ${GMOCK_DIR} # sets up Google Mock tests
```
Make sure you have Python installed, as some of Google Test's tests are written
in Python. If the cmake command complains about not being able to find Python
(`Could NOT find PythonInterp (missing: PYTHON_EXECUTABLE)`), try telling it
explicitly where your Python executable can be found:
cmake -DPYTHON_EXECUTABLE=path/to/python ...
```
cmake -DPYTHON_EXECUTABLE=path/to/python ...
```
Next, you can build Google Test and / or Google Mock and all desired tests. On
\*nix, this is usually done by
make
```
make
```
To run the tests, do
make test
```
make test
```
All tests should pass.
### Regenerating Source Files
Some of Google Test's source files are generated from templates (not in the C++
sense) using a script. For example, the file
*googlemock/include/gmock/gmock-generated-actions.h.pump* is used to generate
*gmock-generated-actions.h* in the same directory.
You don't need to worry about regenerating the source files unless you need to
modify them. You would then modify the corresponding `.pump` files and run the
'[pump.py](googlemock/scripts/pump.py)' generator script. See the
[Pump Manual](googlemock/docs/pump_manual.md).

### Announcements:
### Announcements
#### Release 1.10.x
[Release 1.10.x](https://github.com/google/googletest/releases/tag/release-1.10.0)
is now available.
#### Live at Head
GoogleTest now follows the
[Abseil Live at Head philosophy](https://abseil.io/about/philosophy#upgrade-support).
We recommend
[updating to the latest commit in the `main` branch as often as possible](https://github.com/abseil/abseil-cpp/blob/master/FAQ.md#what-is-live-at-head-and-how-do-i-do-it).
We do publish occasional semantic versions, tagged with
`v${major}.${minor}.${patch}` (e.g. `v1.14.0`).
#### Documentation Updates
Our documentation is now live on GitHub Pages at
https://google.github.io/googletest/. We recommend browsing the documentation on
GitHub Pages rather than directly in the repository.
#### Release 1.14.0
[Release 1.14.0](https://github.com/google/googletest/releases/tag/v1.14.0) is
now available.
The 1.14.x branch requires at least C++14.
#### Continuous Integration
We use Google's internal systems for continuous integration. \
GitHub Actions were added for the convenience of open-source contributors. They
are exclusively maintained by the open-source community and not used by the
GoogleTest team.
#### Coming Soon
* Post 1.10.x googletest will follow
[Abseil Live at Head philosophy](https://abseil.io/about/philosophy)
* We are also planning to take a dependency on

## Welcome to **Google Test**, Google's C++ test framework!
## Welcome to **GoogleTest**, Google's C++ test framework!
This repository is a merger of the formerly separate GoogleTest and GoogleMock
projects. These were so closely related that it makes sense to maintain and
release them together.
Please subscribe to the mailing list at googletestframework@googlegroups.com for
questions, discussions, and development.
### Getting Started
### Getting started:
See the [GoogleTest User's Guide](https://google.github.io/googletest/) for
documentation. We recommend starting with the
[GoogleTest Primer](https://google.github.io/googletest/primer.html).
The information for **Google Test** is available in the
[Google Test Primer](googletest/docs/primer.md) documentation.
**Google Mock** is an extension to Google Test for writing and using C++ mock
classes. See the separate [Google Mock documentation](googlemock/README.md).
More detailed documentation for googletest is in its interior
[googletest/README.md](googletest/README.md) file.
More information about building GoogleTest can be found at
[googletest/README.md](googletest/README.md).
## Features

Googletest supports death tests, which verify that your code exits in a
certain way, making it useful for testing error-handling code
* Fatal and non-fatal failures: \
You can specify whether a test failure should be treated as fatal or
non-fatal with Googletest, allowing tests to continue running even if a
failure occurs
* Value-parameterized tests: \
Googletest supports value-parameterized tests, which run multiple times with
different input values, making it useful for testing functions that take
different inputs
* Type-parameterized tests: \
Googletest also supports type-parameterized tests, which run with different
data types, making it useful for testing functions that work with different
data types
* Various options for running tests: \
Googletest provides many options for running tests including running
individual tests, running tests in a specific order and running tests in
parallel

with your projects, but there are some. If you notice any problems on your
platform, please notify
[googletestframework@googlegroups.com](https://groups.google.com/forum/#!forum/googletestframework).
Patches for fixing them are welcome!
### Build Requirements
These are the base requirements to build and use Google Test from a source
package:
* [Bazel](https://bazel.build/) or [CMake](https://cmake.org/). NOTE: Bazel is
the build system that googletest is using internally and tests against.
CMake is community-supported.
* a C++11-standard-compliant compiler

## Why does googletest support `EXPECT_EQ(NULL, ptr)` and `ASSERT_EQ(NULL, ptr)` but not `EXPECT_NE(NULL, ptr)` and `ASSERT_NE(NULL, ptr)`?
## Why does GoogleTest support `EXPECT_EQ(NULL, ptr)` and `ASSERT_EQ(NULL, ptr)` but not `EXPECT_NE(NULL, ptr)` and `ASSERT_NE(NULL, ptr)`?
First of all you can use `EXPECT_NE(nullptr, ptr)` and `ASSERT_NE(nullptr,
ptr)`. This is the preferred syntax in the style guide because nullptr does not
have the type problems that NULL does. Which is why NULL does not work.
First of all, you can use `nullptr` with each of these macros, e.g.
`EXPECT_EQ(ptr, nullptr)`, `EXPECT_NE(ptr, nullptr)`, `ASSERT_EQ(ptr, nullptr)`,
`ASSERT_NE(ptr, nullptr)`. This is the preferred syntax in the style guide
because `nullptr` does not have the type problems that `NULL` does.
Due to some peculiarity of C++, it requires some non-trivial template meta
programming tricks to support using `NULL` as an argument of the `EXPECT_XX()`
and `ASSERT_XX()` macros. Therefore we only do it where it's most needed
(otherwise we make the implementation of googletest harder to maintain and more
(otherwise we make the implementation of GoogleTest harder to maintain and more

The `EXPECT_EQ()` macro takes the *expected* value as its first argument and the
*actual* value as the second. It's reasonable that someone wants to write
`EXPECT_EQ(NULL, some_expression)`, and this indeed was requested several times.
Therefore we implemented it.
Historically, the `EXPECT_EQ()` macro took the *expected* value as its first
argument and the *actual* value as the second, though this argument order is now
discouraged. It was reasonable that someone wanted
to write `EXPECT_EQ(NULL, some_expression)`, and this indeed was requested
several times. Therefore we implemented it.
The need for `EXPECT_NE(NULL, ptr)` isn't nearly as strong. When the assertion
The need for `EXPECT_NE(NULL, ptr)` wasn't nearly as strong. When the assertion
fails, you already know that `ptr` must be `NULL`, so it doesn't add any
information to print `ptr` in this case. That means `EXPECT_TRUE(ptr != NULL)`
works just as well.
If we were to support `EXPECT_NE(NULL, ptr)`, for consistency we'll have to
support `EXPECT_NE(ptr, NULL)` as well, as unlike `EXPECT_EQ`, we don't have a
convention on the order of the two arguments for `EXPECT_NE`. This means using
the template meta programming tricks twice in the implementation, making it even
harder to understand and maintain. We believe the benefit doesn't justify the
cost.

## I got some run-time errors about invalid proto descriptors when using `ProtocolMessageEquals`. Help!
**Note:** `ProtocolMessageEquals` and `ProtocolMessageEquiv` are *deprecated*
now. Please use `EqualsProto`, etc instead.
`ProtocolMessageEquals` and `ProtocolMessageEquiv` were redefined recently and
are now less tolerant of invalid protocol buffer definitions. In particular, if
you have a `foo.proto` that doesn't fully qualify the type of a protocol message
it references (e.g. `message<Bar>` where it should be `message<blah.Bar>`), you
will now get run-time errors like:
```
... descriptor.cc:...] Invalid proto descriptor for file "path/to/foo.proto":
... descriptor.cc:...] blah.MyMessage.my_field: ".Bar" is not defined.
```
If you see this, your `.proto` file is broken and needs to be fixed by making
the types fully qualified. The new definition of `ProtocolMessageEquals` and
`ProtocolMessageEquiv` just happen to reveal your bug.

`htonl()` has some other problems as described in `//util/endian/endian.h`,

does, only without its problems. We suggest you to use `ghtonl()` instead of
`htonl()`, both in your tests and production code.

## The compiler complains "no matching function to call" when I use ASSERT_PRED*. How do I fix it?
## The compiler complains "no matching function to call" when I use `ASSERT_PRED*`. How do I fix it?
If the predicate function you use in `ASSERT_PRED*` or `EXPECT_PRED*` is
overloaded or a template, the compiler will have trouble figuring out which
overloaded version it should use. `ASSERT_PRED_FORMAT*` and
`EXPECT_PRED_FORMAT*` don't have this problem.
If you see this error, you might want to switch to
`(ASSERT|EXPECT)_PRED_FORMAT*`, which will also give you a better failure
message. If, however, that is not an option, you can resolve the problem by
explicitly telling the compiler which version to pick.
For example, suppose you have
```c++
bool IsPositive(int n) {
return n > 0;
}
bool IsPositive(double x) {
return x > 0;
}
```
you will get a compiler error if you write
```c++
EXPECT_PRED1(IsPositive, 5);
```
However, this will work:
```c++
EXPECT_PRED1(static_cast<bool (*)(int)>(IsPositive), 5);
```
(The stuff inside the angled brackets for the `static_cast` operator is the type
of the function pointer for the `int`-version of `IsPositive()`.)
As another example, when you have a template function
```c++
template <typename T>
bool IsNegative(T x) {
return x < 0;
}
```
you can use it in a predicate assertion like this:
```c++
ASSERT_PRED1(IsNegative<int>, -5);
```
Things are more interesting if your template has more than one parameters. The
following won't compile:
```c++
ASSERT_PRED2(GreaterThan<int, int>, 5, 0);
```
as the C++ pre-processor thinks you are giving `ASSERT_PRED2` 4 arguments, which
is one more than expected. The workaround is to wrap the predicate function in
parentheses:
```c++
ASSERT_PRED2((GreaterThan<int, int>), 5, 0);
```

Assertions Reference.

# gMock Cheat Sheet
## Defining a Mock Class
### Mocking a Normal Class {#MockClass}
Given
```cpp
class Foo {
public:
virtual ~Foo();
virtual int GetSize() const = 0;
virtual string Describe(const char* name) = 0;
virtual string Describe(int type) = 0;
virtual bool Process(Bar elem, int count) = 0;
};
```
(note that `~Foo()` **must** be virtual) we can define its mock as
```cpp
#include <gmock/gmock.h>
class MockFoo : public Foo {
public:
MOCK_METHOD(int, GetSize, (), (const, override));
MOCK_METHOD(string, Describe, (const char* name), (override));
MOCK_METHOD(string, Describe, (int type), (override));
MOCK_METHOD(bool, Process, (Bar elem, int count), (override));
};
```
To create a "nice" mock, which ignores all uninteresting calls, a "naggy" mock,
which warns on all uninteresting calls, or a "strict" mock, which treats them as
failures:
```cpp
using ::testing::NiceMock;
using ::testing::NaggyMock;
using ::testing::StrictMock;
NiceMock<MockFoo> nice_foo; // The type is a subclass of MockFoo.
NaggyMock<MockFoo> naggy_foo; // The type is a subclass of MockFoo.
StrictMock<MockFoo> strict_foo; // The type is a subclass of MockFoo.
```
{: .callout .note}
**Note:** A mock object is currently naggy by default. We may make it nice by
default in the future.
### Mocking a Class Template {#MockTemplate}
Class templates can be mocked just like any class.
To mock
```cpp
template <typename Elem>
class StackInterface {
public:
virtual ~StackInterface();
virtual int GetSize() const = 0;
virtual void Push(const Elem& x) = 0;
};
```
(note that all member functions that are mocked, including `~StackInterface()`
**must** be virtual).
```cpp
template <typename Elem>
class MockStack : public StackInterface<Elem> {
public:
MOCK_METHOD(int, GetSize, (), (const, override));
MOCK_METHOD(void, Push, (const Elem& x), (override));
};
```
### Specifying Calling Conventions for Mock Functions
If your mock function doesn't use the default calling convention, you can
specify it by adding `Calltype(convention)` to `MOCK_METHOD`'s 4th parameter.
For example,
```cpp
MOCK_METHOD(bool, Foo, (int n), (Calltype(STDMETHODCALLTYPE)));
MOCK_METHOD(int, Bar, (double x, double y),
(const, Calltype(STDMETHODCALLTYPE)));
```
where `STDMETHODCALLTYPE` is defined by `<objbase.h>` on Windows.
## Using Mocks in Tests {#UsingMocks}
The typical work flow is:
1. Import the gMock names you need to use. All gMock symbols are in the
`testing` namespace unless they are macros or otherwise noted.
2. Create the mock objects.
3. Optionally, set the default actions of the mock objects.
4. Set your expectations on the mock objects (How will they be called? What
will they do?).
5. Exercise code that uses the mock objects; if necessary, check the result
using googletest assertions.
6. When a mock object is destructed, gMock automatically verifies that all
expectations on it have been satisfied.
Here's an example:
```cpp
using ::testing::Return; // #1
TEST(BarTest, DoesThis) {
MockFoo foo; // #2
ON_CALL(foo, GetSize()) // #3
.WillByDefault(Return(1));
// ... other default actions ...
EXPECT_CALL(foo, Describe(5)) // #4
.Times(3)
.WillRepeatedly(Return("Category 5"));
// ... other expectations ...
EXPECT_EQ(MyProductionFunction(&foo), "good"); // #5
} // #6
```
## Setting Default Actions {#OnCall}
gMock has a **built-in default action** for any function that returns `void`,
`bool`, a numeric value, or a pointer. In C++11, it will additionally returns
the default-constructed value, if one exists for the given type.
To customize the default action for functions with return type `T`, use
[`DefaultValue<T>`](reference/mocking.md#DefaultValue). For example:
```cpp
// Sets the default action for return type std::unique_ptr<Buzz> to
// creating a new Buzz every time.
DefaultValue<std::unique_ptr<Buzz>>::SetFactory(
[] { return std::make_unique<Buzz>(AccessLevel::kInternal); });
// When this fires, the default action of MakeBuzz() will run, which
// will return a new Buzz object.
EXPECT_CALL(mock_buzzer_, MakeBuzz("hello")).Times(AnyNumber());
auto buzz1 = mock_buzzer_.MakeBuzz("hello");
auto buzz2 = mock_buzzer_.MakeBuzz("hello");
EXPECT_NE(buzz1, nullptr);
EXPECT_NE(buzz2, nullptr);
EXPECT_NE(buzz1, buzz2);
// Resets the default action for return type std::unique_ptr<Buzz>,
// to avoid interfere with other tests.
DefaultValue<std::unique_ptr<Buzz>>::Clear();
```
To customize the default action for a particular method of a specific mock
object, use [`ON_CALL`](reference/mocking.md#ON_CALL). `ON_CALL` has a similar
syntax to `EXPECT_CALL`, but it is used for setting default behaviors when you
do not require that the mock method is called. See
[Knowing When to Expect](gmock_cook_book.md#UseOnCall) for a more detailed
discussion.
## Setting Expectations {#ExpectCall}
See [`EXPECT_CALL`](reference/mocking.md#EXPECT_CALL) in the Mocking Reference.
## Matchers {#MatcherList}
See the [Matchers Reference](reference/matchers.md).
## Actions {#ActionList}
See the [Actions Reference](reference/actions.md).
## Cardinalities {#CardinalityList}
See the [`Times` clause](reference/mocking.md#EXPECT_CALL.Times) of
`EXPECT_CALL` in the Mocking Reference.
## Expectation Order
By default, expectations can be matched in *any* order. If some or all
expectations must be matched in a given order, you can use the
[`After` clause](reference/mocking.md#EXPECT_CALL.After) or
[`InSequence` clause](reference/mocking.md#EXPECT_CALL.InSequence) of
`EXPECT_CALL`, or use an [`InSequence` object](reference/mocking.md#InSequence).
## Verifying and Resetting a Mock
gMock will verify the expectations on a mock object when it is destructed, or
you can do it earlier:
```cpp
using ::testing::Mock;
...
// Verifies and removes the expectations on mock_obj;
// returns true if and only if successful.
Mock::VerifyAndClearExpectations(&mock_obj);
...
// Verifies and removes the expectations on mock_obj;
// also removes the default actions set by ON_CALL();
// returns true if and only if successful.
Mock::VerifyAndClear(&mock_obj);
```
Do not set new expectations after verifying and clearing a mock after its use.
Setting expectations after code that exercises the mock has undefined behavior.
See [Using Mocks in Tests](gmock_for_dummies.md#using-mocks-in-tests) for more
information.
You can also tell gMock that a mock object can be leaked and doesn't need to be
verified:
```cpp
Mock::AllowLeak(&mock_obj);
```
## Mock Classes
gMock defines a convenient mock class template
```cpp
class MockFunction<R(A1, ..., An)> {
public:
MOCK_METHOD(R, Call, (A1, ..., An));
};
```
See this [recipe](gmock_cook_book.md#UsingCheckPoints) for one application of
it.
## Flags
| Flag | Description |
| :----------------------------- | :---------------------------------------- |
| `--gmock_catch_leaked_mocks=0` | Don't report leaked mock objects as failures. |
| `--gmock_verbose=LEVEL` | Sets the default verbosity level (`info`, `warning`, or `error`) of Google Mock messages. |

(`wchar_t*`, `TCHAR*` in `UNICODE` mode on Windows, or `std::wstring`) is
streamed to an assertion, it will be translated to UTF-8 when printed.
### Basic Assertions
These assertions do basic true/false condition testing.
Fatal assertion | Nonfatal assertion | Verifies
-------------------------- | -------------------------- | --------------------
`ASSERT_TRUE(condition);` | `EXPECT_TRUE(condition);` | `condition` is true
`ASSERT_FALSE(condition);` | `EXPECT_FALSE(condition);` | `condition` is false
Remember, when they fail, `ASSERT_*` yields a fatal failure and returns from the
current function, while `EXPECT_*` yields a nonfatal failure, allowing the
function to continue running. In either case, an assertion failure means its
containing test fails.
**Availability**: Linux, Windows, Mac.
### Binary Comparison
This section describes assertions that compare two values.
Fatal assertion | Nonfatal assertion | Verifies
------------------------ | ------------------------ | --------------
`ASSERT_EQ(val1, val2);` | `EXPECT_EQ(val1, val2);` | `val1 == val2`
`ASSERT_NE(val1, val2);` | `EXPECT_NE(val1, val2);` | `val1 != val2`
`ASSERT_LT(val1, val2);` | `EXPECT_LT(val1, val2);` | `val1 < val2`
`ASSERT_LE(val1, val2);` | `EXPECT_LE(val1, val2);` | `val1 <= val2`
`ASSERT_GT(val1, val2);` | `EXPECT_GT(val1, val2);` | `val1 > val2`
`ASSERT_GE(val1, val2);` | `EXPECT_GE(val1, val2);` | `val1 >= val2`
Value arguments must be comparable by the assertion's comparison operator or
you'll get a compiler error. We used to require the arguments to support the
`<<` operator for streaming to an `ostream`, but this is no longer necessary. If
`<<` is supported, it will be called to print the arguments when the assertion
fails; otherwise googletest will attempt to print them in the best way it can.
For more details and how to customize the printing of the arguments, see the
[documentation](./advanced.md#teaching-googletest-how-to-print-your-values).
These assertions can work with a user-defined type, but only if you define the
corresponding comparison operator (e.g., `==` or `<`). Since this is discouraged
by the Google
[C++ Style Guide](https://google.github.io/styleguide/cppguide.html#Operator_Overloading),
you may need to use `ASSERT_TRUE()` or `EXPECT_TRUE()` to assert the equality of
two objects of a user-defined type.
However, when possible, `ASSERT_EQ(actual, expected)` is preferred to
`ASSERT_TRUE(actual == expected)`, since it tells you `actual` and `expected`'s
values on failure.
Arguments are always evaluated exactly once. Therefore, it's OK for the
arguments to have side effects. However, as with any ordinary C/C++ function,
the arguments' evaluation order is undefined (i.e., the compiler is free to
choose any order), and your code should not depend on any particular argument
evaluation order.
`ASSERT_EQ()` does pointer equality on pointers. If used on two C strings, it
tests if they are in the same memory location, not if they have the same value.
Therefore, if you want to compare C strings (e.g. `const char*`) by value, use
`ASSERT_STREQ()`, which will be described later on. In particular, to assert
that a C string is `NULL`, use `ASSERT_STREQ(c_string, NULL)`. Consider using
`ASSERT_EQ(c_string, nullptr)` if c++11 is supported. To compare two `string`
objects, you should use `ASSERT_EQ`.
When doing pointer comparisons use `*_EQ(ptr, nullptr)` and `*_NE(ptr, nullptr)`
instead of `*_EQ(ptr, NULL)` and `*_NE(ptr, NULL)`. This is because `nullptr` is
typed, while `NULL` is not. See the [FAQ](faq.md) for more details.
If you're working with floating point numbers, you may want to use the floating
point variations of some of these macros in order to avoid problems caused by
rounding. See [Advanced googletest Topics](advanced.md) for details.
Macros in this section work with both narrow and wide string objects (`string`
and `wstring`).
**Availability**: Linux, Windows, Mac.
**Historical note**: Before February 2016 `*_EQ` had a convention of calling it
as `ASSERT_EQ(expected, actual)`, so lots of existing code uses this order. Now
`*_EQ` treats both parameters in the same way.
### String Comparison
The assertions in this group compare two **C strings**. If you want to compare
two `string` objects, use `EXPECT_EQ`, `EXPECT_NE`, and etc instead.
<!-- mdformat off(github rendering does not support multiline tables) -->
| Fatal assertion | Nonfatal assertion | Verifies |
| -------------------------- | ------------------------------ | -------------------------------------------------------- |
| `ASSERT_STREQ(str1,str2);` | `EXPECT_STREQ(str1,str2);` | the two C strings have the same content |
| `ASSERT_STRNE(str1,str2);` | `EXPECT_STRNE(str1,str2);` | the two C strings have different contents |
| `ASSERT_STRCASEEQ(str1,str2);` | `EXPECT_STRCASEEQ(str1,str2);` | the two C strings have the same content, ignoring case |
| `ASSERT_STRCASENE(str1,str2);` | `EXPECT_STRCASENE(str1,str2);` | the two C strings have different contents, ignoring case |
<!-- mdformat on-->
Note that "CASE" in an assertion name means that case is ignored. A `NULL`
pointer and an empty string are considered *different*.
`*STREQ*` and `*STRNE*` also accept wide C strings (`wchar_t*`). If a comparison
of two wide strings fails, their values will be printed as UTF-8 narrow strings.
**Availability**: Linux, Windows, Mac.
**See also**: For more string comparison tricks (substring, prefix, suffix, and
regular expression matching, for example), see [this](advanced.md) in the
Advanced googletest Guide.
GoogleTest provides a collection of assertions for verifying the behavior of
your code in various ways. You can check Boolean conditions, compare values
based on relational operators, verify string values, floating-point values, and
much more. There are even assertions that enable you to verify more complex
states by providing custom predicates. For the complete list of assertions

# Quickstart: Building with Bazel
This tutorial aims to get you up and running with GoogleTest using the Bazel
build system. If you're using GoogleTest for the first time or need a refresher,
we recommend this tutorial as a starting point.
## Prerequisites
To complete this tutorial, you'll need:
* A compatible operating system (e.g. Linux, macOS, Windows).
* A compatible C++ compiler that supports at least C++14.
* [Bazel](https://bazel.build/), the preferred build system used by the
GoogleTest team.
See [Supported Platforms](platforms.md) for more information about platforms
compatible with GoogleTest.
If you don't already have Bazel installed, see the
[Bazel installation guide](https://bazel.build/install).
{: .callout .note} Note: The terminal commands in this tutorial show a Unix
shell prompt, but the commands work on the Windows command line as well.
## Set up a Bazel workspace
A
[Bazel workspace](https://docs.bazel.build/versions/main/build-ref.html#workspace)
is a directory on your filesystem that you use to manage source files for the
software you want to build. Each workspace directory has a text file named
`WORKSPACE` which may be empty, or may contain references to external
dependencies required to build the outputs.
First, create a directory for your workspace:
```
$ mkdir my_workspace && cd my_workspace
```
Next, you’ll create the `WORKSPACE` file to specify dependencies. A common and
recommended way to depend on GoogleTest is to use a
[Bazel external dependency](https://docs.bazel.build/versions/main/external.html)
via the
[`http_archive` rule](https://docs.bazel.build/versions/main/repo/http.html#http_archive).
To do this, in the root directory of your workspace (`my_workspace/`), create a
file named `WORKSPACE` with the following contents:
```
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
name = "com_google_googletest",
urls = ["https://github.com/google/googletest/archive/5ab508a01f9eb089207ee87fd547d290da39d015.zip"],
strip_prefix = "googletest-5ab508a01f9eb089207ee87fd547d290da39d015",
)
```
The above configuration declares a dependency on GoogleTest which is downloaded
as a ZIP archive from GitHub. In the above example,
`5ab508a01f9eb089207ee87fd547d290da39d015` is the Git commit hash of the
GoogleTest version to use; we recommend updating the hash often to point to the
latest version. Use a recent hash on the `main` branch.
Now you're ready to build C++ code that uses GoogleTest.
## Create and run a binary
With your Bazel workspace set up, you can now use GoogleTest code within your
own project.
As an example, create a file named `hello_test.cc` in your `my_workspace`
directory with the following contents:
```cpp
#include <gtest/gtest.h>
// Demonstrate some basic assertions.
TEST(HelloTest, BasicAssertions) {
// Expect two strings not to be equal.
EXPECT_STRNE("hello", "world");
// Expect equality.
EXPECT_EQ(7 * 6, 42);
}
```
GoogleTest provides [assertions](primer.md#assertions) that you use to test the
behavior of your code. The above sample includes the main GoogleTest header file
and demonstrates some basic assertions.
To build the code, create a file named `BUILD` in the same directory with the
following contents:
```
cc_test(
name = "hello_test",
size = "small",
srcs = ["hello_test.cc"],
deps = ["@com_google_googletest//:gtest_main"],
)
```
This `cc_test` rule declares the C++ test binary you want to build, and links to
GoogleTest (`//:gtest_main`) using the prefix you specified in the `WORKSPACE`
file (`@com_google_googletest`). For more information about Bazel `BUILD` files,
see the
[Bazel C++ Tutorial](https://docs.bazel.build/versions/main/tutorial/cpp.html).
{: .callout .note}
NOTE: In the example below, we assume Clang or GCC and set `--cxxopt=-std=c++14`
to ensure that GoogleTest is compiled as C++14 instead of the compiler's default
setting (which could be C++11). For MSVC, the equivalent would be
`--cxxopt=/std:c++14`. See [Supported Platforms](platforms.md) for more details
on supported language versions.
Now you can build and run your test:
<pre>
<strong>my_workspace$ bazel test --cxxopt=-std=c++14 --test_output=all //:hello_test</strong>
INFO: Analyzed target //:hello_test (26 packages loaded, 362 targets configured).

# Quickstart: Building with CMake
This tutorial aims to get you up and running with GoogleTest using CMake. If
you're using GoogleTest for the first time or need a refresher, we recommend
this tutorial as a starting point. If your project uses Bazel, see the
[Quickstart for Bazel](quickstart-bazel.md) instead.
## Prerequisites
To complete this tutorial, you'll need:
* A compatible operating system (e.g. Linux, macOS, Windows).
* A compatible C++ compiler that supports at least C++14.
* [CMake](https://cmake.org/) and a compatible build tool for building the
project.
* Compatible build tools include
[Make](https://www.gnu.org/software/make/),
[Ninja](https://ninja-build.org/), and others - see
[CMake Generators](https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html)
for more information.
See [Supported Platforms](platforms.md) for more information about platforms
compatible with GoogleTest.
If you don't already have CMake installed, see the
[CMake installation guide](https://cmake.org/install).
{: .callout .note}
Note: The terminal commands in this tutorial show a Unix shell prompt, but the
commands work on the Windows command line as well.
## Set up a project
CMake uses a file named `CMakeLists.txt` to configure the build system for a
project. You'll use this file to set up your project and declare a dependency on
GoogleTest.
First, create a directory for your project:
```
$ mkdir my_project && cd my_project
```
Next, you'll create the `CMakeLists.txt` file and declare a dependency on
GoogleTest. There are many ways to express dependencies in the CMake ecosystem;
in this quickstart, you'll use the
[`FetchContent` CMake module](https://cmake.org/cmake/help/latest/module/FetchContent.html).
To do this, in your project directory (`my_project`), create a file named
`CMakeLists.txt` with the following contents:
```cmake
cmake_minimum_required(VERSION 3.14)
project(my_project)
# GoogleTest requires at least C++14
set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
include(FetchContent)
FetchContent_Declare(
googletest
URL https://github.com/google/googletest/archive/03597a01ee50ed33e9dfd640b249b4be3799d395.zip
)
# For Windows: Prevent overriding the parent project's compiler/linker settings
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(googletest)
```
The above configuration declares a dependency on GoogleTest which is downloaded
from GitHub. In the above example, `03597a01ee50ed33e9dfd640b249b4be3799d395` is
the Git commit hash of the GoogleTest version to use; we recommend updating the
hash often to point to the latest version.
For more information about how to create `CMakeLists.txt` files, see the
[CMake Tutorial](https://cmake.org/cmake/help/latest/guide/tutorial/index.html).
## Create and run a binary
With GoogleTest declared as a dependency, you can use GoogleTest code within
your own project.
As an example, create a file named `hello_test.cc` in your `my_project`
directory with the following contents:
```cpp
#include <gtest/gtest.h>
// Demonstrate some basic assertions.
TEST(HelloTest, BasicAssertions) {
// Expect two strings not to be equal.
EXPECT_STRNE("hello", "world");
// Expect equality.
EXPECT_EQ(7 * 6, 42);
}
```
GoogleTest provides [assertions](primer.md#assertions) that you use to test the
behavior of your code. The above sample includes the main GoogleTest header file
and demonstrates some basic assertions.
To build the code, add the following to the end of your `CMakeLists.txt` file:
```cmake
enable_testing()
add_executable(
hello_test
hello_test.cc
)
target_link_libraries(
hello_test
GTest::gtest_main
)
include(GoogleTest)
gtest_discover_tests(hello_test)
```
The above configuration enables testing in CMake, declares the C++ test binary
you want to build (`hello_test`), and links it to GoogleTest (`gtest_main`). The
last two lines enable CMake's test runner to discover the tests included in the
binary, using the
[`GoogleTest` CMake module](https://cmake.org/cmake/help/git-stage/module/GoogleTest.html).
Now you can build and run your test:
<pre>
<strong>my_project$ cmake -S . -B build</strong>
-- The C compiler identification is GNU 10.2.1
-- The CXX compiler identification is GNU 10.2.1
...
-- Build files have been written to: .../my_project/build
<strong>my_project$ cmake --build build</strong>

1/1 Test #1: HelloTest.BasicAssertions ........ Passed 0.00 sec
100% tests passed, 0 tests failed out of 1
Total Test time (real) = 0.01 sec
</pre>
Congratulations! You've successfully built and run a test binary using
GoogleTest.

# Actions Reference
[**Actions**](../gmock_for_dummies.md#actions-what-should-it-do) specify what a
mock function should do when invoked. This page lists the built-in actions
provided by GoogleTest. All actions are defined in the `::testing` namespace.
## Returning a Value
| Action | Description |
| :-------------------------------- | :-------------------------------------------- |
| `Return()` | Return from a `void` mock function. |
| `Return(value)` | Return `value`. If the type of `value` is different to the mock function's return type, `value` is converted to the latter type <i>at the time the expectation is set</i>, not when the action is executed. |
| `ReturnArg<N>()` | Return the `N`-th (0-based) argument. |
| `ReturnNew<T>(a1, ..., ak)` | Return `new T(a1, ..., ak)`; a different object is created each time. |
| `ReturnNull()` | Return a null pointer. |
| `ReturnPointee(ptr)` | Return the value pointed to by `ptr`. |
| `ReturnRef(variable)` | Return a reference to `variable`. |
| `ReturnRefOfCopy(value)` | Return a reference to a copy of `value`; the copy lives as long as the action. |
| `ReturnRoundRobin({a1, ..., ak})` | Each call will return the next `ai` in the list, starting at the beginning when the end of the list is reached. |
## Side Effects
| Action | Description |
| :--------------------------------- | :-------------------------------------- |
| `Assign(&variable, value)` | Assign `value` to variable. |
| `DeleteArg<N>()` | Delete the `N`-th (0-based) argument, which must be a pointer. |
| `SaveArg<N>(pointer)` | Save the `N`-th (0-based) argument to `*pointer`. |
| `SaveArgPointee<N>(pointer)` | Save the value pointed to by the `N`-th (0-based) argument to `*pointer`. |
| `SetArgReferee<N>(value)` | Assign `value` to the variable referenced by the `N`-th (0-based) argument. |
| `SetArgPointee<N>(value)` | Assign `value` to the variable pointed by the `N`-th (0-based) argument. |
| `SetArgumentPointee<N>(value)` | Same as `SetArgPointee<N>(value)`. Deprecated. Will be removed in v1.7.0. |
| `SetArrayArgument<N>(first, last)` | Copies the elements in source range [`first`, `last`) to the array pointed to by the `N`-th (0-based) argument, which can be either a pointer or an iterator. The action does not take ownership of the elements in the source range. |
| `SetErrnoAndReturn(error, value)` | Set `errno` to `error` and return `value`. |
| `Throw(exception)` | Throws the given exception, which can be any copyable value. Available since v1.1.0. |
## Using a Function, Functor, or Lambda as an Action
In the following, by "callable" we mean a free function, `std::function`,
functor, or lambda.
| Action | Description |
| :---------------------------------- | :------------------------------------- |
| `f` | Invoke `f` with the arguments passed to the mock function, where `f` is a callable. |
| `Invoke(f)` | Invoke `f` with the arguments passed to the mock function, where `f` can be a global/static function or a functor. |
| `Invoke(object_pointer, &class::method)` | Invoke the method on the object with the arguments passed to the mock function. |
| `InvokeWithoutArgs(f)` | Invoke `f`, which can be a global/static function or a functor. `f` must take no arguments. |
| `InvokeWithoutArgs(object_pointer, &class::method)` | Invoke the method on the object, which takes no arguments. |
| `InvokeArgument<N>(arg1, arg2, ..., argk)` | Invoke the mock function's `N`-th (0-based) argument, which must be a function or a functor, with the `k` arguments. |
The return value of the invoked function is used as the return value of the
action.
When defining a callable to be used with `Invoke*()`, you can declare any unused
parameters as `Unused`:
```cpp
using ::testing::Invoke;
double Distance(Unused, double x, double y) { return sqrt(x*x + y*y); }
...
EXPECT_CALL(mock, Foo("Hi", _, _)).WillOnce(Invoke(Distance));
```
`Invoke(callback)` and `InvokeWithoutArgs(callback)` take ownership of
`callback`, which must be permanent. The type of `callback` must be a base
callback type instead of a derived one, e.g.
```cpp
BlockingClosure* done = new BlockingClosure;
... Invoke(done) ...; // This won't compile!
Closure* done2 = new BlockingClosure;
... Invoke(done2) ...; // This works.
```
In `InvokeArgument<N>(...)`, if an argument needs to be passed by reference,
wrap it inside `std::ref()`. For example,
```cpp
using ::testing::InvokeArgument;
...
InvokeArgument<2>(5, string("Hi"), std::ref(foo))
```
calls the mock function's #2 argument, passing to it `5` and `string("Hi")` by
value, and `foo` by reference.
## Default Action
| Action | Description |
| :------------ | :----------------------------------------------------- |
| `DoDefault()` | Do the default action (specified by `ON_CALL()` or the built-in one). |
{: .callout .note}
**Note:** due to technical reasons, `DoDefault()` cannot be used inside a
composite action - trying to do so will result in a run-time error.
## Composite Actions
| Action | Description |
| :----------------------------- | :------------------------------------------ |
| `DoAll(a1, a2, ..., an)` | Do all actions `a1` to `an` and return the result of `an` in each invocation. The first `n - 1` sub-actions must return void and will receive a readonly view of the arguments. |
| `IgnoreResult(a)` | Perform action `a` and ignore its result. `a` must not return void. |
| `WithArg<N>(a)` | Pass the `N`-th (0-based) argument of the mock function to action `a` and perform it. |
| `WithArgs<N1, N2, ..., Nk>(a)` | Pass the selected (0-based) arguments of the mock function to action `a` and perform it. |
| `WithoutArgs(a)` | Perform action `a` without any arguments. |
## Defining Actions
| Macro | Description |
| :--------------------------------- | :-------------------------------------- |
| `ACTION(Sum) { return arg0 + arg1; }` | Defines an action `Sum()` to return the sum of the mock function's argument #0 and #1. |
| `ACTION_P(Plus, n) { return arg0 + n; }` | Defines an action `Plus(n)` to return the sum of the mock function's argument #0 and `n`. |
| `ACTION_Pk(Foo, p1, ..., pk) { statements; }` | Defines a parameterized action `Foo(p1, ..., pk)` to execute the given `statements`. |
The `ACTION*` macros cannot be used inside a function or class.

# Assertions Reference
This page lists the assertion macros provided by GoogleTest for verifying code
behavior. To use them, add `#include <gtest/gtest.h>`.
The majority of the macros listed below come as a pair with an `EXPECT_` variant
and an `ASSERT_` variant. Upon failure, `EXPECT_` macros generate nonfatal
failures and allow the current function to continue running, while `ASSERT_`
macros generate fatal failures and abort the current function.
All assertion macros support streaming a custom failure message into them with
the `<<` operator, for example:
```cpp
EXPECT_TRUE(my_condition) << "My condition is not true";
```
Anything that can be streamed to an `ostream` can be streamed to an assertion
macro—in particular, C strings and string objects. If a wide string (`wchar_t*`,
`TCHAR*` in `UNICODE` mode on Windows, or `std::wstring`) is streamed to an
assertion, it will be translated to UTF-8 when printed.
## Explicit Success and Failure {#success-failure}
The assertions in this section generate a success or failure directly instead of
testing a value or expression. These are useful when control flow, rather than a
Boolean expression, determines the test's success or failure, as shown by the
following example:
```c++
switch(expression) {
case 1:
... some checks ...
case 2:
... some other checks ...
default:
FAIL() << "We shouldn't get here.";
}
```
### SUCCEED {#SUCCEED}
`SUCCEED()`
Generates a success. This *does not* make the overall test succeed. A test is
considered successful only if none of its assertions fail during its execution.
The `SUCCEED` assertion is purely documentary and currently doesn't generate any
user-visible output. However, we may add `SUCCEED` messages to GoogleTest output
in the future.
### FAIL {#FAIL}
`FAIL()`
Generates a fatal failure, which returns from the current function.
Can only be used in functions that return `void`. See
[Assertion Placement](../advanced.md#assertion-placement) for more information.
### ADD_FAILURE {#ADD_FAILURE}
`ADD_FAILURE()`
Generates a nonfatal failure, which allows the current function to continue
running.
### ADD_FAILURE_AT {#ADD_FAILURE_AT}
`ADD_FAILURE_AT(`*`file_path`*`,`*`line_number`*`)`
Generates a nonfatal failure at the file and line number specified.
## Generalized Assertion {#generalized}
The following assertion allows [matchers](matchers.md) to be used to verify
values.
### EXPECT_THAT {#EXPECT_THAT}
`EXPECT_THAT(`*`value`*`,`*`matcher`*`)` \
`ASSERT_THAT(`*`value`*`,`*`matcher`*`)`
Verifies that *`value`* matches the [matcher](matchers.md) *`matcher`*.
For example, the following code verifies that the string `value1` starts with
`"Hello"`, `value2` matches a regular expression, and `value3` is between 5 and
10:
```cpp
#include <gmock/gmock.h>
using ::testing::AllOf;
using ::testing::Gt;
using ::testing::Lt;
using ::testing::MatchesRegex;
using ::testing::StartsWith;
...
EXPECT_THAT(value1, StartsWith("Hello"));
EXPECT_THAT(value2, MatchesRegex("Line \\d+"));
ASSERT_THAT(value3, AllOf(Gt(5), Lt(10)));
```
Matchers enable assertions of this form to read like English and generate
informative failure messages. For example, if the above assertion on `value1`
fails, the resulting message will be similar to the following:
```
Value of: value1
Actual: "Hi, world!"
Expected: starts with "Hello"
```
GoogleTest provides a built-in library of matchers—see the
[Matchers Reference](matchers.md). It is also possible to write your own
matchers—see [Writing New Matchers Quickly](../gmock_cook_book.md#NewMatchers).
The use of matchers makes `EXPECT_THAT` a powerful, extensible assertion.
*The idea for this assertion was borrowed from Joe Walnes' Hamcrest project,
which adds `assertThat()` to JUnit.*
## Boolean Conditions {#boolean}
The following assertions test Boolean conditions.
### EXPECT_TRUE {#EXPECT_TRUE}
`EXPECT_TRUE(`*`condition`*`)` \
`ASSERT_TRUE(`*`condition`*`)`
Verifies that *`condition`* is true.
### EXPECT_FALSE {#EXPECT_FALSE}
`EXPECT_FALSE(`*`condition`*`)` \
`ASSERT_FALSE(`*`condition`*`)`
Verifies that *`condition`* is false.
## Binary Comparison {#binary-comparison}
The following assertions compare two values. The value arguments must be
comparable by the assertion's comparison operator, otherwise a compiler error
will result.
If an argument supports the `<<` operator, it will be called to print the
argument when the assertion fails. Otherwise, GoogleTest will attempt to print
them in the best way it can—see
[Teaching GoogleTest How to Print Your Values](../advanced.md#teaching-googletest-how-to-print-your-values).
Arguments are always evaluated exactly once, so it's OK for the arguments to
have side effects. However, the argument evaluation order is undefined and
programs should not depend on any particular argument evaluation order.
These assertions work with both narrow and wide string objects (`string` and
`wstring`).
See also the [Floating-Point Comparison](#floating-point) assertions to compare
floating-point numbers and avoid problems caused by rounding.
### EXPECT_EQ {#EXPECT_EQ}
`EXPECT_EQ(`*`val1`*`,`*`val2`*`)` \
`ASSERT_EQ(`*`val1`*`,`*`val2`*`)`
Verifies that *`val1`*`==`*`val2`*.
Does pointer equality on pointers. If used on two C strings, it tests if they
are in the same memory location, not if they have the same value. Use
[`EXPECT_STREQ`](#EXPECT_STREQ) to compare C strings (e.g. `const char*`) by
value.
When comparing a pointer to `NULL`, use `EXPECT_EQ(`*`ptr`*`, nullptr)` instead
of `EXPECT_EQ(`*`ptr`*`, NULL)`.
### EXPECT_NE {#EXPECT_NE}
`EXPECT_NE(`*`val1`*`,`*`val2`*`)` \
`ASSERT_NE(`*`val1`*`,`*`val2`*`)`
Verifies that *`val1`*`!=`*`val2`*.
Does pointer equality on pointers. If used on two C strings, it tests if they
are in different memory locations, not if they have different values. Use
[`EXPECT_STRNE`](#EXPECT_STRNE) to compare C strings (e.g. `const char*`) by
value.
When comparing a pointer to `NULL`, use `EXPECT_NE(`*`ptr`*`, nullptr)` instead
of `EXPECT_NE(`*`ptr`*`, NULL)`.
### EXPECT_LT {#EXPECT_LT}
`EXPECT_LT(`*`val1`*`,`*`val2`*`)` \
`ASSERT_LT(`*`val1`*`,`*`val2`*`)`
Verifies that *`val1`*`<`*`val2`*.
### EXPECT_LE {#EXPECT_LE}
`EXPECT_LE(`*`val1`*`,`*`val2`*`)` \
`ASSERT_LE(`*`val1`*`,`*`val2`*`)`
Verifies that *`val1`*`<=`*`val2`*.
### EXPECT_GT {#EXPECT_GT}
`EXPECT_GT(`*`val1`*`,`*`val2`*`)` \
`ASSERT_GT(`*`val1`*`,`*`val2`*`)`
Verifies that *`val1`*`>`*`val2`*.
### EXPECT_GE {#EXPECT_GE}
`EXPECT_GE(`*`val1`*`,`*`val2`*`)` \
`ASSERT_GE(`*`val1`*`,`*`val2`*`)`
Verifies that *`val1`*`>=`*`val2`*.
## String Comparison {#c-strings}
The following assertions compare two **C strings**. To compare two `string`
objects, use [`EXPECT_EQ`](#EXPECT_EQ) or [`EXPECT_NE`](#EXPECT_NE) instead.
These assertions also accept wide C strings (`wchar_t*`). If a comparison of two
wide strings fails, their values will be printed as UTF-8 narrow strings.
To compare a C string with `NULL`, use `EXPECT_EQ(`*`c_string`*`, nullptr)` or
`EXPECT_NE(`*`c_string`*`, nullptr)`.
### EXPECT_STREQ {#EXPECT_STREQ}
`EXPECT_STREQ(`*`str1`*`,`*`str2`*`)` \
`ASSERT_STREQ(`*`str1`*`,`*`str2`*`)`
Verifies that the two C strings *`str1`* and *`str2`* have the same contents.
### EXPECT_STRNE {#EXPECT_STRNE}
`EXPECT_STRNE(`*`str1`*`,`*`str2`*`)` \
`ASSERT_STRNE(`*`str1`*`,`*`str2`*`)`
Verifies that the two C strings *`str1`* and *`str2`* have different contents.
### EXPECT_STRCASEEQ {#EXPECT_STRCASEEQ}
`EXPECT_STRCASEEQ(`*`str1`*`,`*`str2`*`)` \
`ASSERT_STRCASEEQ(`*`str1`*`,`*`str2`*`)`
Verifies that the two C strings *`str1`* and *`str2`* have the same contents,
ignoring case.
### EXPECT_STRCASENE {#EXPECT_STRCASENE}
`EXPECT_STRCASENE(`*`str1`*`,`*`str2`*`)` \
`ASSERT_STRCASENE(`*`str1`*`,`*`str2`*`)`
Verifies that the two C strings *`str1`* and *`str2`* have different contents,
ignoring case.
## Floating-Point Comparison {#floating-point}
The following assertions compare two floating-point values.
Due to rounding errors, it is very unlikely that two floating-point values will
match exactly, so `EXPECT_EQ` is not suitable. In general, for floating-point
comparison to make sense, the user needs to carefully choose the error bound.
GoogleTest also provides assertions that use a default error bound based on
Units in the Last Place (ULPs). To learn more about ULPs, see the article
[Comparing Floating Point Numbers](https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/).
### EXPECT_FLOAT_EQ {#EXPECT_FLOAT_EQ}
`EXPECT_FLOAT_EQ(`*`val1`*`,`*`val2`*`)` \
`ASSERT_FLOAT_EQ(`*`val1`*`,`*`val2`*`)`
Verifies that the two `float` values *`val1`* and *`val2`* are approximately
equal, to within 4 ULPs from each other.
### EXPECT_DOUBLE_EQ {#EXPECT_DOUBLE_EQ}
`EXPECT_DOUBLE_EQ(`*`val1`*`,`*`val2`*`)` \
`ASSERT_DOUBLE_EQ(`*`val1`*`,`*`val2`*`)`
Verifies that the two `double` values *`val1`* and *`val2`* are approximately
equal, to within 4 ULPs from each other.
### EXPECT_NEAR {#EXPECT_NEAR}
`EXPECT_NEAR(`*`val1`*`,`*`val2`*`,`*`abs_error`*`)` \
`ASSERT_NEAR(`*`val1`*`,`*`val2`*`,`*`abs_error`*`)`
Verifies that the difference between *`val1`* and *`val2`* does not exceed the
absolute error bound *`abs_error`*.
## Exception Assertions {#exceptions}
The following assertions verify that a piece of code throws, or does not throw,
an exception. Usage requires exceptions to be enabled in the build environment.
Note that the piece of code under test can be a compound statement, for example:
```cpp
EXPECT_NO_THROW({
int n = 5;
DoSomething(&n);
});
```
### EXPECT_THROW {#EXPECT_THROW}
`EXPECT_THROW(`*`statement`*`,`*`exception_type`*`)` \
`ASSERT_THROW(`*`statement`*`,`*`exception_type`*`)`
Verifies that *`statement`* throws an exception of type *`exception_type`*.
### EXPECT_ANY_THROW {#EXPECT_ANY_THROW}
`EXPECT_ANY_THROW(`*`statement`*`)` \
`ASSERT_ANY_THROW(`*`statement`*`)`
Verifies that *`statement`* throws an exception of any type.
### EXPECT_NO_THROW {#EXPECT_NO_THROW}
`EXPECT_NO_THROW(`*`statement`*`)` \
`ASSERT_NO_THROW(`*`statement`*`)`
Verifies that *`statement`* does not throw any exception.
## Predicate Assertions {#predicates}
The following assertions enable more complex predicates to be verified while
printing a more clear failure message than if `EXPECT_TRUE` were used alone.
### EXPECT_PRED* {#EXPECT_PRED}
`EXPECT_PRED1(`*`pred`*`,`*`val1`*`)` \
`EXPECT_PRED2(`*`pred`*`,`*`val1`*`,`*`val2`*`)` \
`EXPECT_PRED3(`*`pred`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`)` \
`EXPECT_PRED4(`*`pred`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`,`*`val4`*`)` \
`EXPECT_PRED5(`*`pred`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`,`*`val4`*`,`*`val5`*`)`
`ASSERT_PRED1(`*`pred`*`,`*`val1`*`)` \
`ASSERT_PRED2(`*`pred`*`,`*`val1`*`,`*`val2`*`)` \
`ASSERT_PRED3(`*`pred`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`)` \
`ASSERT_PRED4(`*`pred`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`,`*`val4`*`)` \
`ASSERT_PRED5(`*`pred`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`,`*`val4`*`,`*`val5`*`)`
Verifies that the predicate *`pred`* returns `true` when passed the given values
as arguments.
The parameter *`pred`* is a function or functor that accepts as many arguments
as the corresponding macro accepts values. If *`pred`* returns `true` for the
given arguments, the assertion succeeds, otherwise the assertion fails.
When the assertion fails, it prints the value of each argument. Arguments are
always evaluated exactly once.
As an example, see the following code:
```cpp
// Returns true if m and n have no common divisors except 1.
bool MutuallyPrime(int m, int n) { ... }
...
const int a = 3;
const int b = 4;
const int c = 10;
...
EXPECT_PRED2(MutuallyPrime, a, b); // Succeeds
EXPECT_PRED2(MutuallyPrime, b, c); // Fails
```
In the above example, the first assertion succeeds, and the second fails with
the following message:
```
MutuallyPrime(b, c) is false, where
b is 4
c is 10
```
Note that if the given predicate is an overloaded function or a function
template, the assertion macro might not be able to determine which version to
use, and it might be necessary to explicitly specify the type of the function.
For example, for a Boolean function `IsPositive()` overloaded to take either a
single `int` or `double` argument, it would be necessary to write one of the
following:
```cpp
EXPECT_PRED1(static_cast<bool (*)(int)>(IsPositive), 5);
EXPECT_PRED1(static_cast<bool (*)(double)>(IsPositive), 3.14);
```
Writing simply `EXPECT_PRED1(IsPositive, 5);` would result in a compiler error.
Similarly, to use a template function, specify the template arguments:
```cpp
template <typename T>
bool IsNegative(T x) {
return x < 0;
}
...
EXPECT_PRED1(IsNegative<int>, -5); // Must specify type for IsNegative
```
If a template has multiple parameters, wrap the predicate in parentheses so the
macro arguments are parsed correctly:
```cpp
ASSERT_PRED2((MyPredicate<int, int>), 5, 0);
```
### EXPECT_PRED_FORMAT* {#EXPECT_PRED_FORMAT}
`EXPECT_PRED_FORMAT1(`*`pred_formatter`*`,`*`val1`*`)` \
`EXPECT_PRED_FORMAT2(`*`pred_formatter`*`,`*`val1`*`,`*`val2`*`)` \
`EXPECT_PRED_FORMAT3(`*`pred_formatter`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`)` \
`EXPECT_PRED_FORMAT4(`*`pred_formatter`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`,`*`val4`*`)`
\
`EXPECT_PRED_FORMAT5(`*`pred_formatter`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`,`*`val4`*`,`*`val5`*`)`
`ASSERT_PRED_FORMAT1(`*`pred_formatter`*`,`*`val1`*`)` \
`ASSERT_PRED_FORMAT2(`*`pred_formatter`*`,`*`val1`*`,`*`val2`*`)` \
`ASSERT_PRED_FORMAT3(`*`pred_formatter`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`)` \
`ASSERT_PRED_FORMAT4(`*`pred_formatter`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`,`*`val4`*`)`
\
`ASSERT_PRED_FORMAT5(`*`pred_formatter`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`,`*`val4`*`,`*`val5`*`)`
Verifies that the predicate *`pred_formatter`* succeeds when passed the given
values as arguments.
The parameter *`pred_formatter`* is a *predicate-formatter*, which is a function
or functor with the signature:
```cpp
testing::AssertionResult PredicateFormatter(const char* expr1,
const char* expr2,
...
const char* exprn,
T1 val1,
T2 val2,
...
Tn valn);
```
where *`val1`*, *`val2`*, ..., *`valn`* are the values of the predicate
arguments, and *`expr1`*, *`expr2`*, ..., *`exprn`* are the corresponding
expressions as they appear in the source code. The types `T1`, `T2`, ..., `Tn`
can be either value types or reference types; if an argument has type `T`, it
can be declared as either `T` or `const T&`, whichever is appropriate. For more
about the return type `testing::AssertionResult`, see
[Using a Function That Returns an AssertionResult](../advanced.md#using-a-function-that-returns-an-assertionresult).
As an example, see the following code:
```cpp
// Returns the smallest prime common divisor of m and n,
// or 1 when m and n are mutually prime.
int SmallestPrimeCommonDivisor(int m, int n) { ... }
// Returns true if m and n have no common divisors except 1.
bool MutuallyPrime(int m, int n) { ... }
// A predicate-formatter for asserting that two integers are mutually prime.
testing::AssertionResult AssertMutuallyPrime(const char* m_expr,
const char* n_expr,
int m,
int n) {
if (MutuallyPrime(m, n)) return testing::AssertionSuccess();
return testing::AssertionFailure() << m_expr << " and " << n_expr
<< " (" << m << " and " << n << ") are not mutually prime, "
<< "as they have a common divisor " << SmallestPrimeCommonDivisor(m, n);
}
...
const int a = 3;
const int b = 4;
const int c = 10;
...
EXPECT_PRED_FORMAT2(AssertMutuallyPrime, a, b); // Succeeds
EXPECT_PRED_FORMAT2(AssertMutuallyPrime, b, c); // Fails
```
In the above example, the final assertion fails and the predicate-formatter
produces the following failure message:
```
b and c (4 and 10) are not mutually prime, as they have a common divisor 2
```
## Windows HRESULT Assertions {#HRESULT}
The following assertions test for `HRESULT` success or failure. For example:
```cpp
CComPtr<IShellDispatch2> shell;
ASSERT_HRESULT_SUCCEEDED(shell.CoCreateInstance(L"Shell.Application"));
CComVariant empty;
ASSERT_HRESULT_SUCCEEDED(shell->ShellExecute(CComBSTR(url), empty, empty, empty, empty));
```
The generated output contains the human-readable error message associated with
the returned `HRESULT` code.
### EXPECT_HRESULT_SUCCEEDED {#EXPECT_HRESULT_SUCCEEDED}
`EXPECT_HRESULT_SUCCEEDED(`*`expression`*`)` \
`ASSERT_HRESULT_SUCCEEDED(`*`expression`*`)`
Verifies that *`expression`* is a success `HRESULT`.
### EXPECT_HRESULT_FAILED {#EXPECT_HRESULT_FAILED}
`EXPECT_HRESULT_FAILED(`*`expression`*`)` \
`ASSERT_HRESULT_FAILED(`*`expression`*`)`
Verifies that *`expression`* is a failure `HRESULT`.
## Death Assertions {#death}
The following assertions verify that a piece of code causes the process to
terminate. For context, see [Death Tests](../advanced.md#death-tests).
These assertions spawn a new process and execute the code under test in that
process. How that happens depends on the platform and the variable
`::testing::GTEST_FLAG(death_test_style)`, which is initialized from the
command-line flag `--gtest_death_test_style`.
* On POSIX systems, `fork()` (or `clone()` on Linux) is used to spawn the
child, after which:
* If the variable's value is `"fast"`, the death test statement is
immediately executed.
* If the variable's value is `"threadsafe"`, the child process re-executes
the unit test binary just as it was originally invoked, but with some
extra flags to cause just the single death test under consideration to
be run.
* On Windows, the child is spawned using the `CreateProcess()` API, and
re-executes the binary to cause just the single death test under
consideration to be run - much like the `"threadsafe"` mode on POSIX.
Other values for the variable are illegal and will cause the death test to fail.
Currently, the flag's default value is
**`"fast"`**.
If the death test statement runs to completion without dying, the child process
will nonetheless terminate, and the assertion fails.
Note that the piece of code under test can be a compound statement, for example:
```cpp
EXPECT_DEATH({
int n = 5;
DoSomething(&n);
}, "Error on line .* of DoSomething()");
```
### EXPECT_DEATH {#EXPECT_DEATH}
`EXPECT_DEATH(`*`statement`*`,`*`matcher`*`)` \
`ASSERT_DEATH(`*`statement`*`,`*`matcher`*`)`
Verifies that *`statement`* causes the process to terminate with a nonzero exit
status and produces `stderr` output that matches *`matcher`*.
The parameter *`matcher`* is either a [matcher](matchers.md) for a `const
std::string&`, or a regular expression (see
[Regular Expression Syntax](../advanced.md#regular-expression-syntax))—a bare
string *`s`* (with no matcher) is treated as
[`ContainsRegex(s)`](matchers.md#string-matchers), **not**
[`Eq(s)`](matchers.md#generic-comparison).
For example, the following code verifies that calling `DoSomething(42)` causes
the process to die with an error message that contains the text `My error`:
```cpp
EXPECT_DEATH(DoSomething(42), "My error");
```
### EXPECT_DEATH_IF_SUPPORTED {#EXPECT_DEATH_IF_SUPPORTED}
`EXPECT_DEATH_IF_SUPPORTED(`*`statement`*`,`*`matcher`*`)` \
`ASSERT_DEATH_IF_SUPPORTED(`*`statement`*`,`*`matcher`*`)`
If death tests are supported, behaves the same as
[`EXPECT_DEATH`](#EXPECT_DEATH). Otherwise, verifies nothing.
### EXPECT_DEBUG_DEATH {#EXPECT_DEBUG_DEATH}
`EXPECT_DEBUG_DEATH(`*`statement`*`,`*`matcher`*`)` \
`ASSERT_DEBUG_DEATH(`*`statement`*`,`*`matcher`*`)`
In debug mode, behaves the same as [`EXPECT_DEATH`](#EXPECT_DEATH). When not in
debug mode (i.e. `NDEBUG` is defined), just executes *`statement`*.
### EXPECT_EXIT {#EXPECT_EXIT}
`EXPECT_EXIT(`*`statement`*`,`*`predicate`*`,`*`matcher`*`)` \
`ASSERT_EXIT(`*`statement`*`,`*`predicate`*`,`*`matcher`*`)`
Verifies that *`statement`* causes the process to terminate with an exit status
that satisfies *`predicate`*, and produces `stderr` output that matches
*`matcher`*.
The parameter *`predicate`* is a function or functor that accepts an `int` exit
status and returns a `bool`. GoogleTest provides two predicates to handle common
cases:
```cpp
// Returns true if the program exited normally with the given exit status code.
::testing::ExitedWithCode(exit_code);
// Returns true if the program was killed by the given signal.
// Not available on Windows.
::testing::KilledBySignal(signal_number);
```
The parameter *`matcher`* is either a [matcher](matchers.md) for a `const
std::string&`, or a regular expression (see
[Regular Expression Syntax](../advanced.md#regular-expression-syntax))—a bare
string *`s`* (with no matcher) is treated as
[`ContainsRegex(s)`](matchers.md#string-matchers), **not**
[`Eq(s)`](matchers.md#generic-comparison).
For example, the following code verifies that calling `NormalExit()` causes the
process to print a message containing the text `Success` to `stderr` and exit
with exit status code 0:
```cpp
EXPECT_EXIT(NormalExit(), testing::ExitedWithCode(0), "Success");
```

# Matchers Reference
A **matcher** matches a *single* argument. You can use it inside `ON_CALL()` or
`EXPECT_CALL()`, or use it to validate a value directly using two macros:
| Macro | Description |
| :----------------------------------- | :------------------------------------ |
| `EXPECT_THAT(actual_value, matcher)` | Asserts that `actual_value` matches `matcher`. |
| `ASSERT_THAT(actual_value, matcher)` | The same as `EXPECT_THAT(actual_value, matcher)`, except that it generates a **fatal** failure. |
{: .callout .warning}
**WARNING:** Equality matching via `EXPECT_THAT(actual_value, expected_value)`
is supported, however note that implicit conversions can cause surprising
results. For example, `EXPECT_THAT(some_bool, "some string")` will compile and
may pass unintentionally.
**BEST PRACTICE:** Prefer to make the comparison explicit via
`EXPECT_THAT(actual_value, Eq(expected_value))` or `EXPECT_EQ(actual_value,
expected_value)`.
Built-in matchers (where `argument` is the function argument, e.g.
`actual_value` in the example above, or when used in the context of
`EXPECT_CALL(mock_object, method(matchers))`, the arguments of `method`) are
divided into several categories. All matchers are defined in the `::testing`
namespace unless otherwise noted.
## Wildcard
Matcher | Description
:-------------------------- | :-----------------------------------------------
`_` | `argument` can be any value of the correct type.
`A<type>()` or `An<type>()` | `argument` can be any value of type `type`.
## Generic Comparison
| Matcher | Description |
| :--------------------- | :-------------------------------------------------- |
| `Eq(value)` or `value` | `argument == value` |
| `Ge(value)` | `argument >= value` |
| `Gt(value)` | `argument > value` |
| `Le(value)` | `argument <= value` |
| `Lt(value)` | `argument < value` |
| `Ne(value)` | `argument != value` |
| `IsFalse()` | `argument` evaluates to `false` in a Boolean context. |
| `IsTrue()` | `argument` evaluates to `true` in a Boolean context. |
| `IsNull()` | `argument` is a `NULL` pointer (raw or smart). |
| `NotNull()` | `argument` is a non-null pointer (raw or smart). |
| `Optional(m)` | `argument` is `optional<>` that contains a value matching `m`. (For testing whether an `optional<>` is set, check for equality with `nullopt`. You may need to use `Eq(nullopt)` if the inner type doesn't have `==`.)|
| `VariantWith<T>(m)` | `argument` is `variant<>` that holds the alternative of type T with a value matching `m`. |
| `Ref(variable)` | `argument` is a reference to `variable`. |
| `TypedEq<type>(value)` | `argument` has type `type` and is equal to `value`. You may need to use this instead of `Eq(value)` when the mock function is overloaded. |
Except `Ref()`, these matchers make a *copy* of `value` in case it's modified or
destructed later. If the compiler complains that `value` doesn't have a public
copy constructor, try wrap it in `std::ref()`, e.g.
`Eq(std::ref(non_copyable_value))`. If you do that, make sure
`non_copyable_value` is not changed afterwards, or the meaning of your matcher
will be changed.
`IsTrue` and `IsFalse` are useful when you need to use a matcher, or for types
that can be explicitly converted to Boolean, but are not implicitly converted to
Boolean. In other cases, you can use the basic
[`EXPECT_TRUE` and `EXPECT_FALSE`](assertions.md#boolean) assertions.
## Floating-Point Matchers {#FpMatchers}
| Matcher | Description |
| :------------------------------- | :--------------------------------- |
| `DoubleEq(a_double)` | `argument` is a `double` value approximately equal to `a_double`, treating two NaNs as unequal. |
| `FloatEq(a_float)` | `argument` is a `float` value approximately equal to `a_float`, treating two NaNs as unequal. |
| `NanSensitiveDoubleEq(a_double)` | `argument` is a `double` value approximately equal to `a_double`, treating two NaNs as equal. |
| `NanSensitiveFloatEq(a_float)` | `argument` is a `float` value approximately equal to `a_float`, treating two NaNs as equal. |
| `IsNan()` | `argument` is any floating-point type with a NaN value. |
The above matchers use ULP-based comparison (the same as used in googletest).
They automatically pick a reasonable error bound based on the absolute value of
the expected value. `DoubleEq()` and `FloatEq()` conform to the IEEE standard,
which requires comparing two NaNs for equality to return false. The
`NanSensitive*` version instead treats two NaNs as equal, which is often what a
user wants.
| Matcher | Description |
| :------------------------------------------------ | :----------------------- |
| `DoubleNear(a_double, max_abs_error)` | `argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
| `FloatNear(a_float, max_abs_error)` | `argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
| `NanSensitiveDoubleNear(a_double, max_abs_error)` | `argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
| `NanSensitiveFloatNear(a_float, max_abs_error)` | `argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
## String Matchers
The `argument` can be either a C string or a C++ string object:
| Matcher | Description |
| :---------------------- | :------------------------------------------------- |
| `ContainsRegex(string)` | `argument` matches the given regular expression. |
| `EndsWith(suffix)` | `argument` ends with string `suffix`. |
| `HasSubstr(string)` | `argument` contains `string` as a sub-string. |
| `IsEmpty()` | `argument` is an empty string. |
| `MatchesRegex(string)` | `argument` matches the given regular expression with the match starting at the first character and ending at the last character. |
| `StartsWith(prefix)` | `argument` starts with string `prefix`. |
| `StrCaseEq(string)` | `argument` is equal to `string`, ignoring case. |
| `StrCaseNe(string)` | `argument` is not equal to `string`, ignoring case. |
| `StrEq(string)` | `argument` is equal to `string`. |
| `StrNe(string)` | `argument` is not equal to `string`. |
| `WhenBase64Unescaped(m)` | `argument` is a base-64 escaped string whose unescaped string matches `m`. The web-safe format from [RFC 4648](https://www.rfc-editor.org/rfc/rfc4648#section-5) is supported. |
`ContainsRegex()` and `MatchesRegex()` take ownership of the `RE` object. They
use the regular expression syntax defined
[here](../advanced.md#regular-expression-syntax). All of these matchers, except
`ContainsRegex()` and `MatchesRegex()` work for wide strings as well.
## Container Matchers
Most STL-style containers support `==`, so you can use `Eq(expected_container)`
or simply `expected_container` to match a container exactly. If you want to
write the elements in-line, match them more flexibly, or get more informative
messages, you can use:
| Matcher | Description |
| :---------------------------------------- | :------------------------------- |
| `BeginEndDistanceIs(m)` | `argument` is a container whose `begin()` and `end()` iterators are separated by a number of increments matching `m`. E.g. `BeginEndDistanceIs(2)` or `BeginEndDistanceIs(Lt(2))`. For containers that define a `size()` method, `SizeIs(m)` may be more efficient. |
| `ContainerEq(container)` | The same as `Eq(container)` except that the failure message also includes which elements are in one container but not the other. |
| `Contains(e)` | `argument` contains an element that matches `e`, which can be either a value or a matcher. |
| `Contains(e).Times(n)` | `argument` contains elements that match `e`, which can be either a value or a matcher, and the number of matches is `n`, which can be either a value or a matcher. Unlike the plain `Contains` and `Each` this allows to check for arbitrary occurrences including testing for absence with `Contains(e).Times(0)`. |
| `Each(e)` | `argument` is a container where *every* element matches `e`, which can be either a value or a matcher. |
| `ElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, where the *i*-th element matches `ei`, which can be a value or a matcher. |
| `ElementsAreArray({e0, e1, ..., en})`, `ElementsAreArray(a_container)`, `ElementsAreArray(begin, end)`, `ElementsAreArray(array)`, or `ElementsAreArray(array, count)` | The same as `ElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
| `IsEmpty()` | `argument` is an empty container (`container.empty()`). |
| `IsSubsetOf({e0, e1, ..., en})`, `IsSubsetOf(a_container)`, `IsSubsetOf(begin, end)`, `IsSubsetOf(array)`, or `IsSubsetOf(array, count)` | `argument` matches `UnorderedElementsAre(x0, x1, ..., xk)` for some subset `{x0, x1, ..., xk}` of the expected matchers. |
| `IsSupersetOf({e0, e1, ..., en})`, `IsSupersetOf(a_container)`, `IsSupersetOf(begin, end)`, `IsSupersetOf(array)`, or `IsSupersetOf(array, count)` | Some subset of `argument` matches `UnorderedElementsAre(`expected matchers`)`. |
| `Pointwise(m, container)`, `Pointwise(m, {e0, e1, ..., en})` | `argument` contains the same number of elements as in `container`, and for all i, (the i-th element in `argument`, the i-th element in `container`) match `m`, which is a matcher on 2-tuples. E.g. `Pointwise(Le(), upper_bounds)` verifies that each element in `argument` doesn't exceed the corresponding element in `upper_bounds`. See more detail below. |
| `SizeIs(m)` | `argument` is a container whose size matches `m`. E.g. `SizeIs(2)` or `SizeIs(Lt(2))`. |
| `UnorderedElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, and under *some* permutation of the elements, each element matches an `ei` (for a different `i`), which can be a value or a matcher. |
| `UnorderedElementsAreArray({e0, e1, ..., en})`, `UnorderedElementsAreArray(a_container)`, `UnorderedElementsAreArray(begin, end)`, `UnorderedElementsAreArray(array)`, or `UnorderedElementsAreArray(array, count)` | The same as `UnorderedElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
| `UnorderedPointwise(m, container)`, `UnorderedPointwise(m, {e0, e1, ..., en})` | Like `Pointwise(m, container)`, but ignores the order of elements. |
| `WhenSorted(m)` | When `argument` is sorted using the `<` operator, it matches container matcher `m`. E.g. `WhenSorted(ElementsAre(1, 2, 3))` verifies that `argument` contains elements 1, 2, and 3, ignoring order. |
| `WhenSortedBy(comparator, m)` | The same as `WhenSorted(m)`, except that the given comparator instead of `<` is used to sort `argument`. E.g. `WhenSortedBy(std::greater(), ElementsAre(3, 2, 1))`. |
**Notes:**
* These matchers can also match:
1. a native array passed by reference (e.g. in `Foo(const int (&a)[5])`),
and
2. an array passed as a pointer and a count (e.g. in `Bar(const T* buffer,
int len)` -- see [Multi-argument Matchers](#MultiArgMatchers)).
* The array being matched may be multi-dimensional (i.e. its elements can be
arrays).
* `m` in `Pointwise(m, ...)` and `UnorderedPointwise(m, ...)` should be a
matcher for `::std::tuple<T, U>` where `T` and `U` are the element type of
the actual container and the expected container, respectively. For example,
to compare two `Foo` containers where `Foo` doesn't support `operator==`,
one might write:
```cpp
MATCHER(FooEq, "") {
return std::get<0>(arg).Equals(std::get<1>(arg));
}
...
EXPECT_THAT(actual_foos, Pointwise(FooEq(), expected_foos));
```
## Member Matchers
| Matcher | Description |
| :------------------------------ | :----------------------------------------- |
| `Field(&class::field, m)` | `argument.field` (or `argument->field` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_. |
| `Field(field_name, &class::field, m)` | The same as the two-parameter version, but provides a better error message. |
| `Key(e)` | `argument.first` matches `e`, which can be either a value or a matcher. E.g. `Contains(Key(Le(5)))` can verify that a `map` contains a key `<= 5`. |
| `Pair(m1, m2)` | `argument` is an `std::pair` whose `first` field matches `m1` and `second` field matches `m2`. |
| `FieldsAre(m...)` | `argument` is a compatible object where each field matches piecewise with the matchers `m...`. A compatible object is any that supports the `std::tuple_size<Obj>`+`get<I>(obj)` protocol. In C++17 and up this also supports types compatible with structured bindings, like aggregates. |
| `Property(&class::property, m)` | `argument.property()` (or `argument->property()` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_. The method `property()` must take no argument and be declared as `const`. |
| `Property(property_name, &class::property, m)` | The same as the two-parameter version, but provides a better error message.
**Notes:**
* You can use `FieldsAre()` to match any type that supports structured
bindings, such as `std::tuple`, `std::pair`, `std::array`, and aggregate
types. For example:
```cpp
std::tuple<int, std::string> my_tuple{7, "hello world"};
EXPECT_THAT(my_tuple, FieldsAre(Ge(0), HasSubstr("hello")));
struct MyStruct {
int value = 42;
std::string greeting = "aloha";
};
MyStruct s;
EXPECT_THAT(s, FieldsAre(42, "aloha"));
```
* Don't use `Property()` against member functions that you do not own, because
taking addresses of functions is fragile and generally not part of the
contract of the function.
## Matching the Result of a Function, Functor, or Callback
| Matcher | Description |
| :--------------- | :------------------------------------------------ |
| `ResultOf(f, m)` | `f(argument)` matches matcher `m`, where `f` is a function or functor. |
| `ResultOf(result_description, f, m)` | The same as the two-parameter version, but provides a better error message.
## Pointer Matchers
| Matcher | Description |
| :------------------------ | :---------------------------------------------- |
| `Address(m)` | the result of `std::addressof(argument)` matches `m`. |
| `Pointee(m)` | `argument` (either a smart pointer or a raw pointer) points to a value that matches matcher `m`. |
| `Pointer(m)` | `argument` (either a smart pointer or a raw pointer) contains a pointer that matches `m`. `m` will match against the raw pointer regardless of the type of `argument`. |
| `WhenDynamicCastTo<T>(m)` | when `argument` is passed through `dynamic_cast<T>()`, it matches matcher `m`. |
## Multi-argument Matchers {#MultiArgMatchers}
Technically, all matchers match a *single* value. A "multi-argument" matcher is
just one that matches a *tuple*. The following matchers can be used to match a
tuple `(x, y)`:
Matcher | Description
:------ | :----------
`Eq()` | `x == y`
`Ge()` | `x >= y`
`Gt()` | `x > y`
`Le()` | `x <= y`
`Lt()` | `x < y`
`Ne()` | `x != y`
You can use the following selectors to pick a subset of the arguments (or
reorder them) to participate in the matching:
| Matcher | Description |
| :------------------------- | :---------------------------------------------- |
| `AllArgs(m)` | Equivalent to `m`. Useful as syntactic sugar in `.With(AllArgs(m))`. |
| `Args<N1, N2, ..., Nk>(m)` | The tuple of the `k` selected (using 0-based indices) arguments matches `m`, e.g. `Args<1, 2>(Eq())`. |
## Composite Matchers
You can make a matcher from one or more other matchers:
| Matcher | Description |
| :------------------------------- | :-------------------------------------- |
| `AllOf(m1, m2, ..., mn)` | `argument` matches all of the matchers `m1` to `mn`. |
| `AllOfArray({m0, m1, ..., mn})`, `AllOfArray(a_container)`, `AllOfArray(begin, end)`, `AllOfArray(array)`, or `AllOfArray(array, count)` | The same as `AllOf()` except that the matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
| `AnyOf(m1, m2, ..., mn)` | `argument` matches at least one of the matchers `m1` to `mn`. |
| `AnyOfArray({m0, m1, ..., mn})`, `AnyOfArray(a_container)`, `AnyOfArray(begin, end)`, `AnyOfArray(array)`, or `AnyOfArray(array, count)` | The same as `AnyOf()` except that the matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
| `Not(m)` | `argument` doesn't match matcher `m`. |
| `Conditional(cond, m1, m2)` | Matches matcher `m1` if `cond` evaluates to true, else matches `m2`.|
## Adapters for Matchers
| Matcher | Description |
| :---------------------- | :------------------------------------ |
| `MatcherCast<T>(m)` | casts matcher `m` to type `Matcher<T>`. |
| `SafeMatcherCast<T>(m)` | [safely casts](../gmock_cook_book.md#SafeMatcherCast) matcher `m` to type `Matcher<T>`. |
| `Truly(predicate)` | `predicate(argument)` returns something considered by C++ to be true, where `predicate` is a function or functor. |
`AddressSatisfies(callback)` and `Truly(callback)` take ownership of `callback`,
which must be a permanent callback.
## Using Matchers as Predicates {#MatchersAsPredicatesCheat}
| Matcher | Description |
| :---------------------------- | :------------------------------------------ |
| `Matches(m)(value)` | evaluates to `true` if `value` matches `m`. You can use `Matches(m)` alone as a unary functor. |
| `ExplainMatchResult(m, value, result_listener)` | evaluates to `true` if `value` matches `m`, explaining the result to `result_listener`. |
| `Value(value, m)` | evaluates to `true` if `value` matches `m`. |
## Defining Matchers
| Macro | Description |
| :----------------------------------- | :------------------------------------ |
| `MATCHER(IsEven, "") { return (arg % 2) == 0; }` | Defines a matcher `IsEven()` to match an even number. |
| `MATCHER_P(IsDivisibleBy, n, "") { *result_listener << "where the remainder is " << (arg % n); return (arg % n) == 0; }` | Defines a matcher `IsDivisibleBy(n)` to match a number divisible by `n`. |
| `MATCHER_P2(IsBetween, a, b, absl::StrCat(negation ? "isn't" : "is", " between ", PrintToString(a), " and ", PrintToString(b))) { return a <= arg && arg <= b; }` | Defines a matcher `IsBetween(a, b)` to match a value in the range [`a`, `b`]. |
**Notes:**
1. The `MATCHER*` macros cannot be used inside a function or class.
2. The matcher body must be *purely functional* (i.e. it cannot have any side
effect, and the result must not depend on anything other than the value
being matched and the matcher parameters).
3. You can use `PrintToString(x)` to convert a value `x` of any type to a
string.
4. You can use `ExplainMatchResult()` in a custom matcher to wrap another
matcher, for example:
```cpp
MATCHER_P(NestedPropertyMatches, matcher, "") {
return ExplainMatchResult(matcher, arg.nested().property(), result_listener);
}
```
5. You can use `DescribeMatcher<>` to describe another matcher. For example:
```cpp
MATCHER_P(XAndYThat, matcher,
"X that " + DescribeMatcher<int>(matcher, negation) +
(negation ? " or" : " and") + " Y that " +
DescribeMatcher<double>(matcher, negation)) {
return ExplainMatchResult(matcher, arg.x(), result_listener) &&
ExplainMatchResult(matcher, arg.y(), result_listener);
}
```

# Mocking Reference
This page lists the facilities provided by GoogleTest for creating and working
with mock objects. To use them, add `#include <gmock/gmock.h>`.
## Macros {#macros}
GoogleTest defines the following macros for working with mocks.
### MOCK_METHOD {#MOCK_METHOD}
`MOCK_METHOD(`*`return_type`*`,`*`method_name`*`, (`*`args...`*`));` \
`MOCK_METHOD(`*`return_type`*`,`*`method_name`*`, (`*`args...`*`),
(`*`specs...`*`));`
Defines a mock method *`method_name`* with arguments `(`*`args...`*`)` and
return type *`return_type`* within a mock class.
The parameters of `MOCK_METHOD` mirror the method declaration. The optional
fourth parameter *`specs...`* is a comma-separated list of qualifiers. The
following qualifiers are accepted:
| Qualifier | Meaning |
| -------------------------- | -------------------------------------------- |
| `const` | Makes the mocked method a `const` method. Required if overriding a `const` method. |
| `override` | Marks the method with `override`. Recommended if overriding a `virtual` method. |
| `noexcept` | Marks the method with `noexcept`. Required if overriding a `noexcept` method. |
| `Calltype(`*`calltype`*`)` | Sets the call type for the method, for example `Calltype(STDMETHODCALLTYPE)`. Useful on Windows. |
| `ref(`*`qualifier`*`)` | Marks the method with the given reference qualifier, for example `ref(&)` or `ref(&&)`. Required if overriding a method that has a reference qualifier. |
Note that commas in arguments prevent `MOCK_METHOD` from parsing the arguments
correctly if they are not appropriately surrounded by parentheses. See the
following example:
```cpp
class MyMock {
public:
// The following 2 lines will not compile due to commas in the arguments:
MOCK_METHOD(std::pair<bool, int>, GetPair, ()); // Error!
MOCK_METHOD(bool, CheckMap, (std::map<int, double>, bool)); // Error!
// One solution - wrap arguments that contain commas in parentheses:
MOCK_METHOD((std::pair<bool, int>), GetPair, ());
MOCK_METHOD(bool, CheckMap, ((std::map<int, double>), bool));
// Another solution - use type aliases:
using BoolAndInt = std::pair<bool, int>;
MOCK_METHOD(BoolAndInt, GetPair, ());
using MapIntDouble = std::map<int, double>;
MOCK_METHOD(bool, CheckMap, (MapIntDouble, bool));
};
```
`MOCK_METHOD` must be used in the `public:` section of a mock class definition,
regardless of whether the method being mocked is `public`, `protected`, or
`private` in the base class.
### EXPECT_CALL {#EXPECT_CALL}
`EXPECT_CALL(`*`mock_object`*`,`*`method_name`*`(`*`matchers...`*`))`
Creates an [expectation](../gmock_for_dummies.md#setting-expectations) that the
method *`method_name`* of the object *`mock_object`* is called with arguments
that match the given matchers *`matchers...`*. `EXPECT_CALL` must precede any
code that exercises the mock object.
The parameter *`matchers...`* is a comma-separated list of
[matchers](../gmock_for_dummies.md#matchers-what-arguments-do-we-expect) that
correspond to each argument of the method *`method_name`*. The expectation will
apply only to calls of *`method_name`* whose arguments match all of the
matchers. If `(`*`matchers...`*`)` is omitted, the expectation behaves as if
each argument's matcher were a [wildcard matcher (`_`)](matchers.md#wildcard).
See the [Matchers Reference](matchers.md) for a list of all built-in matchers.
The following chainable clauses can be used to modify the expectation, and they
must be used in the following order:
```cpp
EXPECT_CALL(mock_object, method_name(matchers...))
.With(multi_argument_matcher) // Can be used at most once
.Times(cardinality) // Can be used at most once
.InSequence(sequences...) // Can be used any number of times
.After(expectations...) // Can be used any number of times
.WillRepeatedly(action) // Can be used any number of times
.WillOnce(action) // Can be used at most once
.RetiresOnSaturation(); // Can be used at most once
```
See details for each modifier clause below.
#### With {#EXPECT_CALL.With}
`.With(`*`multi_argument_matcher`*`)`
Restricts the expectation to apply only to mock function calls whose arguments
as a whole match the multi-argument matcher *`multi_argument_matcher`*.
GoogleTest passes all of the arguments as one tuple into the matcher. The
parameter *`multi_argument_matcher`* must thus be a matcher of type
`Matcher<std::tuple<A1, ..., An>>`, where `A1, ..., An` are the types of the
function arguments.
For example, the following code sets the expectation that
`my_mock.SetPosition()` is called with any two arguments, the first argument
being less than the second:
```cpp
using ::testing::_;
using ::testing::Lt;
...
EXPECT_CALL(my_mock, SetPosition(_, _))
.With(Lt());
```
GoogleTest provides some built-in matchers for 2-tuples, including the `Lt()`
matcher above. See [Multi-argument Matchers](matchers.md#MultiArgMatchers).
The `With` clause can be used at most once on an expectation and must be the
first clause.
#### Times {#EXPECT_CALL.Times}
`.Times(`*`cardinality`*`)`
Specifies how many times the mock function call is expected.
The parameter *`cardinality`* represents the number of expected calls and can be
one of the following, all defined in the `::testing` namespace:
| Cardinality | Meaning |
| ------------------- | --------------------------------------------------- |
| `AnyNumber()` | The function can be called any number of times. |
| `AtLeast(n)` | The function call is expected at least *n* times. |
| `AtMost(n)` | The function call is expected at most *n* times. |
| `Between(m, n)` | The function call is expected between *m* and *n* times, inclusive. |
| `Exactly(n)` or `n` | The function call is expected exactly *n* times. If *n* is 0, the call should never happen. |
If the `Times` clause is omitted, GoogleTest infers the cardinality as follows:
* If neither [`WillOnce`](#EXPECT_CALL.WillOnce) nor
[`WillRepeatedly`](#EXPECT_CALL.WillRepeatedly) are specified, the inferred
cardinality is `Times(1)`.
* If there are *n* `WillOnce` clauses and no `WillRepeatedly` clause, where
*n* >= 1, the inferred cardinality is `Times(n)`.
* If there are *n* `WillOnce` clauses and one `WillRepeatedly` clause, where
*n* >= 0, the inferred cardinality is `Times(AtLeast(n))`.
The `Times` clause can be used at most once on an expectation.
#### InSequence {#EXPECT_CALL.InSequence}
`.InSequence(`*`sequences...`*`)`
Specifies that the mock function call is expected in a certain sequence.
The parameter *`sequences...`* is any number of [`Sequence`](#Sequence) objects.
Expected calls assigned to the same sequence are expected to occur in the order
the expectations are declared.
For example, the following code sets the expectation that the `Reset()` method
of `my_mock` is called before both `GetSize()` and `Describe()`, and `GetSize()`
and `Describe()` can occur in any order relative to each other:
```cpp
using ::testing::Sequence;
Sequence s1, s2;
...
EXPECT_CALL(my_mock, Reset())
.InSequence(s1, s2);
EXPECT_CALL(my_mock, GetSize())
.InSequence(s1);
EXPECT_CALL(my_mock, Describe())
.InSequence(s2);
```
The `InSequence` clause can be used any number of times on an expectation.
See also the [`InSequence` class](#InSequence).
#### After {#EXPECT_CALL.After}
`.After(`*`expectations...`*`)`
Specifies that the mock function call is expected to occur after one or more
other calls.
The parameter *`expectations...`* can be up to five
[`Expectation`](#Expectation) or [`ExpectationSet`](#ExpectationSet) objects.
The mock function call is expected to occur after all of the given expectations.
For example, the following code sets the expectation that the `Describe()`
method of `my_mock` is called only after both `InitX()` and `InitY()` have been
called.
```cpp
using ::testing::Expectation;
...
Expectation init_x = EXPECT_CALL(my_mock, InitX());
Expectation init_y = EXPECT_CALL(my_mock, InitY());
EXPECT_CALL(my_mock, Describe())
.After(init_x, init_y);
```
The `ExpectationSet` object is helpful when the number of prerequisites for an
expectation is large or variable, for example:
```cpp
using ::testing::ExpectationSet;
...
ExpectationSet all_inits;
// Collect all expectations of InitElement() calls
for (int i = 0; i < element_count; i++) {
all_inits += EXPECT_CALL(my_mock, InitElement(i));
}
EXPECT_CALL(my_mock, Describe())
.After(all_inits); // Expect Describe() call after all InitElement() calls
```
The `After` clause can be used any number of times on an expectation.
#### WillOnce {#EXPECT_CALL.WillOnce}
`.WillOnce(`*`action`*`)`
Specifies the mock function's actual behavior when invoked, for a single
matching function call.
The parameter *`action`* represents the
[action](../gmock_for_dummies.md#actions-what-should-it-do) that the function
call will perform. See the [Actions Reference](actions.md) for a list of
built-in actions.
The use of `WillOnce` implicitly sets a cardinality on the expectation when
`Times` is not specified. See [`Times`](#EXPECT_CALL.Times).
Each matching function call will perform the next action in the order declared.
For example, the following code specifies that `my_mock.GetNumber()` is expected
to be called exactly 3 times and will return `1`, `2`, and `3` respectively on
the first, second, and third calls:
```cpp
using ::testing::Return;
...
EXPECT_CALL(my_mock, GetNumber())
.WillOnce(Return(1))
.WillOnce(Return(2))
.WillOnce(Return(3));
```
The `WillOnce` clause can be used any number of times on an expectation. Unlike
`WillRepeatedly`, the action fed to each `WillOnce` call will be called at most
once, so may be a move-only type and/or have an `&&`-qualified call operator.
#### WillRepeatedly {#EXPECT_CALL.WillRepeatedly}
`.WillRepeatedly(`*`action`*`)`
Specifies the mock function's actual behavior when invoked, for all subsequent
matching function calls. Takes effect after the actions specified in the
[`WillOnce`](#EXPECT_CALL.WillOnce) clauses, if any, have been performed.
The parameter *`action`* represents the
[action](../gmock_for_dummies.md#actions-what-should-it-do) that the function
call will perform. See the [Actions Reference](actions.md) for a list of
built-in actions.
The use of `WillRepeatedly` implicitly sets a cardinality on the expectation
when `Times` is not specified. See [`Times`](#EXPECT_CALL.Times).
If any `WillOnce` clauses have been specified, matching function calls will
perform those actions before the action specified by `WillRepeatedly`. See the
following example:
```cpp
using ::testing::Return;
...
EXPECT_CALL(my_mock, GetName())
.WillRepeatedly(Return("John Doe")); // Return "John Doe" on all calls
EXPECT_CALL(my_mock, GetNumber())
.WillOnce(Return(42)) // Return 42 on the first call
.WillRepeatedly(Return(7)); // Return 7 on all subsequent calls
```
The `WillRepeatedly` clause can be used at most once on an expectation.
#### RetiresOnSaturation {#EXPECT_CALL.RetiresOnSaturation}
`.RetiresOnSaturation()`
Indicates that the expectation will no longer be active after the expected
number of matching function calls has been reached.
The `RetiresOnSaturation` clause is only meaningful for expectations with an
upper-bounded cardinality. The expectation will *retire* (no longer match any
function calls) after it has been *saturated* (the upper bound has been
reached). See the following example:
```cpp
using ::testing::_;
using ::testing::AnyNumber;
...
EXPECT_CALL(my_mock, SetNumber(_)) // Expectation 1
.Times(AnyNumber());
EXPECT_CALL(my_mock, SetNumber(7)) // Expectation 2
.Times(2)
.RetiresOnSaturation();
```
In the above example, the first two calls to `my_mock.SetNumber(7)` match
expectation 2, which then becomes inactive and no longer matches any calls. A
third call to `my_mock.SetNumber(7)` would then match expectation 1. Without
`RetiresOnSaturation()` on expectation 2, a third call to `my_mock.SetNumber(7)`
would match expectation 2 again, producing a failure since the limit of 2 calls
was exceeded.
The `RetiresOnSaturation` clause can be used at most once on an expectation and
must be the last clause.
### ON_CALL {#ON_CALL}
`ON_CALL(`*`mock_object`*`,`*`method_name`*`(`*`matchers...`*`))`
Defines what happens when the method *`method_name`* of the object
*`mock_object`* is called with arguments that match the given matchers
*`matchers...`*. Requires a modifier clause to specify the method's behavior.
*Does not* set any expectations that the method will be called.
The parameter *`matchers...`* is a comma-separated list of
[matchers](../gmock_for_dummies.md#matchers-what-arguments-do-we-expect) that
correspond to each argument of the method *`method_name`*. The `ON_CALL`
specification will apply only to calls of *`method_name`* whose arguments match
all of the matchers. If `(`*`matchers...`*`)` is omitted, the behavior is as if
each argument's matcher were a [wildcard matcher (`_`)](matchers.md#wildcard).
See the [Matchers Reference](matchers.md) for a list of all built-in matchers.
The following chainable clauses can be used to set the method's behavior, and
they must be used in the following order:
```cpp
ON_CALL(mock_object, method_name(matchers...))
.With(multi_argument_matcher) // Can be used at most once
.WillByDefault(action); // Required
```
See details for each modifier clause below.
#### With {#ON_CALL.With}
`.With(`*`multi_argument_matcher`*`)`
Restricts the specification to only mock function calls whose arguments as a
whole match the multi-argument matcher *`multi_argument_matcher`*.
GoogleTest passes all of the arguments as one tuple into the matcher. The
parameter *`multi_argument_matcher`* must thus be a matcher of type
`Matcher<std::tuple<A1, ..., An>>`, where `A1, ..., An` are the types of the
function arguments.
For example, the following code sets the default behavior when
`my_mock.SetPosition()` is called with any two arguments, the first argument
being less than the second:
```cpp
using ::testing::_;
using ::testing::Lt;
using ::testing::Return;
...
ON_CALL(my_mock, SetPosition(_, _))
.With(Lt())
.WillByDefault(Return(true));
```
GoogleTest provides some built-in matchers for 2-tuples, including the `Lt()`
matcher above. See [Multi-argument Matchers](matchers.md#MultiArgMatchers).
The `With` clause can be used at most once with each `ON_CALL` statement.
#### WillByDefault {#ON_CALL.WillByDefault}
`.WillByDefault(`*`action`*`)`
Specifies the default behavior of a matching mock function call.
The parameter *`action`* represents the
[action](../gmock_for_dummies.md#actions-what-should-it-do) that the function
call will perform. See the [Actions Reference](actions.md) for a list of
built-in actions.
For example, the following code specifies that by default, a call to
`my_mock.Greet()` will return `"hello"`:
```cpp
using ::testing::Return;
...
ON_CALL(my_mock, Greet())
.WillByDefault(Return("hello"));
```
The action specified by `WillByDefault` is superseded by the actions specified
on a matching `EXPECT_CALL` statement, if any. See the
[`WillOnce`](#EXPECT_CALL.WillOnce) and
[`WillRepeatedly`](#EXPECT_CALL.WillRepeatedly) clauses of `EXPECT_CALL`.
The `WillByDefault` clause must be used exactly once with each `ON_CALL`
statement.
## Classes {#classes}
GoogleTest defines the following classes for working with mocks.
### DefaultValue {#DefaultValue}
`::testing::DefaultValue<T>`
Allows a user to specify the default value for a type `T` that is both copyable
and publicly destructible (i.e. anything that can be used as a function return
type). For mock functions with a return type of `T`, this default value is
returned from function calls that do not specify an action.
Provides the static methods `Set()`, `SetFactory()`, and `Clear()` to manage the
default value:
```cpp
// Sets the default value to be returned. T must be copy constructible.
DefaultValue<T>::Set(value);
// Sets a factory. Will be invoked on demand. T must be move constructible.
T MakeT();
DefaultValue<T>::SetFactory(&MakeT);
// Unsets the default value.
DefaultValue<T>::Clear();
```
### NiceMock {#NiceMock}
`::testing::NiceMock<T>`
Represents a mock object that suppresses warnings on
[uninteresting calls](../gmock_cook_book.md#uninteresting-vs-unexpected). The
template parameter `T` is any mock class, except for another `NiceMock`,
`NaggyMock`, or `StrictMock`.
Usage of `NiceMock<T>` is analogous to usage of `T`. `NiceMock<T>` is a subclass
of `T`, so it can be used wherever an object of type `T` is accepted. In
addition, `NiceMock<T>` can be constructed with any arguments that a constructor
of `T` accepts.
For example, the following code suppresses warnings on the mock `my_mock` of
type `MockClass` if a method other than `DoSomething()` is called:
```cpp
using ::testing::NiceMock;
...
NiceMock<MockClass> my_mock("some", "args");
EXPECT_CALL(my_mock, DoSomething());
... code that uses my_mock ...
```
`NiceMock<T>` only works for mock methods defined using the `MOCK_METHOD` macro
directly in the definition of class `T`. If a mock method is defined in a base
class of `T`, a warning might still be generated.
`NiceMock<T>` might not work correctly if the destructor of `T` is not virtual.
### NaggyMock {#NaggyMock}
`::testing::NaggyMock<T>`
Represents a mock object that generates warnings on
[uninteresting calls](../gmock_cook_book.md#uninteresting-vs-unexpected). The
template parameter `T` is any mock class, except for another `NiceMock`,
`NaggyMock`, or `StrictMock`.
Usage of `NaggyMock<T>` is analogous to usage of `T`. `NaggyMock<T>` is a
subclass of `T`, so it can be used wherever an object of type `T` is accepted.
In addition, `NaggyMock<T>` can be constructed with any arguments that a
constructor of `T` accepts.
For example, the following code generates warnings on the mock `my_mock` of type
`MockClass` if a method other than `DoSomething()` is called:
```cpp
using ::testing::NaggyMock;
...
NaggyMock<MockClass> my_mock("some", "args");
EXPECT_CALL(my_mock, DoSomething());
... code that uses my_mock ...
```
Mock objects of type `T` by default behave the same way as `NaggyMock<T>`.
### StrictMock {#StrictMock}
`::testing::StrictMock<T>`
Represents a mock object that generates test failures on
[uninteresting calls](../gmock_cook_book.md#uninteresting-vs-unexpected). The
template parameter `T` is any mock class, except for another `NiceMock`,
`NaggyMock`, or `StrictMock`.
Usage of `StrictMock<T>` is analogous to usage of `T`. `StrictMock<T>` is a
subclass of `T`, so it can be used wherever an object of type `T` is accepted.
In addition, `StrictMock<T>` can be constructed with any arguments that a
constructor of `T` accepts.
For example, the following code generates a test failure on the mock `my_mock`
of type `MockClass` if a method other than `DoSomething()` is called:
```cpp
using ::testing::StrictMock;
...
StrictMock<MockClass> my_mock("some", "args");
EXPECT_CALL(my_mock, DoSomething());
... code that uses my_mock ...
```
`StrictMock<T>` only works for mock methods defined using the `MOCK_METHOD`
macro directly in the definition of class `T`. If a mock method is defined in a
base class of `T`, a failure might not be generated.
`StrictMock<T>` might not work correctly if the destructor of `T` is not
virtual.
### Sequence {#Sequence}
`::testing::Sequence`
Represents a chronological sequence of expectations. See the
[`InSequence`](#EXPECT_CALL.InSequence) clause of `EXPECT_CALL` for usage.
### InSequence {#InSequence}
`::testing::InSequence`
An object of this type causes all expectations encountered in its scope to be
put in an anonymous sequence.
This allows more convenient expression of multiple expectations in a single
sequence:
```cpp
using ::testing::InSequence;
{
InSequence seq;
// The following are expected to occur in the order declared.
EXPECT_CALL(...);
EXPECT_CALL(...);
...
EXPECT_CALL(...);
}
```
The name of the `InSequence` object does not matter.
### Expectation {#Expectation}
`::testing::Expectation`
Represents a mock function call expectation as created by
[`EXPECT_CALL`](#EXPECT_CALL):
```cpp
using ::testing::Expectation;
Expectation my_expectation = EXPECT_CALL(...);
```
Useful for specifying sequences of expectations; see the
[`After`](#EXPECT_CALL.After) clause of `EXPECT_CALL`.
### ExpectationSet {#ExpectationSet}
`::testing::ExpectationSet`
Represents a set of mock function call expectations.
Use the `+=` operator to add [`Expectation`](#Expectation) objects to the set:
```cpp
using ::testing::ExpectationSet;
ExpectationSet my_expectations;
my_expectations += EXPECT_CALL(...);
```
Useful for specifying sequences of expectations; see the
[`After`](#EXPECT_CALL.After) clause of `EXPECT_CALL`.

## gMock Cheat Sheet
<!-- GOOGLETEST_CM0019 DO NOT DELETE -->
<!-- GOOGLETEST_CM0033 DO NOT DELETE -->
### Defining a Mock Class
#### Mocking a Normal Class {#MockClass}
Given
```cpp
class Foo {
...
virtual ~Foo();
virtual int GetSize() const = 0;
virtual string Describe(const char* name) = 0;
virtual string Describe(int type) = 0;
virtual bool Process(Bar elem, int count) = 0;
};
```
(note that `~Foo()` **must** be virtual) we can define its mock as
```cpp
#include "gmock/gmock.h"
class MockFoo : public Foo {
...
MOCK_METHOD(int, GetSize, (), (const, override));
MOCK_METHOD(string, Describe, (const char* name), (override));
MOCK_METHOD(string, Describe, (int type), (override));
MOCK_METHOD(bool, Process, (Bar elem, int count), (override));
};
```
To create a "nice" mock, which ignores all uninteresting calls, a "naggy" mock,
which warns on all uninteresting calls, or a "strict" mock, which treats them as
failures:
```cpp
using ::testing::NiceMock;
using ::testing::NaggyMock;
using ::testing::StrictMock;
NiceMock<MockFoo> nice_foo; // The type is a subclass of MockFoo.
NaggyMock<MockFoo> naggy_foo; // The type is a subclass of MockFoo.
StrictMock<MockFoo> strict_foo; // The type is a subclass of MockFoo.
```
**Note:** A mock object is currently naggy by default. We may make it nice by
default in the future.
#### Mocking a Class Template {#MockTemplate}
Class templates can be mocked just like any class.
To mock
```cpp
template <typename Elem>
class StackInterface {
...
virtual ~StackInterface();
virtual int GetSize() const = 0;
virtual void Push(const Elem& x) = 0;
};
```
(note that all member functions that are mocked, including `~StackInterface()`
**must** be virtual).
```cpp
template <typename Elem>
class MockStack : public StackInterface<Elem> {
...
MOCK_METHOD(int, GetSize, (), (const, override));
MOCK_METHOD(void, Push, (const Elem& x), (override));
};
```
#### Specifying Calling Conventions for Mock Functions
If your mock function doesn't use the default calling convention, you can
specify it by adding `Calltype(convention)` to `MOCK_METHOD`'s 4th parameter.
For example,
```cpp
MOCK_METHOD(bool, Foo, (int n), (Calltype(STDMETHODCALLTYPE)));
MOCK_METHOD(int, Bar, (double x, double y),
(const, Calltype(STDMETHODCALLTYPE)));
```
where `STDMETHODCALLTYPE` is defined by `<objbase.h>` on Windows.
### Using Mocks in Tests {#UsingMocks}
The typical work flow is:
1. Import the gMock names you need to use. All gMock symbols are in the
`testing` namespace unless they are macros or otherwise noted.
2. Create the mock objects.
3. Optionally, set the default actions of the mock objects.
4. Set your expectations on the mock objects (How will they be called? What
will they do?).
5. Exercise code that uses the mock objects; if necessary, check the result
using googletest assertions.
6. When a mock object is destructed, gMock automatically verifies that all
expectations on it have been satisfied.
Here's an example:
```cpp
using ::testing::Return; // #1
TEST(BarTest, DoesThis) {
MockFoo foo; // #2
ON_CALL(foo, GetSize()) // #3
.WillByDefault(Return(1));
// ... other default actions ...
EXPECT_CALL(foo, Describe(5)) // #4
.Times(3)
.WillRepeatedly(Return("Category 5"));
// ... other expectations ...
EXPECT_EQ("good", MyProductionFunction(&foo)); // #5
} // #6
```
### Setting Default Actions {#OnCall}
gMock has a **built-in default action** for any function that returns `void`,
`bool`, a numeric value, or a pointer. In C++11, it will additionally returns
the default-constructed value, if one exists for the given type.
To customize the default action for functions with return type *`T`*:
```cpp
using ::testing::DefaultValue;
// Sets the default value to be returned. T must be CopyConstructible.
DefaultValue<T>::Set(value);
// Sets a factory. Will be invoked on demand. T must be MoveConstructible.
// T MakeT();
DefaultValue<T>::SetFactory(&MakeT);
// ... use the mocks ...
// Resets the default value.
DefaultValue<T>::Clear();
```
Example usage:
```cpp
// Sets the default action for return type std::unique_ptr<Buzz> to
// creating a new Buzz every time.
DefaultValue<std::unique_ptr<Buzz>>::SetFactory(
[] { return MakeUnique<Buzz>(AccessLevel::kInternal); });
// When this fires, the default action of MakeBuzz() will run, which
// will return a new Buzz object.
EXPECT_CALL(mock_buzzer_, MakeBuzz("hello")).Times(AnyNumber());
auto buzz1 = mock_buzzer_.MakeBuzz("hello");
auto buzz2 = mock_buzzer_.MakeBuzz("hello");
EXPECT_NE(nullptr, buzz1);
EXPECT_NE(nullptr, buzz2);
EXPECT_NE(buzz1, buzz2);
// Resets the default action for return type std::unique_ptr<Buzz>,
// to avoid interfere with other tests.
DefaultValue<std::unique_ptr<Buzz>>::Clear();
```
To customize the default action for a particular method of a specific mock
object, use `ON_CALL()`. `ON_CALL()` has a similar syntax to `EXPECT_CALL()`,
but it is used for setting default behaviors (when you do not require that the
mock method is called). See [here](cook_book.md#UseOnCall) for a more detailed
discussion.
```cpp
ON_CALL(mock-object, method(matchers))
.With(multi-argument-matcher) ?
.WillByDefault(action);
```
### Setting Expectations {#ExpectCall}
`EXPECT_CALL()` sets **expectations** on a mock method (How will it be called?
What will it do?):
```cpp
EXPECT_CALL(mock-object, method (matchers)?)
.With(multi-argument-matcher) ?
.Times(cardinality) ?
.InSequence(sequences) *
.After(expectations) *
.WillOnce(action) *
.WillRepeatedly(action) ?
.RetiresOnSaturation(); ?
```
For each item above, `?` means it can be used at most once, while `*` means it
can be used any number of times.
In order to pass, `EXPECT_CALL` must be used before the calls are actually made.
The `(matchers)` is a comma-separated list of matchers that correspond to each
of the arguments of `method`, and sets the expectation only for calls of
`method` that matches all of the matchers.
If `(matchers)` is omitted, the expectation is the same as if the matchers were
set to anything matchers (for example, `(_, _, _, _)` for a four-arg method).
If `Times()` is omitted, the cardinality is assumed to be:
* `Times(1)` when there is neither `WillOnce()` nor `WillRepeatedly()`;
* `Times(n)` when there are `n` `WillOnce()`s but no `WillRepeatedly()`, where
`n` >= 1; or
* `Times(AtLeast(n))` when there are `n` `WillOnce()`s and a
`WillRepeatedly()`, where `n` >= 0.
A method with no `EXPECT_CALL()` is free to be invoked *any number of times*,
and the default action will be taken each time.
### Matchers {#MatcherList}
<!-- GOOGLETEST_CM0020 DO NOT DELETE -->
A **matcher** matches a *single* argument. You can use it inside `ON_CALL()` or
`EXPECT_CALL()`, or use it to validate a value directly using two macros:
<!-- mdformat off(github rendering does not support multiline tables) -->
| Macro | Description |
| :----------------------------------- | :------------------------------------ |
| `EXPECT_THAT(actual_value, matcher)` | Asserts that `actual_value` matches `matcher`. |
| `ASSERT_THAT(actual_value, matcher)` | The same as `EXPECT_THAT(actual_value, matcher)`, except that it generates a **fatal** failure. |
<!-- mdformat on -->
Built-in matchers (where `argument` is the function argument, e.g.
`actual_value` in the example above, or when used in the context of
`EXPECT_CALL(mock_object, method(matchers))`, the arguments of `method`) are
divided into several categories:
#### Wildcard
Matcher | Description
:-------------------------- | :-----------------------------------------------
`_` | `argument` can be any value of the correct type.
`A<type>()` or `An<type>()` | `argument` can be any value of type `type`.
#### Generic Comparison
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :--------------------- | :-------------------------------------------------- |
| `Eq(value)` or `value` | `argument == value` |
| `Ge(value)` | `argument >= value` |
| `Gt(value)` | `argument > value` |
| `Le(value)` | `argument <= value` |
| `Lt(value)` | `argument < value` |
| `Ne(value)` | `argument != value` |
| `IsFalse()` | `argument` evaluates to `false` in a Boolean context. |
| `IsTrue()` | `argument` evaluates to `true` in a Boolean context. |
| `IsNull()` | `argument` is a `NULL` pointer (raw or smart). |
| `NotNull()` | `argument` is a non-null pointer (raw or smart). |
| `Optional(m)` | `argument` is `optional<>` that contains a value matching `m`. (For testing whether an `optional<>` is set, check for equality with `nullopt`. You may need to use `Eq(nullopt)` if the inner type doesn't have `==`.)|
| `VariantWith<T>(m)` | `argument` is `variant<>` that holds the alternative of type T with a value matching `m`. |
| `Ref(variable)` | `argument` is a reference to `variable`. |
| `TypedEq<type>(value)` | `argument` has type `type` and is equal to `value`. You may need to use this instead of `Eq(value)` when the mock function is overloaded. |
<!-- mdformat on -->
Except `Ref()`, these matchers make a *copy* of `value` in case it's modified or
destructed later. If the compiler complains that `value` doesn't have a public
copy constructor, try wrap it in `ByRef()`, e.g.
`Eq(ByRef(non_copyable_value))`. If you do that, make sure `non_copyable_value`
is not changed afterwards, or the meaning of your matcher will be changed.
`IsTrue` and `IsFalse` are useful when you need to use a matcher, or for types
that can be explicitly converted to Boolean, but are not implicitly converted to
Boolean. In other cases, you can use the basic
[`EXPECT_TRUE` and `EXPECT_FALSE`](../../googletest/docs/primer#basic-assertions)
assertions.
#### Floating-Point Matchers {#FpMatchers}
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :------------------------------- | :--------------------------------- |
| `DoubleEq(a_double)` | `argument` is a `double` value approximately equal to `a_double`, treating two NaNs as unequal. |
| `FloatEq(a_float)` | `argument` is a `float` value approximately equal to `a_float`, treating two NaNs as unequal. |
| `NanSensitiveDoubleEq(a_double)` | `argument` is a `double` value approximately equal to `a_double`, treating two NaNs as equal. |
| `NanSensitiveFloatEq(a_float)` | `argument` is a `float` value approximately equal to `a_float`, treating two NaNs as equal. |
| `IsNan()` | `argument` is any floating-point type with a NaN value. |
<!-- mdformat on -->
The above matchers use ULP-based comparison (the same as used in googletest).
They automatically pick a reasonable error bound based on the absolute value of
the expected value. `DoubleEq()` and `FloatEq()` conform to the IEEE standard,
which requires comparing two NaNs for equality to return false. The
`NanSensitive*` version instead treats two NaNs as equal, which is often what a
user wants.
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :------------------------------------------------ | :----------------------- |
| `DoubleNear(a_double, max_abs_error)` | `argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
| `FloatNear(a_float, max_abs_error)` | `argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
| `NanSensitiveDoubleNear(a_double, max_abs_error)` | `argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
| `NanSensitiveFloatNear(a_float, max_abs_error)` | `argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
<!-- mdformat on -->
#### String Matchers
The `argument` can be either a C string or a C++ string object:
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :---------------------- | :------------------------------------------------- |
| `ContainsRegex(string)` | `argument` matches the given regular expression. |
| `EndsWith(suffix)` | `argument` ends with string `suffix`. |
| `HasSubstr(string)` | `argument` contains `string` as a sub-string. |
| `MatchesRegex(string)` | `argument` matches the given regular expression with the match starting at the first character and ending at the last character. |
| `StartsWith(prefix)` | `argument` starts with string `prefix`. |
| `StrCaseEq(string)` | `argument` is equal to `string`, ignoring case. |
| `StrCaseNe(string)` | `argument` is not equal to `string`, ignoring case. |
| `StrEq(string)` | `argument` is equal to `string`. |
| `StrNe(string)` | `argument` is not equal to `string`. |
<!-- mdformat on -->
`ContainsRegex()` and `MatchesRegex()` take ownership of the `RE` object. They
use the regular expression syntax defined
[here](../../googletest/docs/advanced.md#regular-expression-syntax). All of
these matchers, except `ContainsRegex()` and `MatchesRegex()` work for wide
strings as well.
#### Container Matchers
Most STL-style containers support `==`, so you can use `Eq(expected_container)`
or simply `expected_container` to match a container exactly. If you want to
write the elements in-line, match them more flexibly, or get more informative
messages, you can use:
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :---------------------------------------- | :------------------------------- |
| `BeginEndDistanceIs(m)` | `argument` is a container whose `begin()` and `end()` iterators are separated by a number of increments matching `m`. E.g. `BeginEndDistanceIs(2)` or `BeginEndDistanceIs(Lt(2))`. For containers that define a `size()` method, `SizeIs(m)` may be more efficient. |
| `ContainerEq(container)` | The same as `Eq(container)` except that the failure message also includes which elements are in one container but not the other. |
| `Contains(e)` | `argument` contains an element that matches `e`, which can be either a value or a matcher. |
| `Each(e)` | `argument` is a container where *every* element matches `e`, which can be either a value or a matcher. |
| `ElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, where the *i*-th element matches `ei`, which can be a value or a matcher. |
| `ElementsAreArray({e0, e1, ..., en})`, `ElementsAreArray(a_container)`, `ElementsAreArray(begin, end)`, `ElementsAreArray(array)`, or `ElementsAreArray(array, count)` | The same as `ElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
| `IsEmpty()` | `argument` is an empty container (`container.empty()`). |
| `IsSubsetOf({e0, e1, ..., en})`, `IsSubsetOf(a_container)`, `IsSubsetOf(begin, end)`, `IsSubsetOf(array)`, or `IsSubsetOf(array, count)` | `argument` matches `UnorderedElementsAre(x0, x1, ..., xk)` for some subset `{x0, x1, ..., xk}` of the expected matchers. |
| `IsSupersetOf({e0, e1, ..., en})`, `IsSupersetOf(a_container)`, `IsSupersetOf(begin, end)`, `IsSupersetOf(array)`, or `IsSupersetOf(array, count)` | Some subset of `argument` matches `UnorderedElementsAre(`expected matchers`)`. |
| `Pointwise(m, container)`, `Pointwise(m, {e0, e1, ..., en})` | `argument` contains the same number of elements as in `container`, and for all i, (the i-th element in `argument`, the i-th element in `container`) match `m`, which is a matcher on 2-tuples. E.g. `Pointwise(Le(), upper_bounds)` verifies that each element in `argument` doesn't exceed the corresponding element in `upper_bounds`. See more detail below. |
| `SizeIs(m)` | `argument` is a container whose size matches `m`. E.g. `SizeIs(2)` or `SizeIs(Lt(2))`. |
| `UnorderedElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, and under *some* permutation of the elements, each element matches an `ei` (for a different `i`), which can be a value or a matcher. |
| `UnorderedElementsAreArray({e0, e1, ..., en})`, `UnorderedElementsAreArray(a_container)`, `UnorderedElementsAreArray(begin, end)`, `UnorderedElementsAreArray(array)`, or `UnorderedElementsAreArray(array, count)` | The same as `UnorderedElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
| `UnorderedPointwise(m, container)`, `UnorderedPointwise(m, {e0, e1, ..., en})` | Like `Pointwise(m, container)`, but ignores the order of elements. |
| `WhenSorted(m)` | When `argument` is sorted using the `<` operator, it matches container matcher `m`. E.g. `WhenSorted(ElementsAre(1, 2, 3))` verifies that `argument` contains elements 1, 2, and 3, ignoring order. |
| `WhenSortedBy(comparator, m)` | The same as `WhenSorted(m)`, except that the given comparator instead of `<` is used to sort `argument`. E.g. `WhenSortedBy(std::greater(), ElementsAre(3, 2, 1))`. |
<!-- mdformat on -->
**Notes:**
* These matchers can also match:
1. a native array passed by reference (e.g. in `Foo(const int (&a)[5])`),
and
2. an array passed as a pointer and a count (e.g. in `Bar(const T* buffer,
int len)` -- see [Multi-argument Matchers](#MultiArgMatchers)).
* The array being matched may be multi-dimensional (i.e. its elements can be
arrays).
* `m` in `Pointwise(m, ...)` should be a matcher for `::std::tuple<T, U>`
where `T` and `U` are the element type of the actual container and the
expected container, respectively. For example, to compare two `Foo`
containers where `Foo` doesn't support `operator==`, one might write:
```cpp
using ::std::get;
MATCHER(FooEq, "") {
return std::get<0>(arg).Equals(std::get<1>(arg));
}
...
EXPECT_THAT(actual_foos, Pointwise(FooEq(), expected_foos));
```
#### Member Matchers
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :------------------------------ | :----------------------------------------- |
| `Field(&class::field, m)` | `argument.field` (or `argument->field` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_. |
| `Key(e)` | `argument.first` matches `e`, which can be either a value or a matcher. E.g. `Contains(Key(Le(5)))` can verify that a `map` contains a key `<= 5`. |
| `Pair(m1, m2)` | `argument` is an `std::pair` whose `first` field matches `m1` and `second` field matches `m2`. |
| `Property(&class::property, m)` | `argument.property()` (or `argument->property()` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_. |
<!-- mdformat on -->
#### Matching the Result of a Function, Functor, or Callback
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :--------------- | :------------------------------------------------ |
| `ResultOf(f, m)` | `f(argument)` matches matcher `m`, where `f` is a function or functor. |
<!-- mdformat on -->
#### Pointer Matchers
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :------------------------ | :---------------------------------------------- |
| `Pointee(m)` | `argument` (either a smart pointer or a raw pointer) points to a value that matches matcher `m`. |
| `WhenDynamicCastTo<T>(m)` | when `argument` is passed through `dynamic_cast<T>()`, it matches matcher `m`. |
<!-- mdformat on -->
<!-- GOOGLETEST_CM0026 DO NOT DELETE -->
<!-- GOOGLETEST_CM0027 DO NOT DELETE -->
#### Multi-argument Matchers {#MultiArgMatchers}
Technically, all matchers match a *single* value. A "multi-argument" matcher is
just one that matches a *tuple*. The following matchers can be used to match a
tuple `(x, y)`:
Matcher | Description
:------ | :----------
`Eq()` | `x == y`
`Ge()` | `x >= y`
`Gt()` | `x > y`
`Le()` | `x <= y`
`Lt()` | `x < y`
`Ne()` | `x != y`
You can use the following selectors to pick a subset of the arguments (or
reorder them) to participate in the matching:
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :------------------------- | :---------------------------------------------- |
| `AllArgs(m)` | Equivalent to `m`. Useful as syntactic sugar in `.With(AllArgs(m))`. |
| `Args<N1, N2, ..., Nk>(m)` | The tuple of the `k` selected (using 0-based indices) arguments matches `m`, e.g. `Args<1, 2>(Eq())`. |
<!-- mdformat on -->
#### Composite Matchers
You can make a matcher from one or more other matchers:
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :------------------------------- | :-------------------------------------- |
| `AllOf(m1, m2, ..., mn)` | `argument` matches all of the matchers `m1` to `mn`. |
| `AllOfArray({m0, m1, ..., mn})`, `AllOfArray(a_container)`, `AllOfArray(begin, end)`, `AllOfArray(array)`, or `AllOfArray(array, count)` | The same as `AllOf()` except that the matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
| `AnyOf(m1, m2, ..., mn)` | `argument` matches at least one of the matchers `m1` to `mn`. |
| `AnyOfArray({m0, m1, ..., mn})`, `AnyOfArray(a_container)`, `AnyOfArray(begin, end)`, `AnyOfArray(array)`, or `AnyOfArray(array, count)` | The same as `AnyOf()` except that the matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
| `Not(m)` | `argument` doesn't match matcher `m`. |
<!-- mdformat on -->
<!-- GOOGLETEST_CM0028 DO NOT DELETE -->
#### Adapters for Matchers
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :---------------------- | :------------------------------------ |
| `MatcherCast<T>(m)` | casts matcher `m` to type `Matcher<T>`. |
| `SafeMatcherCast<T>(m)` | [safely casts](cook_book.md#casting-matchers) matcher `m` to type `Matcher<T>`. |
| `Truly(predicate)` | `predicate(argument)` returns something considered by C++ to be true, where `predicate` is a function or functor. |
<!-- mdformat on -->
`AddressSatisfies(callback)` and `Truly(callback)` take ownership of `callback`,
which must be a permanent callback.
#### Using Matchers as Predicates {#MatchersAsPredicatesCheat}
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :---------------------------- | :------------------------------------------ |
| `Matches(m)(value)` | evaluates to `true` if `value` matches `m`. You can use `Matches(m)` alone as a unary functor. |
| `ExplainMatchResult(m, value, result_listener)` | evaluates to `true` if `value` matches `m`, explaining the result to `result_listener`. |
| `Value(value, m)` | evaluates to `true` if `value` matches `m`. |
<!-- mdformat on -->
#### Defining Matchers
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :----------------------------------- | :------------------------------------ |
| `MATCHER(IsEven, "") { return (arg % 2) == 0; }` | Defines a matcher `IsEven()` to match an even number. |
| `MATCHER_P(IsDivisibleBy, n, "") { *result_listener << "where the remainder is " << (arg % n); return (arg % n) == 0; }` | Defines a matcher `IsDivisibleBy(n)` to match a number divisible by `n`. |
| `MATCHER_P2(IsBetween, a, b, std::string(negation ? "isn't" : "is") + " between " + PrintToString(a) + " and " + PrintToString(b)) { return a <= arg && arg <= b; }` | Defines a matcher `IsBetween(a, b)` to match a value in the range [`a`, `b`]. |
<!-- mdformat on -->
**Notes:**
1. The `MATCHER*` macros cannot be used inside a function or class.
2. The matcher body must be *purely functional* (i.e. it cannot have any side
effect, and the result must not depend on anything other than the value
being matched and the matcher parameters).
3. You can use `PrintToString(x)` to convert a value `x` of any type to a
string.
### Actions {#ActionList}
**Actions** specify what a mock function should do when invoked.
#### Returning a Value
<!-- mdformat off(no multiline tables) -->
| | |
| :-------------------------------- | :-------------------------------------------- |
| `Return()` | Return from a `void` mock function. |
| `Return(value)` | Return `value`. If the type of `value` is different to the mock function's return type, `value` is converted to the latter type <i>at the time the expectation is set</i>, not when the action is executed. |
| `ReturnArg<N>()` | Return the `N`-th (0-based) argument. |
| `ReturnNew<T>(a1, ..., ak)` | Return `new T(a1, ..., ak)`; a different object is created each time. |
| `ReturnNull()` | Return a null pointer. |
| `ReturnPointee(ptr)` | Return the value pointed to by `ptr`. |
| `ReturnRef(variable)` | Return a reference to `variable`. |
| `ReturnRefOfCopy(value)` | Return a reference to a copy of `value`; the copy lives as long as the action. |
| `ReturnRoundRobin({a1, ..., ak})` | Each call will return the next `ai` in the list, starting at the beginning when the end of the list is reached. |
<!-- mdformat on -->
#### Side Effects
<!-- mdformat off(no multiline tables) -->
| | |
| :--------------------------------- | :-------------------------------------- |
| `Assign(&variable, value)` | Assign `value` to variable. |
| `DeleteArg<N>()` | Delete the `N`-th (0-based) argument, which must be a pointer. |
| `SaveArg<N>(pointer)` | Save the `N`-th (0-based) argument to `*pointer`. |
| `SaveArgPointee<N>(pointer)` | Save the value pointed to by the `N`-th (0-based) argument to `*pointer`. |
| `SetArgReferee<N>(value)` | Assign value to the variable referenced by the `N`-th (0-based) argument. |
| `SetArgPointee<N>(value)` | Assign `value` to the variable pointed by the `N`-th (0-based) argument. |
| `SetArgumentPointee<N>(value)` | Same as `SetArgPointee<N>(value)`. Deprecated. Will be removed in v1.7.0. |
| `SetArrayArgument<N>(first, last)` | Copies the elements in source range [`first`, `last`) to the array pointed to by the `N`-th (0-based) argument, which can be either a pointer or an iterator. The action does not take ownership of the elements in the source range. |
| `SetErrnoAndReturn(error, value)` | Set `errno` to `error` and return `value`. |
| `Throw(exception)` | Throws the given exception, which can be any copyable value. Available since v1.1.0. |
<!-- mdformat on -->
#### Using a Function, Functor, or Lambda as an Action
In the following, by "callable" we mean a free function, `std::function`,
functor, or lambda.
<!-- mdformat off(no multiline tables) -->
| | |
| :---------------------------------- | :------------------------------------- |
| `f` | Invoke f with the arguments passed to the mock function, where f is a callable. |
| `Invoke(f)` | Invoke `f` with the arguments passed to the mock function, where `f` can be a global/static function or a functor. |
| `Invoke(object_pointer, &class::method)` | Invoke the method on the object with the arguments passed to the mock function. |
| `InvokeWithoutArgs(f)` | Invoke `f`, which can be a global/static function or a functor. `f` must take no arguments. |
| `InvokeWithoutArgs(object_pointer, &class::method)` | Invoke the method on the object, which takes no arguments. |
| `InvokeArgument<N>(arg1, arg2, ..., argk)` | Invoke the mock function's `N`-th (0-based) argument, which must be a function or a functor, with the `k` arguments. |
<!-- mdformat on -->
The return value of the invoked function is used as the return value of the
action.
When defining a callable to be used with `Invoke*()`, you can declare any unused
parameters as `Unused`:
```cpp
using ::testing::Invoke;
double Distance(Unused, double x, double y) { return sqrt(x*x + y*y); }
...
EXPECT_CALL(mock, Foo("Hi", _, _)).WillOnce(Invoke(Distance));
```
`Invoke(callback)` and `InvokeWithoutArgs(callback)` take ownership of
`callback`, which must be permanent. The type of `callback` must be a base
callback type instead of a derived one, e.g.
```cpp
BlockingClosure* done = new BlockingClosure;
... Invoke(done) ...; // This won't compile!
Closure* done2 = new BlockingClosure;
... Invoke(done2) ...; // This works.
```
In `InvokeArgument<N>(...)`, if an argument needs to be passed by reference,
wrap it inside `ByRef()`. For example,
```cpp
using ::testing::ByRef;
using ::testing::InvokeArgument;
...
InvokeArgument<2>(5, string("Hi"), ByRef(foo))
```
calls the mock function's #2 argument, passing to it `5` and `string("Hi")` by
value, and `foo` by reference.
#### Default Action
<!-- mdformat off(no multiline tables) -->
| Matcher | Description |
| :------------ | :----------------------------------------------------- |
| `DoDefault()` | Do the default action (specified by `ON_CALL()` or the built-in one). |
<!-- mdformat on -->
**Note:** due to technical reasons, `DoDefault()` cannot be used inside a
composite action - trying to do so will result in a run-time error.
<!-- GOOGLETEST_CM0032 DO NOT DELETE -->
#### Composite Actions
<!-- mdformat off(no multiline tables) -->
| | |
| :----------------------------- | :------------------------------------------ |
| `DoAll(a1, a2, ..., an)` | Do all actions `a1` to `an` and return the result of `an` in each invocation. The first `n - 1` sub-actions must return void. |
| `IgnoreResult(a)` | Perform action `a` and ignore its result. `a` must not return void. |
| `WithArg<N>(a)` | Pass the `N`-th (0-based) argument of the mock function to action `a` and perform it. |
| `WithArgs<N1, N2, ..., Nk>(a)` | Pass the selected (0-based) arguments of the mock function to action `a` and perform it. |
| `WithoutArgs(a)` | Perform action `a` without any arguments. |
<!-- mdformat on -->
#### Defining Actions
<!-- mdformat off(no multiline tables) -->
| | |
| :--------------------------------- | :-------------------------------------- |
| `ACTION(Sum) { return arg0 + arg1; }` | Defines an action `Sum()` to return the sum of the mock function's argument #0 and #1. |
| `ACTION_P(Plus, n) { return arg0 + n; }` | Defines an action `Plus(n)` to return the sum of the mock function's argument #0 and `n`. |
| `ACTION_Pk(Foo, p1, ..., pk) { statements; }` | Defines a parameterized action `Foo(p1, ..., pk)` to execute the given `statements`. |
<!-- mdformat on -->
The `ACTION*` macros cannot be used inside a function or class.
### Cardinalities {#CardinalityList}
These are used in `Times()` to specify how many times a mock function will be
called:
<!-- mdformat off(no multiline tables) -->
| | |
| :---------------- | :----------------------------------------------------- |
| `AnyNumber()` | The function can be called any number of times. |
| `AtLeast(n)` | The call is expected at least `n` times. |
| `AtMost(n)` | The call is expected at most `n` times. |
| `Between(m, n)` | The call is expected between `m` and `n` (inclusive) times. |
| `Exactly(n) or n` | The call is expected exactly `n` times. In particular, the call should never happen when `n` is 0. |
<!-- mdformat on -->
### Expectation Order
By default, the expectations can be matched in *any* order. If some or all
expectations must be matched in a given order, there are two ways to specify it.
They can be used either independently or together.
#### The After Clause {#AfterClause}
```cpp
using ::testing::Expectation;
...
Expectation init_x = EXPECT_CALL(foo, InitX());
Expectation init_y = EXPECT_CALL(foo, InitY());
EXPECT_CALL(foo, Bar())
.After(init_x, init_y);
```
says that `Bar()` can be called only after both `InitX()` and `InitY()` have
been called.
If you don't know how many pre-requisites an expectation has when you write it,
you can use an `ExpectationSet` to collect them:
```cpp
using ::testing::ExpectationSet;
...
ExpectationSet all_inits;
for (int i = 0; i < element_count; i++) {
all_inits += EXPECT_CALL(foo, InitElement(i));
}
EXPECT_CALL(foo, Bar())
.After(all_inits);
```
says that `Bar()` can be called only after all elements have been initialized
(but we don't care about which elements get initialized before the others).
Modifying an `ExpectationSet` after using it in an `.After()` doesn't affect the
meaning of the `.After()`.
#### Sequences {#UsingSequences}
When you have a long chain of sequential expectations, it's easier to specify
the order using **sequences**, which don't require you to given each expectation
in the chain a different name. *All expected calls* in the same sequence must
occur in the order they are specified.
```cpp
using ::testing::Return;
using ::testing::Sequence;
Sequence s1, s2;
...
EXPECT_CALL(foo, Reset())
.InSequence(s1, s2)
.WillOnce(Return(true));
EXPECT_CALL(foo, GetSize())
.InSequence(s1)
.WillOnce(Return(1));
EXPECT_CALL(foo, Describe(A<const char*>()))
.InSequence(s2)
.WillOnce(Return("dummy"));
```
says that `Reset()` must be called before *both* `GetSize()` *and* `Describe()`,
and the latter two can occur in any order.
To put many expectations in a sequence conveniently:
```cpp
using ::testing::InSequence;
{
InSequence seq;
EXPECT_CALL(...)...;
EXPECT_CALL(...)...;
...
EXPECT_CALL(...)...;
}
```
says that all expected calls in the scope of `seq` must occur in strict order.
The name `seq` is irrelevant.
### Verifying and Resetting a Mock
gMock will verify the expectations on a mock object when it is destructed, or
you can do it earlier:
```cpp
using ::testing::Mock;
...
// Verifies and removes the expectations on mock_obj;
// returns true if and only if successful.
Mock::VerifyAndClearExpectations(&mock_obj);
...
// Verifies and removes the expectations on mock_obj;
// also removes the default actions set by ON_CALL();
// returns true if and only if successful.
Mock::VerifyAndClear(&mock_obj);
```
You can also tell gMock that a mock object can be leaked and doesn't need to be
verified:
```cpp
Mock::AllowLeak(&mock_obj);
```
### Mock Classes
gMock defines a convenient mock class template
```cpp
class MockFunction<R(A1, ..., An)> {
public:
MOCK_METHOD(R, Call, (A1, ..., An));
};
```
See this [recipe](cook_book.md#using-check-points) for one application of it.
### Flags
<!-- mdformat off(no multiline tables) -->
| Flag | Description |
| :----------------------------- | :---------------------------------------- |
| `--gmock_catch_leaked_mocks=0` | Don't report leaked mock objects as failures. |
| `--gmock_verbose=LEVEL` | Sets the default verbosity level (`info`, `warning`, or `error`) of Google Mock messages. |
<!-- mdformat on -->

<b>P</b>ump is <b>U</b>seful for <b>M</b>eta <b>P</b>rogramming.
# The Problem
Template and macro libraries often need to define many classes, functions, or
macros that vary only (or almost only) in the number of arguments they take.
It's a lot of repetitive, mechanical, and error-prone work.
Our experience is that it's tedious to write custom scripts, which tend to
reflect the structure of the generated code poorly and are often hard to read
and edit. For example, a small change needed in the generated code may require
some non-intuitive, non-trivial changes in the script. This is especially
painful when experimenting with the code.
This script may be useful for generating meta code, for example a series of
macros of FOO1, FOO2, etc. Nevertheless, please make it your last resort
technique by favouring C++ template metaprogramming or variadic macros.
# Our Solution
Pump (for Pump is Useful for Meta Programming, Pretty Useful for Meta
Programming, or Practical Utility for Meta Programming, whichever you prefer) is
a simple meta-programming tool for C++. The idea is that a programmer writes a
`foo.pump` file which contains C++ code plus meta code that manipulates the C++
code. The meta code can handle iterations over a range, nested iterations, local
meta variable definitions, simple arithmetic, and conditional expressions. You
can view it as a small Domain-Specific Language. The meta language is designed
to be non-intrusive (s.t. it won't confuse Emacs' C++ mode, for example) and
concise, making Pump code intuitive and easy to maintain.
## Highlights
* The implementation is in a single Python script and thus ultra portable: no
build or installation is needed and it works cross platforms.
* Pump tries to be smart with respect to
[Google's style guide](https://github.com/google/styleguide): it breaks long
lines (easy to have when they are generated) at acceptable places to fit
within 80 columns and indent the continuation lines correctly.
* The format is human-readable and more concise than XML.
* The format works relatively well with Emacs' C++ mode.
## Examples
The following Pump code (where meta keywords start with `$`, `[[` and `]]` are
meta brackets, and `$$` starts a meta comment that ends with the line):
```
$var n = 3 $$ Defines a meta variable n.
$range i 0..n $$ Declares the range of meta iterator i (inclusive).
$for i [[
$$ Meta loop.
// Foo$i does blah for $i-ary predicates.
$range j 1..i
template <size_t N $for j [[, typename A$j]]>
class Foo$i {
$if i == 0 [[
blah a;
]] $elif i <= 2 [[
blah b;
]] $else [[
blah c;
]]
};
]]
```
will be translated by the Pump compiler to:
```cpp
// Foo0 does blah for 0-ary predicates.
template <size_t N>
class Foo0 {
blah a;
};
// Foo1 does blah for 1-ary predicates.
template <size_t N, typename A1>
class Foo1 {
blah b;
};
// Foo2 does blah for 2-ary predicates.
template <size_t N, typename A1, typename A2>
class Foo2 {
blah b;
};
// Foo3 does blah for 3-ary predicates.
template <size_t N, typename A1, typename A2, typename A3>
class Foo3 {
blah c;
};
```
In another example,
```
$range i 1..n
Func($for i + [[a$i]]);
$$ The text between i and [[ is the separator between iterations.
```
will generate one of the following lines (without the comments), depending on
the value of `n`:
```cpp
Func(); // If n is 0.
Func(a1); // If n is 1.
Func(a1 + a2); // If n is 2.
Func(a1 + a2 + a3); // If n is 3.
// And so on...
```
## Constructs
We support the following meta programming constructs:
| `$var id = exp` | Defines a named constant value. `$id` is |
: : valid util the end of the current meta :
: : lexical block. :
| :------------------------------- | :--------------------------------------- |
| `$range id exp..exp` | Sets the range of an iteration variable, |
: : which can be reused in multiple loops :
: : later. :
| `$for id sep [[ code ]]` | Iteration. The range of `id` must have |
: : been defined earlier. `$id` is valid in :
: : `code`. :
| `$($)` | Generates a single `$` character. |
| `$id` | Value of the named constant or iteration |
: : variable. :
| `$(exp)` | Value of the expression. |
| `$if exp [[ code ]] else_branch` | Conditional. |
| `[[ code ]]` | Meta lexical block. |
| `cpp_code` | Raw C++ code. |
| `$$ comment` | Meta comment. |
**Note:** To give the user some freedom in formatting the Pump source code, Pump
ignores a new-line character if it's right after `$for foo` or next to `[[` or
`]]`. Without this rule you'll often be forced to write very long lines to get
the desired output. Therefore sometimes you may need to insert an extra new-line
in such places for a new-line to show up in your output.
## Grammar
```ebnf
code ::= atomic_code*
atomic_code ::= $var id = exp
| $var id = [[ code ]]
| $range id exp..exp
| $for id sep [[ code ]]
| $($)
| $id
| $(exp)
| $if exp [[ code ]] else_branch
| [[ code ]]
| cpp_code
sep ::= cpp_code | empty_string
else_branch ::= $else [[ code ]]
| $elif exp [[ code ]] else_branch
| empty_string
exp ::= simple_expression_in_Python_syntax
```
## Code
You can find the source code of Pump in [scripts/pump.py](../scripts/pump.py).
It is still very unpolished and lacks automated tests, although it has been
successfully used many times. If you find a chance to use it in your project,
please let us know what you think! We also welcome help on improving Pump.
## Real Examples
You can find real-world applications of Pump in
[Google Test](https://github.com/google/googletest/tree/master/googletest) and
[Google Mock](https://github.com/google/googletest/tree/master/googlemock). The
source file `foo.h.pump` generates `foo.h`.
## Tips
* If a meta variable is followed by a letter or digit, you can separate them
using `[[]]`, which inserts an empty string. For example `Foo$j[[]]Helper`
generate `Foo1Helper` when `j` is 1.
* To avoid extra-long Pump source lines, you can break a line anywhere you
want by inserting `[[]]` followed by a new line. Since any new-line
character next to `[[` or `]]` is ignored, the generated code won't contain
this new line.

// ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
//
// where u_i is the desired type of v_i.
//
// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
// number of value parameters, but not on the number of template
// parameters. Without the restriction, the meaning of the following
// is unclear:
//
// OverloadedAction<int, bool>(x);
//
// Are we using a single-template-parameter action where 'bool' refers
// to the type of x, or are we using a two-template-parameter action
// where the compiler is asked to infer the type of x?
//
// Implementation notes:
//
// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
// implementing ACTION_TEMPLATE. The main trick we use is to create
// new macro invocations when expanding a macro. For example, we have
//
// #define ACTION_TEMPLATE(name, template_params, value_params)
// ... GMOCK_INTERNAL_DECL_##template_params ...
//
// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
// to expand to
//
// ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
//
// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
// preprocessor will continue to expand it to
//
// ... typename T ...
//
// This technique conforms to the C++ standard and is portable. It
// allows us to implement action templates using O(N) code, where N is
// the maximum number of template/value parameters supported. Without
// using it, we'd have to devote O(N^2) amount of code to implement all
// combinations of m and n.
// Declares the template parameters.

// Various overloads for InvokeArgument<N>().
//
// The InvokeArgument<N>(a1, a2, ..., a_k) action invokes the N-th
// (0-based) argument, which must be a k-ary callable, of the mock
// function, with arguments a1, a2, ..., a_k.
//
// Notes:
//
// 1. The arguments are passed by value by default. If you need to
// pass an argument by reference, wrap it inside ByRef(). For
// example,
//
// InvokeArgument<1>(5, string("Hello"), ByRef(foo))
//
// passes 5 and string("Hello") by value, and passes foo by
// reference.
//
// 2. If the callable takes an argument by reference but ByRef() is
// not used, it will receive the reference to a copy of the value,
// instead of the original value. For example, when the 0-th
// argument of the mock function takes a const string&, the action
//
// InvokeArgument<0>(string("Hello"))
//
// makes a copy of the temporary string("Hello") object and passes a
// reference of the copy, instead of the original temporary object,
// to the callable. This makes it easy for a user to define an
// InvokeArgument action from temporary values and have it performed
// later.

// Sometimes you want to give an action explicit template parameters
// that cannot be inferred from its value parameters. ACTION() and
// ACTION_P*() don't support that. ACTION_TEMPLATE() remedies that
// and can be viewed as an extension to ACTION() and ACTION_P*().
//
// The syntax:
//
// ACTION_TEMPLATE(ActionName,
// HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
// AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
//
// defines an action template that takes m explicit template
// parameters and n value parameters. name_i is the name of the i-th
// template parameter, and kind_i specifies whether it's a typename,
// an integral constant, or a template. p_i is the name of the i-th
// value parameter.
//
// Example:
//
// // DuplicateArg<k, T>(output) converts the k-th argument of the mock
// // function to type T and copies it to *output.
// ACTION_TEMPLATE(DuplicateArg,
// HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
// AND_1_VALUE_PARAMS(output)) {
// *output = T(::std::get<k>(args));
// }
// ...
// int n;
// EXPECT_CALL(mock, Foo(_, _))
// .WillOnce(DuplicateArg<1, unsigned char>(&n));
//
// To create an instance of an action template, write:
//
// ActionName<t1, ..., t_m>(v1, ..., v_n)
//
// where the ts are the template arguments and the vs are the value
// arguments. The value argument types are inferred by the compiler.
// If you want to explicitly specify the value argument types, you can
// provide additional template arguments:
//
// ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
//
// where u_i is the desired type of v_i.
//
// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
// number of value parameters, but not on the number of template
// parameters. Without the restriction, the meaning of the following
// is unclear:
//
// OverloadedAction<int, bool>(x);
//
// Are we using a single-template-parameter action where 'bool' refers
// to the type of x, or are we using a two-template-parameter action
// where the compiler is asked to infer the type of x?
//
// Implementation notes:
//
// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
// implementing ACTION_TEMPLATE. The main trick we use is to create
// new macro invocations when expanding a macro. For example, we have
//
// #define ACTION_TEMPLATE(name, template_params, value_params)
// ... GMOCK_INTERNAL_DECL_##template_params ...
//
// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
// to expand to
//
// ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
//
// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
// preprocessor will continue to expand it to
//
// ... typename T ...
//
// This technique conforms to the C++ standard and is portable. It
// allows us to implement action templates using O(N) code, where N is
// the maximum number of template/value parameters supported. Without
// using it, we'd have to devote O(N^2) amount of code to implement all
// combinations of m and n.

"""fuse_gmock_files.py v0.1.0
Fuses Google Mock and Google Test source code into two .h files and a .cc file.
SYNOPSIS
fuse_gmock_files.py [GMOCK_ROOT_DIR] OUTPUT_DIR
Scans GMOCK_ROOT_DIR for Google Mock and Google Test source
code, assuming Google Test is in the GMOCK_ROOT_DIR/../googletest
directory, and generates three files:
OUTPUT_DIR/gtest/gtest.h, OUTPUT_DIR/gmock/gmock.h, and
OUTPUT_DIR/gmock-gtest-all.cc. Then you can build your tests
by adding OUTPUT_DIR to the include search path and linking
with OUTPUT_DIR/gmock-gtest-all.cc. These three files contain
everything you need to use Google Mock. Hence you can
"install" Google Mock by copying them to wherever you want.
GMOCK_ROOT_DIR can be omitted and defaults to the parent
directory of the directory holding this script.
EXAMPLES
./fuse_gmock_files.py fused_gmock
./fuse_gmock_files.py path/to/unpacked/gmock fused_gmock
This tool is experimental. In particular, it assumes that there is no
conditional inclusion of Google Mock or Google Test headers. Please
report any problems to googlemock@googlegroups.com. You can read
https://github.com/google/googletest/blob/master/googlemock/docs/cook_book.md for more

The Google Mock class generator is an application that is part of cppclean.
For more information about cppclean, visit http://code.google.com/p/cppclean/
The mock generator requires Python 2.3.5 or later. If you don't have Python
installed on your system, you will also need to install it. You can download
Python from: http://www.python.org/download/releases/
To use the Google Mock class generator, you need to call it
on the command line passing the header file and class for which you want
to generate a Google Mock class.
Make sure to install the scripts somewhere in your path. Then you can
run the program.
gmock_gen.py header-file.h [ClassName]...
If no ClassNames are specified, all classes in the file are emitted.
To change the indentation from the default of 2, set INDENT in
the environment. For example to use an indent of 4 spaces:
INDENT=4 gmock_gen.py header-file.h ClassName
This version was made from SVN revision 281 in the cppclean repository.
Known Limitations
-----------------
Not all code will be generated properly. For example, when mocking templated
classes, the template information is lost. You will need to add the template
information manually.
Not all permutations of using multiple pointers/references will be rendered
properly. These will also have to be fixed manually.

Goal:
-----
CppClean attempts to find problems in C++ source that slow development
in large code bases, for example various forms of unused code.
Unused code can be unused functions, methods, data members, types, etc
to unnecessary #include directives. Unnecessary #includes can cause
considerable extra compiles increasing the edit-compile-run cycle.
The project home page is: http://code.google.com/p/cppclean/
Features:
---------
* Find and print C++ language constructs: classes, methods, functions, etc.
* Find classes with virtual methods, no virtual destructor, and no bases
* Find global/static data that are potential problems when using threads
* Unnecessary forward class declarations
* Unnecessary function declarations
* Undeclared function definitions
* (planned) Find unnecessary header files #included
- No direct reference to anything in the header
- Header is unnecessary if classes were forward declared instead
* (planned) Source files that reference headers not directly #included,
ie, files that rely on a transitive #include from another header
* (planned) Unused members (private, protected, & public) methods and data
* (planned) Store AST in a SQL database so relationships can be queried
AST is Abstract Syntax Tree, a representation of parsed source code.
http://en.wikipedia.org/wiki/Abstract_syntax_tree
System Requirements:
--------------------
* Python 2.4 or later (2.3 probably works too)
* Works on Windows (untested), Mac OS X, and Unix
How to Run:
-----------
For all examples, it is assumed that cppclean resides in a directory called
/cppclean.
To print warnings for classes with virtual methods, no virtual destructor and
no base classes:
/cppclean/run.sh nonvirtual_dtors.py file1.h file2.h file3.cc ...
To print all the functions defined in header file(s):
/cppclean/run.sh functions.py file1.h file2.h ...
All the commands take multiple files on the command line. Other programs
include: find_warnings, headers, methods, and types. Some other programs
are available, but used primarily for debugging.
run.sh is a simple wrapper that sets PYTHONPATH to /cppclean and then
runs the program in /cppclean/cpp/PROGRAM.py. There is currently
no equivalent for Windows. Contributions for a run.bat file
would be greatly appreciated.
How to Configure:
-----------------
You can add a siteheaders.py file in /cppclean/cpp to configure where
to look for other headers (typically -I options passed to a compiler).
Currently two values are supported: _TRANSITIVE and GetIncludeDirs.
_TRANSITIVE should be set to a boolean value (True or False) indicating
whether to transitively process all header files. The default is False.
GetIncludeDirs is a function that takes a single argument and returns
a sequence of directories to include. This can be a generator or
return a static list.
def GetIncludeDirs(filename):
return ['/some/path/with/other/headers']
# Here is a more complicated example.
def GetIncludeDirs(filename):
yield '/path1'
yield os.path.join('/path2', os.path.dirname(filename))
yield '/path3'
How to Test:
------------
For all examples, it is assumed that cppclean resides in a directory called
/cppclean. The tests require
cd /cppclean
make test
# To generate expected results after a change:
make expected
Current Status:
---------------
The parser works pretty well for header files, parsing about 99% of Google's
header files. Anything which inspects structure of C++ source files should
work reasonably well. Function bodies are not transformed to an AST,
but left as tokens. Much work is still needed on finding unused header files
and storing an AST in a database.
Non-goals:
----------
* Parsing all valid C++ source
* Handling invalid C++ source gracefully
* Compiling to machine code (or anything beyond an AST)
Contact:
--------
If you used cppclean, I would love to hear about your experiences
cppclean@googlegroups.com. Even if you don't use cppclean, I'd like to
hear from you. :-) (You can contact me directly at: nnorwitz@gmail.com)

"""pump v0.2.0 - Pretty Useful for Meta Programming.
A tool for preprocessor meta programming. Useful for generating
repetitive boilerplate code. Especially useful for writing C++
classes, functions, macros, and templates that need to work with
various number of arguments.
USAGE:
pump.py SOURCE_FILE
EXAMPLES:
pump.py foo.cc.pump
Converts foo.cc.pump to foo.cc.
GRAMMAR:
CODE ::= ATOMIC_CODE*
ATOMIC_CODE ::= $var ID = EXPRESSION
| $var ID = [[ CODE ]]
| $range ID EXPRESSION..EXPRESSION
| $for ID SEPARATOR [[ CODE ]]
| $($)
| $ID
| $(EXPRESSION)
| $if EXPRESSION [[ CODE ]] ELSE_BRANCH
| [[ CODE ]]
| RAW_CODE
SEPARATOR ::= RAW_CODE | EMPTY
ELSE_BRANCH ::= $else [[ CODE ]]
| $elif EXPRESSION [[ CODE ]] ELSE_BRANCH
| EMPTY
EXPRESSION has Python syntax.
