Google C++ Testing Framework
============================
http://code.google.com/p/googletest/
Overview
--------
Google's framework for writing C++ tests on a variety of platforms (Linux, Mac
OS X, Windows, Windows CE, Symbian, and etc). Based on the xUnit architecture.
Supports automatic test discovery, a rich set of assertions, user-defined
assertions, death tests, fatal and non-fatal failures, various options for
running the tests, and XML test report generation.
Please see the project page above for more information as well as mailing lists
for questions, discussions, and development. There is also an IRC channel on
OFTC (irc.oftc.net) #gtest available. Please join us!
Requirements
------------
Google Test is designed to have fairly minimal requirements to build
and use with your projects, but there are some. Currently, we support
building Google Test on Linux, Windows, Mac OS X, and Cygwin. We will
also make our best effort to support other platforms (e.g. Solaris and
IBM z/OS). However, since core members of the Google Test project
have no access to them, Google Test may have outstanding issues on
these platforms. If you notice any problems on your platform, please
notify googletestframework@googlegroups.com (patches for fixing them
are even more welcome!).
### Linux Requirements ###
These are the base requirements to build and use Google Test from a source
package (as described below):
* GNU-compatible Make or "gmake"
* POSIX-standard shell
* POSIX(-2) Regular Expressions (regex.h)
* A C++98 standards compliant compiler
Furthermore, if you are building Google Test from a VCS Checkout (also
described below), there are further requirements:
* Automake version 1.9 or newer
* Autoconf version 2.59 or newer
* Libtool / Libtoolize
* Python version 2.4 or newer
### Windows Requirements ###
* Microsoft Visual Studio 7.1 or newer
### Cygwin Requirements ###
* Cygwin 1.5.25-14 or newer
### Mac OS X Requirements ###
* Mac OS X 10.4 Tiger or newer
* Developer Tools Installed
* Optional: Xcode 2.5 or later for univeral-binary framework; see note below.
Getting the Source
------------------
There are two primary ways of getting Google Test's source code: you can
download a source release in your preferred archive format, or directly check
out the source from a Version Control System (VCS, we use Google Code's
Subversion hosting). The VCS checkout requires a few extra steps and some extra
software packages on your system, but lets you track development, and make
patches to contribute much more easily, so we highly encourage it.
### VCS Checkout: ###
The first step is to select whether you want to check out the main line of
development on Google Test, or one of the released branches. The former will be
much more active and have the latest features, but the latter provides much
more stability and predictability. Choose whichever fits your needs best, and
proceed with the following Subversion commands:
svn checkout http://googletest.googlecode.com/svn/trunk/ gtest-svn
or for a release version X.Y.*'s branch:
svn checkout http://googletest.googlecode.com/svn/branches/release-X.Y/ \
gtest-X.Y-svn
Next you will need to prepare the GNU Autotools build system, if you
are using Linux, Mac OS X, or Cygwin. Enter the target directory of
the checkout command you used ('gtest-svn' or 'gtest-X.Y-svn' above)
and proceed with the following command:
autoreconf -fvi
Once you have completed this step, you are ready to build the library. Note
that you should only need to complete this step once. The subsequent `make'
invocations will automatically re-generate the bits of the build system that
need to be changed.
If your system uses older versions of the autotools, the above command will
fail. You may need to explicitly specify a version to use. For instance, if you
have both GNU Automake 1.4 and 1.9 installed and `automake' would invoke the
1.4, use instead:
AUTOMAKE=automake-1.9 ACLOCAL=aclocal-1.9 autoreconf -fvi
Make sure you're using the same version of automake and aclocal.
### Source Package: ###
Google Test is also released in source packages which can be downloaded from
its Google Code download page[1]. Several different archive formats are
provided, but the only difference is the tools used to manipulate them, and the
size of the resulting file. Download whichever you are most comfortable with.
[1] Google Test Downloads: http://code.google.com/p/googletest/downloads/list
Once downloaded expand the archive using whichever tools you prefer for that
type. This will always result in a new directory with the name "gtest-X.Y.Z"
which contains all of the source code. Here are some examples in Linux:
tar -xvzf gtest-X.Y.Z.tar.gz
tar -xvjf gtest-X.Y.Z.tar.bz2
unzip gtest-X.Y.Z.zip
Building the Source
-------------------
### Linux, Mac OS X (without Xcode), and Cygwin ###
There are two primary options for building the source at this point: build it
inside the source code tree, or in a separate directory. We recommend building
in a separate directory as that tends to produce both more consistent results
and be easier to clean up should anything go wrong, but both patterns are
supported. The only hard restriction is that while the build directory can be
a subdirectory of the source directory, the opposite is not possible and will
result in errors. Once you have selected where you wish to build Google Test,
create the directory if necessary, and enter it. The following steps apply for
either approach by simply substituting the shell variable SRCDIR with "." for
building inside the source directory, and the relative path to the source
directory otherwise.
${SRCDIR}/configure # Standard GNU configure script, --help for more info
make # Standard makefile following GNU conventions
make check # Builds and runs all tests - all should pass
Other programs will only be able to use Google Test's functionality if you
install it in a location which they can access, in Linux this is typically
under '/usr/local'. The following command will install all of the Google Test
libraries, public headers, and utilities necessary for other programs and
libraries to leverage it:
sudo make install # Not necessary, but allows use by other programs
Should you need to remove Google Test from your system after having installed
it, run the following command, and it will back out its changes. However, note
carefully that you must run this command on the *same* Google Test build that
you ran the install from, or the results are not predictable. If you install
Google Test on your system, and are working from a VCS checkout, make sure you
run this *before* updating your checkout of the source in order to uninstall
the same version which you installed.
sudo make uninstall # Must be run against the exact same build as "install"
Your project can build against Google Test simply by leveraging the
'gtest-config' script. This script can be invoked directly out of the 'scripts'
subdirectory of the build tree, and it will be installed in the binary
directory specified during the 'configure'. Here are some examples of its use,
see 'gtest-config --help' for more detailed information.
gtest-config --min-version=1.0 || echo "Insufficient Google Test version."
g++ $(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp
g++ $(gtest-config --ldflags --libs) -o foo foo.o
# When using a built but not installed Google Test:
g++ $(../../my_gtest_build/scripts/gtest-config ...) ...
### Windows ###
Open the gtest.sln file in the msvc/ folder using Visual Studio, and
you are ready to build Google Test the same way you build any Visual
Studio project.
### Mac OS X (universal-binary framework) ###
Open the gtest.xcodeproj in the xcode/ folder using Xcode. Build the "gtest"
target. The universal binary framework will end up in your selected build
directory (selected in the Xcode "Preferences..." -> "Building" pane and
defaults to xcode/build). Alternatively, at the command line, enter:
xcodebuild
This will build the "Release" configuration of the gtest.framework, but you can
select the "Debug" configuration with a command line option. See the
"xcodebuild" man page for more information.
To test the gtest.framework in Xcode, change the active target to "Check" and
then build. This target builds all of the tests and then runs them. Don't worry
if you see some errors. Xcode reports all test failures (even the intentional
ones) as errors. However, you should see a "Build succeeded" message at the end
of the build log. To run all of the tests from the command line, enter:
xcodebuid -target Check
It is also possible to build and execute individual tests within Xcode. Each
test has its own Xcode "Target" and Xcode "Executable". To build any of the
tests, change the active target and the active executable to the test of
interest and then build and run.
NOTE: Several tests use a Python script to run the test executable. These can be
run from Xcode by creating a "Custom Executable". For example, to run the Python
script which executes the gtest_color_test, select the Project->New Custom
Executable... menu item. When prompted, set the "Executable Name" to something
like "run_gtest_color_test" and set the "Executable Path" to the path of the
gtest_color_test.py script. Finally, choose "Run" from the Run menu and check
the Console for the results.
Individual tests can be built from the command line using:
xcodebuild -target <test_name>
These tests can be executed from the command line by moving to the build
directory and then (in bash)
export DYLD_FRAMEWORK_PATH=`pwd`
./<test_name> # (if it is not a python test, e.g. ./gtest_unittest)
# OR
./<test_name>.py # (if it is a python test, e.g. ./gtest_color_test.py)
To use the gtest.framework for your own tests, first, add the framework to Xcode
project. Next, create a new executable target and add the framework to the
"Link Binary With Libraries" build phase. Select "Edit Active Executable" from
the "Project" menu. In the "Arguments" tab, add
"DYLD_FRAMEWORK_PATH" : "/real/framework/path"
in the "Variables to be set in the environment:" list, where you replace
"/real/framework/path" with the actual location of the gtest.framework. Now
when you run your executable, it will load the framework and your test will
run as expected.
### Using GNU Make ###
The make/ directory contains a Makefile that you can use to build
Google Test on systems where GNU make is available (e.g. Linux, Mac OS
X, and Cygwin). It doesn't try to build Google Test's own tests.
Instead, it just builds the Google Test library and a sample test.
You can use it as a starting point for your own Makefile.
If the default settings are correct for your environment, the
following commands should succeed:
cd ${SRCDIR}/make
make
./sample1_unittest
If you see errors, try to tweak the contents of make/Makefile to make
them go away. There are instructions in make/Makefile on how to do
it.
### Using Your Own Build System ###
If none of the build solutions we provide works for you, or if you
prefer your own build system, you just need to compile
src/gtest-all.cc into a library and link your tests with it. Assuming
a Linux-like system and gcc, something like the following will do:
cd ${SRCDIR}
g++ -I. -I./include -c src/gtest-all.cc
ar -rv libgtest.a gtest-all.o
g++ -I. -I./include path/to/your_test.cc libgtest.a -o your_test
Regenerating Source Files
-------------------------
Some of Google Test's source files are generated from templates (not
in the C++ sense) using a script. A template file is named FOO.pump,
where FOO is the name of the file it will generate. For example, the
file include/gtest/internal/gtest-type-util.h.pump is used to generate
gtest-type-util.h in the same directory.
Normally you don't need to worry about regenerating the source files,
unless you need to modify them (e.g. if you are working on a patch for
Google Test). In that case, you should modify the corresponding .pump
files instead and run the 'pump' script (for Pump is Useful for Meta
Programming) to regenerate them. We are still working on releasing
the script and its documentation. If you need it now, please email
googletestframework@googlegroups.com such that we know to make it
happen sooner.
Happy testing!

// This flag controls the style of death tests. Valid values are "threadsafe",

#if GTEST_HAS_DEATH_TEST
// The following macros are useful for writing death tests.
// Here's what happens when an ASSERT_DEATH* or EXPECT_DEATH* is
// executed:
//
// 1. It generates a warning if there is more than one active
// thread. This is because it's safe to fork() or clone() only
// when there is a single thread.
//
// 2. The parent process clone()s a sub-process and runs the death
// test in it; the sub-process exits with code 0 at the end of the
// death test, if it hasn't exited already.
//
// 3. The parent process waits for the sub-process to terminate.
//
// 4. The parent process checks the exit code and error message of
// the sub-process.
//
// Examples:
//
// ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
// for (int i = 0; i < 5; i++) {
// EXPECT_DEATH(server.ProcessRequest(i),
// "Invalid request .* in ProcessRequest()")
// << "Failed to die on request " << i);
// }
//
// ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
//
// bool KilledBySIGHUP(int exit_code) {
// return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
// }
//
// ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
//
// On the regular expressions used in death tests:
//
// On POSIX-compliant systems (*nix), we use the <regex.h> library,
// which uses the POSIX extended regex syntax.
//
// On other platforms (e.g. Windows), we only support a simple regex
// syntax implemented as part of Google Test. This limited
// implementation should be enough most of the time when writing
// death tests; though it lacks many features you can find in PCRE
// or POSIX extended regex syntax. For example, we don't support
// union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
// repetition count ("x{5,7}"), among others.
//
// Below is the syntax that we do support. We chose it to be a
// subset of both PCRE and POSIX extended regex, so it's easy to
// learn wherever you come from. In the following: 'A' denotes a
// literal character, period (.), or a single \\ escape sequence;
// 'x' and 'y' denote regular expressions; 'm' and 'n' are for
// natural numbers.
//
// c matches any literal character c
// \\d matches any decimal digit
// \\D matches any character that's not a decimal digit
// \\f matches \f
// \\n matches \n
// \\r matches \r
// \\s matches any ASCII whitespace, including \n
// \\S matches any character that's not a whitespace
// \\t matches \t
// \\v matches \v
// \\w matches any letter, _, or decimal digit
// \\W matches any character that \\w doesn't match
// \\c matches any literal character c, which must be a punctuation
// . matches any single character except \n
// A? matches 0 or 1 occurrences of A
// A* matches 0 or many occurrences of A
// A+ matches 1 or many occurrences of A
// ^ matches the beginning of a string (not that of each line)
// $ matches the end of a string (not that of each line)
// xy matches x followed by y
//
// If you accidentally use PCRE or POSIX extended regex features
// not implemented by us, you will get a run-time failure. In that
// case, please try to rewrite your regular expression within the
// above syntax.
//
// This implementation is *not* meant to be as highly tuned or robust
// as a compiled regex library, but should perform well enough for a
// death test, which already incurs significant overhead by launching
// a child process.
//
// Known caveats:
//
// A "threadsafe" style death test obtains the path to the test
// program from argv[0] and re-executes it in the sub-process. For
// simplicity, the current implementation doesn't search the PATH
// when launching the sub-process. This means that the user must
// invoke the test program via a path that contains at least one
// path separator (e.g. path/to/foo_test and
// /absolute/path/to/bar_test are fine, but foo_test is not). This
// is rarely a problem as people usually don't put the test binary
// directory in PATH.
//
// TODO(wan@google.com): make thread-safe death tests search the PATH.

// EXPECT_DEBUG_DEATH asserts that the given statements die in debug mode.
// The death testing framework causes this to have interesting semantics,

//
// In practice, this can be used to test functions that utilize the

//
// int DieInDebugOr12(int* sideeffect) {
// if (sideeffect) {
// *sideeffect = 12;

// return 12;

// // opt-mode has sideeffect visible.
// EXPECT_EQ(12, sideeffect);
// #else
// // dbg-mode no visible sideeffect.
// EXPECT_EQ(0, sideeffect);
// #endif
// }
//
// This will assert that DieInDebugReturn12InOpt() crashes in debug
// mode, usually due to a DCHECK or LOG(DFATAL), but returns the
// appropriate fallback value (12 in this case) in opt mode. If you
// need to test that a function has appropriate side-effects in opt

//
// EXPECT_DEBUG_DEATH({

// Value-parameterized tests allow you to test your code with different
// parameters without writing multiple copies of the same test.
//
// Here is how you use value-parameterized tests:
#if 0
// To write value-parameterized tests, first you should define a fixture
// class. It must be derived from testing::TestWithParam<T>, where T is
// the type of your parameter values. TestWithParam<T> is itself derived
// from testing::Test. T can be any copyable type. If it's a raw pointer,
// you are responsible for managing the lifespan of the pointed values.
class FooTest : public ::testing::TestWithParam<const char*> {
// You can implement all the usual class fixture members here.
};
// Then, use the TEST_P macro to define as many parameterized tests
// for this fixture as you want. The _P suffix is for "parameterized"
// or "pattern", whichever you prefer to think.
TEST_P(FooTest, DoesBlah) {
// Inside a test, access the test parameter with the GetParam() method
// of the TestWithParam<T> class:
EXPECT_TRUE(foo.Blah(GetParam()));
...
}
TEST_P(FooTest, HasBlahBlah) {
...
}
// Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test
// case with any set of parameters you want. Google Test defines a number
// of functions for generating test parameters. They return what we call
// (surprise!) parameter generators. Here is a summary of them, which
// are all in the testing namespace:
//
//
// Range(begin, end [, step]) - Yields values {begin, begin+step,
// begin+step+step, ...}. The values do not
// include end. step defaults to 1.
// Values(v1, v2, ..., vN) - Yields values {v1, v2, ..., vN}.
// ValuesIn(container) - Yields values from a C-style array, an STL
// ValuesIn(begin,end) container, or an iterator range [begin, end).
// Bool() - Yields sequence {false, true}.
// Combine(g1, g2, ..., gN) - Yields all combinations (the Cartesian product
// for the math savvy) of the values generated
// by the N generators.
//
// For more details, see comments at the definitions of these functions below
// in this file.
//
// The following statement will instantiate tests from the FooTest test case
// each with parameter values "meeny", "miny", and "moe".
INSTANTIATE_TEST_CASE_P(InstantiationName,
FooTest,
Values("meeny", "miny", "moe"));
// To distinguish different instances of the pattern, (yes, you
// can instantiate it more then once) the first argument to the
// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
// actual test case name. Remember to pick unique prefixes for different
// instantiations. The tests from the instantiation above will have
// these names:
//
// * InstantiationName/FooTest.DoesBlah/0 for "meeny"
// * InstantiationName/FooTest.DoesBlah/1 for "miny"
// * InstantiationName/FooTest.DoesBlah/2 for "moe"
// * InstantiationName/FooTest.HasBlahBlah/0 for "meeny"
// * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
// * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
//
// You can use these names in --gtest_filter.
//
// This statement will instantiate all tests from FooTest again, each
// with parameter values "cat" and "dog":
const char* pets[] = {"cat", "dog"};
INSTANTIATE_TEST_CASE_P(AnotherInstantiationName, FooTest, ValuesIn(pets));
// The tests from the instantiation above will have these names:
//
// * AnotherInstantiationName/FooTest.DoesBlah/0 for "cat"
// * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog"
// * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
// * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
//
// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
// in the given test case, whether their definitions come before or
// AFTER the INSTANTIATE_TEST_CASE_P statement.
//
// Please also note that generator expressions are evaluated in
// RUN_ALL_TESTS(), after main() has started. This allows evaluation of
// parameter list based on command line parameters.
//
// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
// for more examples.
//
// In the future, we plan to publish the API for defining new parameter
// generators. But for now this interface remains part of the internal
// implementation and is subject to change.

// Google Test uses these generators to produce parameters for value-

// Synopsis:
// Range(start, end)
// - returns a generator producing a sequence of values {start, start+1,

// Range(start, end, step)
// - returns a generator producing a sequence of values {start, start+step,
// start+step+step, ..., }.
// Notes:
// * The generated sequences never include end. For example, Range(1, 5)
// returns a generator producing a sequence {1, 2, 3, 4}. Range(1, 9, 2)
// returns a generator producing {1, 3, 5, 7}.
// * start and end must have the same type. That type may be any integral or
// floating-point type or a user defined type satisfying these conditions:
// * It must be assignable (have operator=() defined).
// * It must have operator+() (operator+(int-compatible type) for
// two-operand version).
// * It must have operator<() defined.
// Elements in the resulting sequences will also have that type.
// * Condition start < end must be satisfied in order for resulting sequences
// to contain any elements.

// Synopsis:

// tuple<T1, T2, ..., TN> where T1, T2, ..., TN are the types
// of elements from sequences produces by gen1, gen2, ..., genN.

// Combine can have up to $maxtuple arguments. This number is currently limited
// by the maximum number of elements in the tuple implementation used by Google
// Test.
//
// Example:
//
// This will instantiate tests in test case AnimalTest each one with
// the parameter values tuple("cat", BLACK), tuple("cat", WHITE),
// tuple("dog", BLACK), and tuple("dog", WHITE):

// enum Color { BLACK, GRAY, WHITE };

//
// class FlagDependentTest
// : public testing::TestWithParam<tuple(bool, bool)> > {
// virtual void SetUp() {
// // Assigns external_flag_1 and external_flag_2 values from the tuple.
// tie(external_flag_1, external_flag_2) = GetParam();

// This header implements typed tests and type-parameterized tests.
// Typed (aka type-driven) tests repeat the same test for types in a
// list. You must know which types you want to test with when writing
// typed tests. Here's how you do it:
#if 0
// First, define a fixture class template. It should be parameterized
// by a type. Remember to derive it from testing::Test.
template <typename T>
class FooTest : public testing::Test {
public:
...
typedef std::list<T> List;
static T shared_;
T value_;
};
// Next, associate a list of types with the test case, which will be
// repeated for each type in the list. The typedef is necessary for
// the macro to parse correctly.
typedef testing::Types<char, int, unsigned int> MyTypes;
TYPED_TEST_CASE(FooTest, MyTypes);
// If the type list contains only one type, you can write that type
// directly without Types<...>:
// TYPED_TEST_CASE(FooTest, int);
// Then, use TYPED_TEST() instead of TEST_F() to define as many typed
// tests for this test case as you want.
TYPED_TEST(FooTest, DoesBlah) {
// Inside a test, refer to TypeParam to get the type parameter.
// Since we are inside a derived class template, C++ requires use to
// visit the members of FooTest via 'this'.
TypeParam n = this->value_;
// To visit static members of the fixture, add the TestFixture::
// prefix.
n += TestFixture::shared_;
// To refer to typedefs in the fixture, add the "typename
// TestFixture::" prefix.
typename TestFixture::List values;
values.push_back(n);
...
}
TYPED_TEST(FooTest, HasPropertyA) { ... }
#endif // 0
// Type-parameterized tests are abstract test patterns parameterized
// by a type. Compared with typed tests, type-parameterized tests
// allow you to define the test pattern without knowing what the type
// parameters are. The defined pattern can be instantiated with
// different types any number of times, in any number of translation
// units.
//
// If you are designing an interface or concept, you can define a
// suite of type-parameterized tests to verify properties that any
// valid implementation of the interface/concept should have. Then,
// each implementation can easily instantiate the test suite to verify
// that it conforms to the requirements, without having to write
// similar tests repeatedly. Here's an example:
#if 0
// First, define a fixture class template. It should be parameterized
// by a type. Remember to derive it from testing::Test.
template <typename T>
class FooTest : public testing::Test {
...
};
// Next, declare that you will define a type-parameterized test case
// (the _P suffix is for "parameterized" or "pattern", whichever you
// prefer):
TYPED_TEST_CASE_P(FooTest);
// Then, use TYPED_TEST_P() to define as many type-parameterized tests
// for this type-parameterized test case as you want.
TYPED_TEST_P(FooTest, DoesBlah) {
// Inside a test, refer to TypeParam to get the type parameter.
TypeParam n = 0;
...
}
TYPED_TEST_P(FooTest, HasPropertyA) { ... }
// Now the tricky part: you need to register all test patterns before
// you can instantiate them. The first argument of the macro is the
// test case name; the rest are the names of the tests in this test
// case.
REGISTER_TYPED_TEST_CASE_P(FooTest,
DoesBlah, HasPropertyA);
// Finally, you are free to instantiate the pattern with the types you
// want. If you put the above code in a header file, you can #include
// it in multiple C++ source files and instantiate it multiple times.
//
// To distinguish different instances of the pattern, the first
// argument to the INSTANTIATE_* macro is a prefix that will be added
// to the actual test case name. Remember to pick unique prefixes for
// different instances.
typedef testing::Types<char, int, unsigned int> MyTypes;
INSTANTIATE_TYPED_TEST_CASE_P(My, FooTest, MyTypes);

// directly without Types<...>:

//
// A "smart" pointer type with reference tracking. Every pointer to a
// particular object is kept on a circular linked list. When the last pointer
// to an object is destroyed or reassigned, the object is deleted.
//
// Used properly, this deletes the object when the last reference goes away.
// There are several caveats:
// - Like all reference counting schemes, cycles lead to leaks.
// - Each smart pointer is actually two pointers (8 bytes instead of 4).
// - Every time a pointer is assigned, the entire list of pointers to that
// object is traversed. This class is therefore NOT SUITABLE when there
// will often be more than two or three pointers to a particular object.
// - References are only tracked as long as linked_ptr<> objects are copied.
// If a linked_ptr<> is converted to a raw pointer and back, BAD THINGS
// will happen (double deletion).
//
// A good use of this class is storing object references in STL containers.
// You can safely put linked_ptr<> in a vector<>.
// Other uses may not be as good.
//
// Note: If you use an incomplete type with linked_ptr<>, the class
// *containing* linked_ptr<> must have a constructor and destructor (even
// if they do nothing!).
//
// Bill Gibbons suggested we use something like this.
//
// Thread Safety:
// Unlike other linked_ptr implementations, in this implementation
// a linked_ptr object is thread-safe in the sense that:

// The user can define the following macros in the build script to
// control Google Test's behavior. If the user doesn't define a macro
// in this list, Google Test will define it.
//
// GTEST_HAS_CLONE - Define it to 1/0 to indicate that clone(2)
// is/isn't available.
// GTEST_HAS_GLOBAL_STRING - Define it to 1/0 to indicate that ::string
// is/isn't available (some systems define
// ::string, which is different to std::string).
// GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::string
// is/isn't available (some systems define
// ::wstring, which is different to std::wstring).
// GTEST_HAS_PTHREAD - Define it to 1/0 to indicate that <pthread.h>
// is/isn't available.
// GTEST_HAS_RTTI - Define it to 1/0 to indicate that RTTI is/isn't
// enabled.
// GTEST_HAS_STD_STRING - Define it to 1/0 to indicate that
// std::string does/doesn't work (Google Test can
// be used where std::string is unavailable).
// GTEST_HAS_STD_WSTRING - Define it to 1/0 to indicate that
// std::wstring does/doesn't work (Google Test can
// be used where std::wstring is unavailable).
// GTEST_HAS_TR1_TUPLE 1 - Define it to 1/0 to indicate tr1::tuple
// is/isn't available.
// This header defines the following utilities:
//
// Macros indicating the current platform (defined to 1 if compiled on
// the given platform; otherwise undefined):
// GTEST_OS_CYGWIN - Cygwin
// GTEST_OS_LINUX - Linux
// GTEST_OS_MAC - Mac OS X
// GTEST_OS_SOLARIS - Sun Solaris
// GTEST_OS_SYMBIAN - Symbian
// GTEST_OS_WINDOWS - Windows
// GTEST_OS_ZOS - z/OS
//
// Among the platforms, Cygwin, Linux, Max OS X, and Windows have the
// most stable support. Since core members of the Google Test project
// don't have access to other platforms, support for them may be less
// stable. If you notice any problems on your platform, please notify
// googletestframework@googlegroups.com (patches for fixing them are
// even more welcome!).
//
// Note that it is possible that none of the GTEST_OS_* macros are defined.
//
// Macros indicating available Google Test features (defined to 1 if
// the corresponding feature is supported; otherwise undefined):
// GTEST_HAS_COMBINE - the Combine() function (for value-parameterized
// tests)
// GTEST_HAS_DEATH_TEST - death tests
// GTEST_HAS_PARAM_TEST - value-parameterized tests
// GTEST_HAS_TYPED_TEST - typed tests
// GTEST_HAS_TYPED_TEST_P - type-parameterized tests
// GTEST_USES_POSIX_RE - enhanced POSIX regex is used.
// GTEST_USES_SIMPLE_RE - our own simple regex is used;
// the above two are mutually exclusive.
//
// Macros for basic C++ coding:
// GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
// GTEST_ATTRIBUTE_UNUSED_ - declares that a class' instances don't have to
// be used.
// GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=.
// GTEST_MUST_USE_RESULT_ - declares that a function's result must be used.
//
// Synchronization:
// Mutex, MutexLock, ThreadLocal, GetThreadCount()
// - synchronization primitives.
// GTEST_IS_THREADSAFE - defined to 1 to indicate that the above
// synchronization primitives have real implementations
// and Google Test is thread-safe; or 0 otherwise.
//
// Template meta programming:
// is_pointer - as in TR1; needed on Symbian and IBM XL C/C++ only.
//
// Smart pointers:
// scoped_ptr - as in TR2.
//
// Regular expressions:
// RE - a simple regular expression class using the POSIX
// Extended Regular Expression syntax. Not available on
// Windows.
//
// Logging:
// GTEST_LOG_() - logs messages at the specified severity level.
// LogToStderr() - directs all log messages to stderr.
// FlushInfoLog() - flushes informational log messages.
//
// Stderr capturing:
// CaptureStderr() - starts capturing stderr.
// GetCapturedStderr() - stops capturing stderr and returns the captured
// string.
//
// Integer types:
// TypeWithSize - maps an integer to a int type.
// Int32, UInt32, Int64, UInt64, TimeInMillis
// - integers of known sizes.
// BiggestInt - the biggest signed integer type.
//
// Command-line utilities:
// GTEST_FLAG() - references a flag.
// GTEST_DECLARE_*() - declares a flag.
// GTEST_DEFINE_*() - defines a flag.
// GetArgvs() - returns the command line as a vector of strings.

// A sample program demonstrating using Google C++ testing framework.
//
// Author: wan@google.com (Zhanyong Wan)
// This sample shows how to write a simple unit test for a function,
// using Google C++ testing framework.
//
// Writing a unit test using Google C++ testing framework is easy as 1-2-3:
// Step 1. Include necessary header files such that the stuff your
// test logic needs is declared.
//
// Don't forget gtest.h, which declares the testing framework.
#include <limits.h>
#include "sample1.h"
#include <gtest/gtest.h>
// Step 2. Use the TEST macro to define your tests.
//
// TEST has two parameters: the test case name and the test name.
// After using the macro, you should define your test logic between a
// pair of braces. You can use a bunch of macros to indicate the
// success or failure of a test. EXPECT_TRUE and EXPECT_EQ are
// examples of such macros. For a complete list, see gtest.h.
//
// <TechnicalDetails>
//
// In Google Test, tests are grouped into test cases. This is how we
// keep test code organized. You should put logically related tests
// into the same test case.
//
// The test case name and the test name should both be valid C++
// identifiers. And you should not use underscore (_) in the names.
//
// Google Test guarantees that each test you define is run exactly
// once, but it makes no guarantee on the order the tests are
// executed. Therefore, you should write your tests in such a way
// that their results don't depend on their order.
//
// </TechnicalDetails>
// Tests Factorial().
// Tests factorial of negative numbers.
TEST(FactorialTest, Negative) {
// This test is named "Negative", and belongs to the "FactorialTest"
// test case.
EXPECT_EQ(1, Factorial(-5));
EXPECT_EQ(1, Factorial(-1));
EXPECT_TRUE(Factorial(-10) > 0);
// <TechnicalDetails>
//
// EXPECT_EQ(expected, actual) is the same as
//
// EXPECT_TRUE((expected) == (actual))
//
// except that it will print both the expected value and the actual
// value when the assertion fails. This is very helpful for
// debugging. Therefore in this case EXPECT_EQ is preferred.
//
// On the other hand, EXPECT_TRUE accepts any Boolean expression,
// and is thus more general.
//
// </TechnicalDetails>
}
// Tests factorial of 0.
TEST(FactorialTest, Zero) {
EXPECT_EQ(1, Factorial(0));
}
// Tests factorial of positive numbers.
TEST(FactorialTest, Positive) {
EXPECT_EQ(1, Factorial(1));
EXPECT_EQ(2, Factorial(2));
EXPECT_EQ(6, Factorial(3));
EXPECT_EQ(40320, Factorial(8));
}
// Tests IsPrime()
// Tests negative input.
TEST(IsPrimeTest, Negative) {
// This test belongs to the IsPrimeTest test case.
EXPECT_FALSE(IsPrime(-1));
EXPECT_FALSE(IsPrime(-2));
EXPECT_FALSE(IsPrime(INT_MIN));
}
// Tests some trivial cases.
TEST(IsPrimeTest, Trivial) {
EXPECT_FALSE(IsPrime(0));
EXPECT_FALSE(IsPrime(1));
EXPECT_TRUE(IsPrime(2));
EXPECT_TRUE(IsPrime(3));
}
// Tests positive input.
TEST(IsPrimeTest, Positive) {
EXPECT_FALSE(IsPrime(4));
EXPECT_TRUE(IsPrime(5));
EXPECT_FALSE(IsPrime(6));
EXPECT_TRUE(IsPrime(23));
}
// Step 3. Call RUN_ALL_TESTS() in main().
//
// We do this by linking in src/gtest_main.cc file, which consists of
// a main() function which calls RUN_ALL_TESTS() for us.
//
// This runs all the tests you've defined, prints the result, and
// returns 0 if successful, or 1 otherwise.
//
// Did you notice that we didn't register the tests? The
// RUN_ALL_TESTS() macro magically knows about all the tests we
// defined. Isn't this convenient?

// In this example, we use a more advanced feature of Google Test called
// test fixture.
//
// A test fixture is a place to hold objects and functions shared by
// all tests in a test case. Using a test fixture avoids duplicating
// the test code necessary to initialize and cleanup those common
// objects for each test. It is also useful for defining sub-routines
// that your tests need to invoke a lot.
//
// <TechnicalDetails>
//
// The tests share the test fixture in the sense of code sharing, not
// data sharing. Each test is given its own fresh copy of the
// fixture. You cannot expect the data modified by one test to be
// passed on to another test, which is a bad idea.
//
// The reason for this design is that tests should be independent and
// repeatable. In particular, a test should not fail as the result of
// another test's failure. If one test depends on info produced by
// another test, then the two tests should really be one big test.
//
// The macros for indicating the success/failure of a test
// (EXPECT_TRUE, FAIL, etc) need to know what the current test is
// (when Google Test prints the test result, it tells you which test
// each failure belongs to). Technically, these macros invoke a
// member function of the Test class. Therefore, you cannot use them
// in a global function. That's why you should put test sub-routines
// in a test fixture.

// Sometimes, more than one test cases may want to use the same or

"""Builds the Google Test (gtest) lib; this is for Windows projects
using SCons and can probably be easily extended for cross-platform
SCons builds. The compilation settings from your project will be used,
with some specific flags required for gtest added.
You should be able to call this file from more or less any SConscript
file.
You can optionally set a variable on the construction environment to
have the unit test executables copied to your output directory. The
variable should be env['EXE_OUTPUT'].
Another optional variable is env['LIB_OUTPUT']. If set, the generated
libraries are copied to the folder indicated by the variable.
If you place the gtest sources within your own project's source
directory, you should be able to call this SConscript file simply as
follows:
# -- cut here --
# Build gtest library; first tell it where to copy executables.
env['EXE_OUTPUT'] = '#/mybuilddir/mybuildmode' # example, optional
env['LIB_OUTPUT'] = '#/mybuilddir/mybuildmode/lib'
env.SConscript('whateverpath/gtest/scons/SConscript')
# -- cut here --
If on the other hand you place the gtest sources in a directory
outside of your project's source tree, you would use a snippet similar
to the following:
# -- cut here --
# The following assumes that $BUILD_DIR refers to the root of the
# directory for your current build mode, e.g. "#/mybuilddir/mybuildmode"
# Build gtest library; as it is outside of our source root, we need to

"""fuse_gtest_files.py v0.1.0
Fuses Google Test source code into a .h file and a .cc file.
SYNOPSIS
fuse_gtest_files.py [GTEST_ROOT_DIR] OUTPUT_DIR
Scans GTEST_ROOT_DIR for Google Test source code, and generates
two files: OUTPUT_DIR/gtest/gtest.h and OUTPUT_DIR/gtest/gtest-all.cc.
Then you can build your tests by adding OUTPUT_DIR to the include
search path and linking with OUTPUT_DIR/gtest/gtest-all.cc. These
two files contain everything you need to use Google Test. Hence
you can "install" Google Test by copying them to wherever you want.
GTEST_ROOT_DIR can be omitted and defaults to the parent directory
of the directory holding the fuse_gtest_files.py script.
EXAMPLES
./fuse_gtest_files.py fused_gtest
./fuse_gtest_files.py path/to/unpacked/gtest fused_gtest
This tool is experimental. In particular, it assumes that there is no
conditional inclusion of Google Test headers. Please report any
problems to googletestframework@googlegroups.com. You can read
http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide for
more information.

The `gtest-config' script provides access to the necessary compile and linking
flags to connect with Google C++ Testing Framework, both in a build prior to
installation, and on the system proper after installation. The installation
overrides may be issued in combination with any other queries, but will only
affect installation queries if called on a built but not installed gtest. The
installation queries may not be issued with any other types of queries, and
only one installation query may be made at a time. The version queries and
compiler flag queries may be combined as desired but not mixed. Different
version queries are always combined with logical "and" semantics, and only the
last of any particular query is used while all previous ones ignored. All
versions must be specified as a sequence of numbers separated by periods.
Compiler flag queries output the union of the sets of flags when combined.
Examples:
gtest-config --min-version=1.0 || echo "Insufficient Google Test version."
g++ $(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp
g++ $(gtest-config --ldflags --libs) -o foo foo.o
# When using a built but not installed Google Test:
g++ $(../../my_gtest_build/scripts/gtest-config ...) ...
# When using an installed Google Test, but with installation overrides:
export GTEST_PREFIX="/opt"
g++ $(gtest-config --libdir="/opt/lib64" ...) ...
Help:
--usage brief usage information
--help display this help message
Installation Overrides:
--prefix=<dir> overrides the installation prefix
--exec-prefix=<dir> overrides the executable installation prefix
--libdir=<dir> overrides the library installation prefix
--includedir=<dir> overrides the header file installation prefix
Installation Queries:
--prefix installation prefix
--exec-prefix executable installation prefix
--libdir library installation directory
--includedir header file installation directory
--version the version of the Google Test installation
Version Queries:
--min-version=VERSION return 0 if the version is at least VERSION
--exact-version=VERSION return 0 if the version is exactly VERSION
--max-version=VERSION return 0 if the version is at most VERSION
Compilation Flag Queries:
--cppflags compile flags specific to the C-like preprocessors
--cxxflags compile flags appropriate for C++ programs
--ldflags linker flags
--libs libraries for linking
