pytest-flakes 0.1

Usage

install via:

pip install pytest-flakes

if you then type:

py.test --flakes

every file ending in .py will be discovered and run through pyflakes, starting from the command line arguments.

Configuring pyflakes options per project and file

You may configure pyflakes-checking options for your project by adding an flakes-ignore entry to your setup.cfg or setup.cfg file like this:

# content of setup.cfg
[pytest]
flakes-ignore = UnusedImport

This would globally prevent complaints about two whitespace issues. Rerunning with the above example will now look better:

$ py.test -q --flakes
collecting ... collected 1 items
.
1 passed in 0.01 seconds

If you have some files where you want to specifically ignore some errors or warnings you can start a flakes-ignore line with a glob-pattern and a space-separated list of codes:

# content of setup.cfg
[pytest]
flakes-ignore =
    *.py UnusedImport
    doc/conf.py ALL

Running pyflakes checks and no other tests

You can also restrict your test run to only perform “flakes” tests and not any other tests by typing:

py.test --flakes -k flakes

This will only run tests that are marked with the “flakes” keyword which is added for the flakes test items added by this plugin.

The code is partially based on Ronny Pfannschmidt’s pytest-codecheckers plugin and Holger Krekel’s pytest-pep8.
