Google's C++ testing framework based on xUnit that runs on multiple platforms.

GoogleTest is an open source unit testing framework developed by Google. It also supports unit testing of C code.

GTest (as it is commonly known) supports various platforms including Linux, OS X, Windows and Symbian. It provides basic unit testing features in the xUnit model in the form ASSERT_EQ() or EXPECT_EQ(), with automatic test registration. It also provides advanced features such as death tests, shuffling and sharding of tests, and Hudson/Jenkins-compatible XML output.

GTest integrates well with gmock, a C++ mocking framework.

There are three GTest related open source projects which can enhance the GTest user experience:

  1. Google Test UI - provides a GUI for running gtest binary and displaying the results.
  2. GTest TAP listener - Event listener for GTest based on TAP, for test result output.
  3. gtpp - Google Test Pretty Printer, offering shorter and clearer console test output
