Frequently Asked Questions about GoogleTest

There are numerous Frequently Asked Questions(FAQ) about GoogleTest, this section tries to answer some of them briefly.

GoogleTest is a framework that is used to write test suites in C++ code. It was developed by testing team of Google.

Underscores (_) in C++ are special reserve keyword used by the compiler and the standard library of C++ programming language. Hence, test suite and test names should not contain underscores.

You can use either typed tests or value-parameterized tests for testing different implementations of an interface. Write typed tests when instances of the different implementations are created the same way. And, write value-parameterized tests when you need different code patterns to create instances of the implementations.

Yes, you can derive test fixture from another. To share a fixture among different test suites, create a base test fixture class with the shared logic and then derive a separate fixture class for each test suite that requires the common logic.

The testing services in GoogleTest reads the return value of RUN_ALL_TESTS() in order to determine whether a test has passed or not. So, always use the return keyword with RUN_ALL_TESTS().
