Thanks for considering contributing to Flask.
Please, don't use the issue tracker for this. Check whether the #pocoo
IRC
channel on Freenode can help with your issue. If your problem is not strictly
Werkzeug or Flask specific, #python
is generally more active.
StackOverflow is also worth considering.
- Under which versions of Python does this happen? This is even more important if your issue is encoding related.
- Under which versions of Werkzeug does this happen? Check if this issue is fixed in the repository.
- Include tests if your patch is supposed to solve a bug, and explain clearly under which circumstances the bug happens. Make sure the test fails without your patch.
- Try to follow PEP8, but you may ignore the line-length-limit if following it would make the code uglier.
You probably want to set up a virtualenv.
The minimal requirement for running the testsuite is py.test
. You can
install it with:
pip install pytest
Then you can run the testsuite with:
py.test
With only py.test installed, a large part of the testsuite will get skipped though. Whether this is relevant depends on which part of Werkzeug you're working on. Travis is set up to run the full testsuite when you submit your pull request anyways.
If you really want to test everything, you will have to install tox
instead
of pytest
. Currently we're depending on a development version of Tox
because the released version is missing features we absolutely need. You can
install it with:
pip install hg+https://bitbucket.org/hpk42/tox
The tox
command will then run all tests against multiple combinations
Python versions and dependency versions.
