Google C++ Testing Framework is Google's framework for writing C++ tests on a variety of platforms. It is based on the xUnit architecture, and it 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.
Google C++ Mocking Framework (or Google Mock for short) is a library for writing and using C++ mock classes. It was inspired by jMock, EasyMock, and Hamcrest, and designed with C++'s specifics in mind. It lets you create mock classes trivially using simple macros, supports a rich set of matchers and actions, handles unordered, partially ordered, or completely ordered expectations, and is extensible by users.
