Google Test has recently (02/09/2018) switched the default death test
style from "fast" to "threadsafe" in
ec7faa943d
Threadsafe death tests have been used internally for a while, and are
proven to be a better default.
However, adopting this better default can be challenging for large
projects with a significant investment in custom infrastructure built on
top of Google Test. The same custom infrastructure can make it difficult
for large projects to switch back to the old default by passing in
--gtest_death_test_style=fast.
For the reasons above, the default switch is considered too disruptive,
and this CL reverts it. This CL also introduces the
GTEST_DEFAULT_DEATH_TEST_STYLE preprocesor macro, which replaces the
hard-coded default. The macro can be defined in
gtest/internal/custom/gtest-port.h by projects that are ready to migrate
to thread-safe death tests.
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.
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 documentation.
Google Mock is an extension to Google Test for writing and using C++ mock classes. See the separate Google Mock documentation.
More detailed documentation for googletest (including build instructions) are in its interior googletest/README.md file.
Features
- An 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 (behind the Chrome browser and Chrome OS).
- The LLVM compiler.
- Protocol Buffers, Google's data interchange format.
- The OpenCV computer vision library.
- tiny-dnn: header only, dependency-free deep learning framework in C++11.
Related Open Source Projects
GTest Runner is a Qt5 based automated test-runner and Graphical User Interface with powerful features for Windows and Linux platforms.
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.
gtest-parallel is a test runner that runs tests from your binary in parallel to provide significant speed-up.
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 googletestframework@googlegroups.com. 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++ 2015 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
