We'd love to accept your patches! Before we can take them, we have to jump a couple of legal hurdles.
Please fill out either the individual or corporate Contributor License Agreement (CLA).
Follow either of the two links above to access the appropriate CLA and instructions for how to sign and return it. Once we receive it, we'll be able to accept your pull requests.
If you are a Googler, please make an attempt to submit an internal change rather than a GitHub Pull Request. If you are not able to submit an internal change a PR is acceptable as an alternative.
The Google Test community exists primarily through the discussion group and the GitHub repository. Likewise, the Google Mock community exists primarily through their own discussion group. You are definitely encouraged to contribute to the discussion and you can also help us to keep the effectiveness of the group high by following and promoting the guidelines listed here.
Showing courtesy and respect to others is a vital part of the Google culture, and we strongly encourage everyone participating in Google Test development to join us in accepting nothing less. Of course, being courteous is not the same as failing to constructively disagree with each other, but it does mean that we should be respectful of each other when enumerating the 42 technical reasons that a particular proposal may not be the best choice. There's never a reason to be antagonistic or dismissive toward anyone who is sincerely trying to contribute to a discussion.
Sure, C++ testing is serious business and all that, but it's also a lot of fun. Let's keep it that way. Let's strive to be one of the friendliest communities in all of open source.
As always, discuss Google Test in the official GoogleTest discussion group. You don't have to actually submit code in order to sign up. Your participation itself is a valuable contribution.
To keep the source consistent, readable, diffable and easy to merge, we use a fairly rigid coding style, as defined by the google-styleguide project. All patches will be expected to conform to the style outlined here. Use .clang-format to check your formatting.
If you plan to contribute a patch, you need to build Google Test, Google Mock, and their own tests from a git checkout, which has further requirements:
This section discusses how to make your own changes to the Google Test project.
To make sure your changes work as intended and don't break existing functionality, you'll want to compile and run Google Test and GoogleMock's own tests. For that you can use CMake:
mkdir mybuild
cd mybuild
cmake -Dgtest_build_tests=ON -Dgmock_build_tests=ON ${GTEST_REPO_DIR}
To choose between building only Google Test or Google Mock, you may modify your cmake command to be one of each
cmake -Dgtest_build_tests=ON ${GTEST_DIR} # sets up Google Test tests
cmake -Dgmock_build_tests=ON ${GMOCK_DIR} # sets up Google Mock tests
Make sure you have Python installed, as some of Google Test's tests are written
in Python. If the cmake command complains about not being able to find Python
(Could NOT find PythonInterp (missing: PYTHON_EXECUTABLE)
), try telling it
explicitly where your Python executable can be found:
cmake -DPYTHON_EXECUTABLE=path/to/python ...
Next, you can build Google Test and / or Google Mock and all desired tests. On *nix, this is usually done by
make
To run the tests, do
make test
All tests should pass.
