Google Test and Google Mock

Google Test, also known as GTest, is Google’s framework for writing unit tests in C++. It is widely recognized for its extensive testing capabilities and offers several notable features that facilitate comprehensive and efficient unit testing in C++. Among its key offerings are rich assertions, which enable developers to use a variety of assertions such as EXPECT_EQ and ASSERT_NE to compare expected outcomes with actual results, ensuring precise validation of test conditions. Furthermore, Google Test simplifies the management of common test configurations through test fixtures, which define setup and teardown operations, providing a consistent environment for each test.
