Googletest Mocking (gMock) Framework

Overview

Google's framework for writing and using C++ mock classes. It can help you derive better designs of your system and write better tests.

It is inspired by:

• jMock,
• EasyMock, and
• Hamcrest,

and designed with C++'s specifics in mind.

gMock:

• provides a declarative syntax for defining mocks,
• can define partial (hybrid) mocks, which are a cross of real and mock objects,
• handles functions of arbitrary types and overloaded functions,
• comes with a rich set of matchers for validating function arguments,
• uses an intuitive syntax for controlling the behavior of a mock,
• does automatic verification of expectations (no record-and-replay needed),
• allows arbitrary (partial) ordering constraints on function calls to be expressed,
• lets a user extend it by defining new matchers and actions.
• does not use exceptions, and
• is easy to learn and use.

Details and examples can be found here:

• [gMock for Dummies](docs/for_dummies.md)
• [Legacy gMock FAQ](docs/gmock_faq.md)
• [gMock Cookbook](docs/cook_book.md)
• [gMock Cheat Sheet](docs/cheat_sheet.md)

Google Mock is a part of Google Test C++ testing framework and a subject to the same requirements.
