7Welcome to **Google Test**, Google's C++ test framework!
8
9This repository is a merger of the formerly separate GoogleTest and
10GoogleMock projects. These were so closely related that it makes sense to
11maintain and release them together.
12
13Please see the project page above for more information as well as the
14mailing list for questions, discussions, and development. There is
15also an IRC channel on [OFTC](https://webchat.oftc.net/) (irc.oftc.net) #gtest available. Please
16join us!
17
18Getting started information for **Google Test** is available in the
19[Google Test Primer](googletest/docs/Primer.md) documentation.
20
21**Google Mock** is an extension to Google Test for writing and using C++ mock
22classes. See the separate [Google Mock documentation](googlemock/README.md).
23
24More detailed documentation for googletest (including build instructions) are
25in its interior [googletest/README.md](googletest/README.md) file.

27## Features ##
28
29 * An [xUnit](https://en.wikipedia.org/wiki/XUnit) test framework.
30 * Test discovery.
31 * A rich set of assertions.
32 * User-defined assertions.
33 * Death tests.
34 * Fatal and non-fatal failures.
35 * Value-parameterized tests.
36 * Type-parameterized tests.
37 * Various options for running the tests.
38 * XML test report generation.
39
40## Platforms ##
41
42Google test has been used on a variety of platforms:
43
44 * Linux
45 * Mac OS X
46 * Windows
47 * Cygwin
48 * MinGW
49 * Windows Mobile
50 * Symbian
51
52## Who Is Using Google Test? ##
53
54In addition to many internal projects at Google, Google Test is also used by
55the following notable projects:
56
57 * The [Chromium projects](http://www.chromium.org/) (behind the Chrome
58 browser and Chrome OS).
59 * The [LLVM](http://llvm.org/) compiler.
60 * [Protocol Buffers](https://github.com/google/protobuf), Google's data
61 interchange format.
62 * The [OpenCV](http://opencv.org/) computer vision library.
63 * [tiny-dnn](https://github.com/tiny-dnn/tiny-dnn): header only, dependency-free deep learning framework in C++11.

65## Related Open Source Projects ##
66
67[GTest Runner](https://github.com/nholthaus/gtest-runner) is a Qt5 based automated test-runner and Graphical User Interface with powerful features for Windows and Linux platforms.
68
69[Google Test UI](https://github.com/ospector/gtest-gbar) is test runner that runs
70your test binary, allows you to track its progress via a progress bar, and
71displays a list of test failures. Clicking on one shows failure text. Google
72Test UI is written in C#.
73
74[GTest TAP Listener](https://github.com/kinow/gtest-tap-listener) is an event
75listener for Google Test that implements the
76[TAP protocol](https://en.wikipedia.org/wiki/Test_Anything_Protocol) for test
77result output. If your test runner understands TAP, you may find it useful.
78
79[gtest-parallel](https://github.com/google/gtest-parallel) is a test runner that
80runs tests from your binary in parallel to provide significant speed-up.
81
82## Requirements ##
83
84Google Test is designed to have fairly minimal requirements to build
85and use with your projects, but there are some. Currently, we support
86Linux, Windows, Mac OS X, and Cygwin. We will also make our best
87effort to support other platforms (e.g. Solaris, AIX, and z/OS).
88However, since core members of the Google Test project have no access
89to these platforms, Google Test may have outstanding issues there. If
90you notice any problems on your platform, please notify
91[googletestframework@googlegroups.com](https://groups.google.com/forum/#!forum/googletestframework). Patches for fixing them are
92even more welcome!
93
94### Linux Requirements ###
95
96These are the base requirements to build and use Google Test from a source
97package (as described below):
98
99 * GNU-compatible Make or gmake
100 * POSIX-standard shell
101 * POSIX(-2) Regular Expressions (regex.h)
102 * A C++98-standard-compliant compiler
103
104### Windows Requirements ###
105
106 * Microsoft Visual C++ 2010 or newer
107
108### Cygwin Requirements ###
109
110 * Cygwin v1.5.25-14 or newer
111
112### Mac OS X Requirements ###
113
114 * Mac OS X v10.4 Tiger or newer
115 * Xcode Developer Tools
116
117### Requirements for Contributors ###
118
119We welcome patches. If you plan to contribute a patch, you need to
120build Google Test and its own tests from a git checkout (described
121below), which has further requirements:
122
123 * [Python](https://www.python.org/) v2.3 or newer (for running some of
124 the tests and re-generating certain source files from templates)
125 * [CMake](https://cmake.org/) v2.6.4 or newer
126
127## Regenerating Source Files ##
128
129Some of Google Test's source files are generated from templates (not
130in the C++ sense) using a script.
131For example, the
132file include/gtest/internal/gtest-type-util.h.pump is used to generate
133gtest-type-util.h in the same directory.
134
135You don't need to worry about regenerating the source files
136unless you need to modify them. You would then modify the
137corresponding `.pump` files and run the '[pump.py](googletest/scripts/pump.py)'
138generator script. See the [Pump Manual](googletest/docs/PumpManual.md).
139
140### Contributing Code ###
141
142We welcome patches. Please read the
143[Developer's Guide](googletest/docs/DevGuide.md)
144for how you can contribute. In particular, make sure you have signed
145the Contributor License Agreement, or we won't be able to accept the
146patch.
147
148Happy testing!
