Inspired by [jMock](http://www.jmock.org/), [EasyMock](http://www.easymock.org/), and [Hamcrest](http://code.google.com/p/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.
We hope you find it useful!
## Who are using Google Mock? ##
We have enjoyed using Google Mock in many projects at Google. Outside of Google, the most notable client is probably the [Chromium projects](http://www.chromium.org/) (behind the Chrome browser and Chrome OS). If you know of a project that's using Google Mock and want it to be listed here, please let
`googlemock@googlegroups.com` know.
## System Requirements ##
Google Mock is not a testing framework itself. Instead, it needs a
testing framework for writing tests. Google Mock works seamlessly
with [Google Test](http://code.google.com/p/googletest/). It comes
with a copy of Google Test bundled. Starting with version 1.1.0,
you can also use it with [any C++ testing framework of your choice](ForDummies#Using_Google_Mock_with_Any_Testing_Framework.md).
Google Mock has been tested with **gcc 4.0+** and **Microsoft Visual C++ 8.0 SP1**. Users
reported that it also works with **gcc 3.4**, **Microsoft Visual C++ 7.1**, and **Cygwin**, although we haven't tested it there ourselves.
## Getting Started ##
If you are new to the project, we suggest to read the user
documentation in the following order:
* Learn the [basics](http://code.google.com/p/googletest/wiki/Primer) of Google Test, if you choose to use Google Mock with it (recommended).
* Read [Google Mock for Dummies](ForDummies.md).
* Read the instructions on how to [build Google Mock](http://code.google.com/p/googlemock/source/browse/trunk/README).
You can also watch Zhanyong's [talk](http://www.youtube.com/watch?v=sYpCyLI47rM) on Google Mock's usage and implementation.
Once you understand the basics, check out the rest of the docs:
* CheatSheet - all the commonly used stuff at a glance.
* CookBook - recipes for getting things done, including advanced techniques.
If you need help, please check the KnownIssues and FrequentlyAskedQuestions before
posting a question on the [googlemock](http://groups.google.com/group/googlemock)
discussion group.
We'd love to have your help! Please
read the DevGuide if you are willing to contribute to the development.
Google's framework for writing C++ tests on a variety of platforms
(Linux, Mac OS X, Windows, Cygwin, Windows CE, and Symbian). Based on
the xUnit architecture. Supports automatic test discovery, a rich set
of assertions, user-defined assertions, death tests, fatal and
non-fatal failures, value- and type-parameterized tests, various
options for running the tests, and XML test report generation.
## Getting Started ##
After downloading Google Test, unpack it, read the README file and the documentation wiki pages (listed on the right side of this front page).
## Who Is Using Google Test? ##
In addition to many internal projects at Google, Google Test is also used by
the following notable projects:
* The [Chromium projects](http://www.chromium.org/) (behind the Chrome browser and Chrome OS)
* The [LLVM](http://llvm.org/) compiler
* [Protocol Buffers](http://code.google.com/p/protobuf/) (Google's data interchange format)
* The [OpenCV](http://opencv.org/) computer vision library

## Google Test-related open source projects ##
[Google Test UI](http://code.google.com/p/gtest-gbar/) is test runner that runs your test binary, allows you to track its progress via a progress bar, and displays a list of test failures. Clicking on one shows failure text. Google Test UI is written in C#.
[GTest TAP Listener](https://github.com/kinow/gtest-tap-listener) is an event listener for Google Test that implements the [TAP protocol](http://en.wikipedia.org/wiki/Test_Anything_Protocol) for test result output. If your test runner understands TAP, you may find it useful.
