[![Build status](https://ci.appveyor.com/api/projects/status/4o38plt0xbo1ubc8/branch/master?svg=true)](https://ci.appveyor.com/project/BillyDonahue/googletest/branch/master)

Welcome to **Google Test**, Google's C++ test framework!

This repository is a merger of the formerly separate GoogleTest and

GoogleMock projects. These were so closely related that it makes sense to

maintain and release them together.

Please see the project page above for more information as well as the

mailing list for questions, discussions, and development.  There is

also an IRC channel on OFTC (irc.oftc.net) #gtest available.  Please

join us!

Getting started information for **Google Test** is available in the

[Google Test Primer](googletest/docs/Primer.md) documentation.

**Google Mock** is an extension to Google Test for writing and using C++ mock

classes.  See the separate [Google Mock documentation](googlemock/README.md).

More detailed documentation for googletest (including build instructions) are

in its interior [googletest/README.md](googletest/README.md) file.

## Features ##

  * An [XUnit](https://en.wikipedia.org/wiki/XUnit) test framework.

  * Test discovery.

  * A rich set of assertions.

  * User-defined assertions.

  * Death tests.

  * Fatal and non-fatal failures.

  * Value-parameterized tests.

  * Type-parameterized tests.

  * Various options for running the tests.

  * XML test report generation.

## Platforms ##

Google test has been used on a variety of platforms:

  * Linux

  * Mac OS X

  * Windows

  * Cygwin

  * MinGW

  * Windows Mobile

  * Symbian

## 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](https://github.com/google/protobuf), Google's data

    interchange format.

  * The [OpenCV](http://opencv.org/) computer vision library.

## Related Open Source Projects ##

[Google Test UI](https://github.com/ospector/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](https://en.wikipedia.org/wiki/Test_Anything_Protocol) for test

result output. If your test runner understands TAP, you may find it useful.

## Requirements ##

Google Test is designed to have fairly minimal requirements to build

and use with your projects, but there are some.  Currently, we support

Linux, Windows, Mac OS X, and Cygwin.  We will also make our best

effort to support other platforms (e.g. Solaris, AIX, and z/OS).

However, since core members of the Google Test project have no access

to these platforms, Google Test may have outstanding issues there.  If

you notice any problems on your platform, please notify

. Patches for fixing them are

even more welcome!

### Linux Requirements ###

These are the base requirements to build and use Google Test from a source

package (as described below):

  * GNU-compatible Make or gmake

  * POSIX-standard shell

  * POSIX(-2) Regular Expressions (regex.h)

  * A C++98-standard-compliant compiler

### Windows Requirements ###

  * Microsoft Visual C++ v7.1 or newer

### Cygwin Requirements ###

  * Cygwin v1.5.25-14 or newer

### Mac OS X Requirements ###

  * Mac OS X v10.4 Tiger or newer

  * Xcode Developer Tools

### Requirements for Contributors ###

We welcome patches.  If you plan to contribute a patch, you need to

build Google Test and its own tests from a git checkout (described

below), which has further requirements:

  * [Python](https://www.python.org/) v2.3 or newer (for running some of

    the tests and re-generating certain source files from templates)

  * [CMake](https://cmake.org/) v2.6.4 or newer

## Regenerating Source Files ##

Some of Google Test's source files are generated from templates (not

in the C++ sense) using a script.

For example, the

file include/gtest/internal/gtest-type-util.h.pump is used to generate

gtest-type-util.h in the same directory.

You don't need to worry about regenerating the source files

unless you need to modify them.  You would then modify the

corresponding `.pump` files and run the '[pump.py](googletest/scripts/pump.py)'

generator script.  See the [Pump Manual](googletest/docs/PumpManual.md).

### Contributing Code ###

We welcome patches.  Please read the

[Developer's Guide](googletest/docs/DevGuide.md)

for how you can contribute. In particular, make sure you have signed

the Contributor License Agreement, or we won't be able to accept the

patch.

Happy testing!
