Pytest development of the core, some plugins and support code happens in repositories living under:
All pytest-dev Contributors team members have write access to all contained repositories. pytest core and plugins are generally developed using pull requests to respective repositories.
You can submit your plugin by subscribing to the pytest-dev mail list and writing a mail pointing to your existing pytest plugin repository which must have the following:
- PyPI presence with a
setup.pythat contains a license,pytest-prefixed, version number, authors, short and long description. - a
tox.inifor running tests using tox. - a
README.txtdescribing how to use the plugin and on which platforms it runs. - a
LICENSE.txtfile or equivalent containing the licensing information, with matching info insetup.py. - an issue tracker unless you rather want to use the core
pytestissue tracker.
If no contributor strongly objects and two agree, the repo will be
transferred to the pytest-dev organisation and you'll become a
member of the pytest-dev Contributors team, with commit rights
to all projects. We recommend that each plugin has at least three
people who have the right to release to pypi.
Report bugs for pytest at https://github.com/pytest-dev/pytest/issues
If you are reporting a bug, please include:
- Your operating system name and version.
- Any details about your local setup that might be helpful in troubleshooting, specifically Python interpreter version, installed libraries and pytest version.
- Detailed steps to reproduce the bug.
If you can write a demonstration test that currently fails but should pass (xfail), that is a very useful commit to make as well, even if you can't find how to fix the bug yet.
Do you like pytest? Share some love on Twitter or in your blog posts!
We'd also like to hear about your propositions and suggestions. Feel free to submit them as issues and:
- Set the "kind" to "enhancement" or "proposal" so that we can quickly find about them.
- Explain in detail how they should work.
- Keep the scope as narrow as possible. This will make it easier to implement.
- If you have required skills and/or knowledge, we are very happy for :ref:`pull requests <pull-requests>`.
Look through the GitHub issues for bugs. Here is sample filter you can use: https://github.com/pytest-dev/pytest/labels/bug
:ref:`Talk <contact>` to developers to find out how you can fix specific bugs.
Don't forget to check the issue trackers of your favourite plugins, too!
Look through the GitHub issues for enhancements. Here is sample filter you can use: https://github.com/pytest-dev/pytest/labels/enhancement
:ref:`Talk <contact>` to developers to find out how you can implement specific features.
pytest could always use more documentation. What exactly is needed?
- More complementary documentation. Have you perhaps found something unclear?
- Documentation translations. We currently have only English.
- Docstrings. There can never be too many of them.
- Blog posts, articles and such -- they're all very appreciated.
You can also edit documentation files directly in the Github web interface without needing to make a fork and local copy. This can be convenient for small fixes.
Note
What is a "pull request"? It informs project's core developers about the changes you want to review and merge. Pull requests are stored on GitHub servers. Once you send pull request, we can discuss it's potential modifications and even add more commits to it later on.
There's an excellent tutorial on how Pull Requests work in the GitHub Help Center, but here is a simple overview:
Fork the pytest GitHub repository. It's fine to use
pytestas your fork repository name because it will live under your user.Clone your fork locally using git and create a branch:
$ git clone [email protected]:YOUR_GITHUB_USERNAME/pytest.git $ cd pytest # now, to fix a bug create your own branch off "master": $ git checkout -b your-bugfix-branch-name master # or to instead add a feature create your own branch off "features": $ git checkout -b your-feature-branch-name features
Given we have "major.minor.micro" version numbers, bugfixes will usually be released in micro releases whereas features will be released in minor releases and incompatible changes in major releases.

Install tox
Tox is used to run all the tests and will automatically setup virtualenvs to run the tests in. (will implicitly use http://www.virtualenv.org/en/latest/):
$ pip install tox
Run all the tests
You need to have Python 2.7 and 3.5 available in your system. Now running tests is as simple as issuing this command:
$ python runtox.py -e py27,py35,flakes
This command will run tests via the "tox" tool against Python 2.7 and 3.5 and also perform "flakes" coding-style checks.
runtox.pyis a thin wrapper aroundtoxwhich installs from a development package index where newer (not yet released to pypi) versions of dependencies (especiallypy) might be present.You can now edit your local working copy.
You can now make the changes you want and run the tests again as necessary.
To run tests on py27 and pass options to pytest (e.g. enter pdb on failure) to pytest you can do:
$ python runtox.py -e py27 -- --pdb
or to only run tests in a particular test module on py35:
$ python runtox.py -e py35 -- testing/test_config.py
Commit and push once your tests pass and you are happy with your change(s):
$ git commit -a -m "<commit message>" $ git push -u
Make sure you add a CHANGELOG message, and add yourself to AUTHORS. If you are unsure about either of these steps, submit your pull request and we'll help you fix it up.
Finally, submit a pull request through the GitHub website using this data:
head-fork: YOUR_GITHUB_USERNAME/pytest compare: your-branch-name base-fork: pytest-dev/pytest base: master # if it's a bugfix base: feature # if it's a feature
