Contributions are highly welcomed and appreciated.  Every little help counts,
so do not hesitate!

Types of contributions
======================

Submit feedback for developers
------------------------------

Do you like py.test?  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 `here <https://bitbucket.org/hpk42/pytest/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, you can always contribute to
  these issues!

Report bugs
-----------

Report bugs at https://bitbucket.org/hpk42/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 py.test version.
* Detailed steps to reproduce the bug.

Fix bugs
--------

Look through the BitBucket issues for bugs.  Here is sample filter you can use:
https://bitbucket.org/hpk42/pytest/issues?status=new&status=open&kind=bug

:ref:`Talk <contact>` to developers to find out how you can fix specific bugs.

Implement features
------------------

Look through the BitBucket issues for enhancements.  Here is sample filter you
can use:
https://bitbucket.org/hpk42/pytest/issues?status=new&status=open&kind=enhancement

:ref:`Talk <contact>` to developers to find out how you can implement specific
features.

Write documentation
-------------------

py.test could always use more documentation.  What exactly is needed?

* More complementary documentation.  Have you perhaps found something unclear?
* Documentation translations.  We currently have English and Japanese versions.
* Docstrings.  There's never too much of them.
* Blog posts, articles and such -- they're all very appreciated.

Getting started for contributing
================================

The primary development platform for py.test is BitBucket.  You can find all
the issues there and submit pull requests.  There is, however,
a `GitHub mirror <https://github.com/hpk42/pytest/>`__ available, too,
although it only allows for submitting pull requests.  For a GitHub
contribution guide look :ref:`below <contribution-on-github>`.

1. Fork the py.test `repository <https://bitbucket.org/hpk42/pytest>`__ on BitBucket.

2. Create a local virtualenv (http://www.virtualenv.org/en/latest/)::

    $ virtualenv pytest-venv
    $ cd pytest-venv/
    $ source bin/activate

.. _checkout:

3. Clone your fork locally::

    $ hg clone ssh://hg@bitbucket.org/your_name_here/pytest

.. _installing-dev-pytest:

4. Install your local copy into a virtualenv::

    $ cd pytest/
    $ python setup.py develop

   If that last command complains about not finding the required version
   of "py" then you need to use the development pypi repository::

    $ python setup.py develop -i http://pypi.testrun.org

.. _testing-pytest:

5. When you're done making changes, check that all of them pass all the tests
   (including PEP8 and different Python interpreter versions).  First install
   ``tox``::

    $ pip install tox

  You also need to have Python 2.7 and 3.3 available in your system.  Now
  running tests is as simple as issuing this one command::

    $ tox -e py27,py33

  This command will run tests for both Python 2.7 and 3.3, which is a minimum
  required to get your patch merged.  To run whole test suit issue::

    $ tox

6. Commit your changes and push to BitBucket::

    $ hg branch <yourbranchname>
    $ hg add .
    $ hg commit -m"<commit message>
    $ hg push -b .

7. Submit a pull request through the BitBucket website.

What about GitHub?
------------------

.. warning::
  Remember that GitHub is **not** a default development platform for py.test
  and it doesn't include e.g. issue list.

1. Fork the py.test `repository <https://github.com/hpk42/pytest/>`__ on GitHub.

2. Create a local virtualenv (http://www.virtualenv.org/en/latest/)::

    $ virtualenv pytest-venv
    $ cd pytest-venv/

3. Clone your fork locally::

    $ git clone git@github.com:your_name_here/pytest.git

4. :ref:`Install your local copy into a virtualenv <installing-dev-pytest>`
   and after that :ref:`test your changes <testing-pytest>`.

5. Commit your changes and push to GitHub::

    $ git branch <yourbranchname>
    $ git checkout <yourbranchname>
    $ git add .
    $ git commit -am"<commit message>"
    $ git push origin <yourbranchname>

6. Submit a pull request through the GitHub website.
