Google Test

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.

Google Test conforms to the XUnit test framework pattern. It features:

• 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 (behind the Chrome browser and Chrome OS).
• The LLVM compiler.
• Protocol Buffers, Google's data interchange format.
• The OpenCV computer vision library.

Related Open Source Projects

Google Test UI 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 is an event listener for Google Test that implements the TAP protocol for test result output. If your test runner understands TAP, you may find it useful.

About Google Mock

Google Mock is an extension to Google Test for writing and using C++ mock classes. It is inspired by jMock, EasyMock, and Hamcrest, and designed with C++'s specifics in mind.

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.

We hope you find it useful!

Using Google Mock Without Google Test

Google Mock is not a testing framework itself. Instead, it needs a testing framework for writing tests. Google Mock works seamlessly with Google Test, butj you can also use it with any C++ testing framework.

Getting Started

If you are new to the project, we suggest that you read the user documentation in the following order:

• Learn the basics of Google Test, if you choose to use Google Mock with it (recommended).
• Read Google Mock for Dummies.
• Read the instructions on how to build Google Mock.

You can also watch Zhanyong's talk 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.

Regenerating Source Files

Some of Google Test's source files are generated from templates (not in the C++ sense) using a script. A template file is named FOO.pump, where FOO is the name of the file it will generate. 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' generator script. See the Pump Manual.

Contributing Code

We welcome patches. Please read the Developer's Guide 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!
