1# Googletest Mocking (gMock) Framework 2 3### Overview 4 5Google's framework for writing and using C++ mock classes. It can help you 6derive better designs of your system and write better tests. 7 8It is inspired by: 9 10* [jMock](http://www.jmock.org/) 11* [EasyMock](https://easymock.org/) 12* [Hamcrest](https://code.google.com/p/hamcrest/) 13 14It is designed with C++'s specifics in mind. 15 16gMock: 17 18- Provides a declarative syntax for defining mocks. 19- Can define partial (hybrid) mocks, which are a cross of real and mock 20 objects. 21- Handles functions of arbitrary types and overloaded functions. 22- Comes with a rich set of matchers for validating function arguments. 23- Uses an intuitive syntax for controlling the behavior of a mock. 24- Does automatic verification of expectations (no record-and-replay needed). 25- Allows arbitrary (partial) ordering constraints on function calls to be 26 expressed. 27- Lets a user extend it by defining new matchers and actions. 28- Does not use exceptions. 29- Is easy to learn and use. 30 31Details and examples can be found here: 32 33* [gMock for Dummies](https://google.github.io/googletest/gmock_for_dummies.html) 34* [Legacy gMock FAQ](https://google.github.io/googletest/gmock_faq.html) 35* [gMock Cookbook](https://google.github.io/googletest/gmock_cook_book.html) 36* [gMock Cheat Sheet](https://google.github.io/googletest/gmock_cheat_sheet.html) 37 38GoogleMock is a part of 39[GoogleTest C++ testing framework](https://github.com/google/googletest/) and a 40subject to the same requirements. 41
