Designed with C++'s specifics in mind, Google C++ Mocking Framework (or Google Mock for short) is a library for writing and using C++ mock classes.

Inspired by jMock, EasyMock, and Hamcrest, and designed with C++'s specifics in mind, Google C++ Mocking Framework (or Google Mock for short) is a library for writing and using C++ mock classes.

Google Mock:

  • 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,
  • is extensible by users, and
  • works on Linux, Mac, OS X, Windows, Windows Mobile, minGW, and Symbian.
