# GoogleTest



### Announcements



#### Live at Head



GoogleTest now follows the

[Abseil Live at Head philosophy](https://abseil.io/about/philosophy#upgrade-support).

We recommend

[updating to the latest commit in the `main` branch as often as possible](https://github.com/abseil/abseil-cpp/blob/master/FAQ.md#what-is-live-at-head-and-how-do-i-do-it).

We do publish occasional semantic versions, tagged with

`v${major}.${minor}.${patch}` (e.g. `v1.15.2`).



#### Documentation Updates



Our documentation is now live on GitHub Pages at

https://google.github.io/googletest/. We recommend browsing the documentation on

GitHub Pages rather than directly in the repository.



#### Release 1.15.2



[Release 1.15.2](https://github.com/google/googletest/releases/tag/v1.15.2) is

now available.



The 1.15.x branch requires at least C++14.



#### Continuous Integration



We use Google's internal systems for continuous integration.



#### Coming Soon



*   We are planning to take a dependency on

    [Abseil](https://github.com/abseil/abseil-cpp).



## Welcome to **GoogleTest**, 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.



### Getting Started



See the [GoogleTest User's Guide](https://google.github.io/googletest/) for

documentation. We recommend starting with the

[GoogleTest Primer](https://google.github.io/googletest/primer.html).



More information about building GoogleTest can be found at

[googletest/README.md](googletest/README.md).



## Features



*   xUnit test framework: \

    Googletest is based on the [xUnit](https://en.wikipedia.org/wiki/XUnit)

    testing framework, a popular architecture for unit testing

*   Test discovery: \

    Googletest automatically discovers and runs your tests, eliminating the need

    to manually register your tests

*   Rich set of assertions: \

    Googletest provides a variety of assertions, such as equality, inequality,

    exceptions, and more, making it easy to test your code

*   User-defined assertions: \

    You can define your own assertions with Googletest, making it simple to

    write tests that are specific to your code

*   Death tests: \

    Googletest supports death tests, which verify that your code exits in a

    certain way, making it useful for testing error-handling code

*   Fatal and non-fatal failures: \

    You can specify whether a test failure should be treated as fatal or

    non-fatal with Googletest, allowing tests to continue running even if a

    failure occurs

*   Value-parameterized tests: \

    Googletest supports value-parameterized tests, which run multiple times with

    different input values, making it useful for testing functions that take

    different inputs

*   Type-parameterized tests: \

    Googletest also supports type-parameterized tests, which run with different

    data types, making it useful for testing functions that work with different

    data types

*   Various options for running tests: \

    Googletest provides many options for running tests including running

    individual tests, running tests in a specific order and running tests in

    parallel



## Supported Platforms



GoogleTest follows Google's

[Foundational C++ Support Policy](https://opensource.google/documentation/policies/cplusplus-support).

See

[this table](https://github.com/google/oss-policies-info/blob/main/foundational-cxx-support-matrix.md)

for a list of currently supported versions of compilers, platforms, and build

tools.



## Who Is Using GoogleTest?



In addition to many internal projects at Google, GoogleTest is also used by the

following notable projects:



*   The [Chromium projects](https://www.chromium.org/) (behind the Chrome

    browser and Chrome OS).

*   The [LLVM](https://llvm.org/) compiler.

*   [Protocol Buffers](https://github.com/google/protobuf), Google's data

    interchange format.

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