But maybe you think that writing all those main() functions is too much work? We agree with you completely and that's why Google Test provides a basic implementation of main(). If it fits your needs, then just link your test with gtest_main library and you are good to go.
== Important note for Visual C++ users ==
If you put your tests into a library and your `main()` function is in a different library or in your .exe file, those tests will not run. To prevent this from happening, use the `/OPT:NOREF` linker option. If you use MSVC++ IDE, go to your .exe project properties/Configuration Properties/Linker/Optimization and set References setting to `Keep Unreferenced Data (/OPT:NOREF)`. What happens is, when you define your tests, Google Test creates certain static objects to represent them. These objects are not referenced from elsewhere but their constructors are still supposed to run. When Visual C++ linker sees that nothing in the library is referenced from other places it throws the library out. The `/OPT:NOREF` option forces it to keep unreferenced libraries.

Congratulations! You've learned the Google Test basics. You can start writing
