pytest-flake8 0.9

pytest plugin to check FLAKE8 requirements

Usage

Install by running the command:

pip install pytest-flake8

After installing it, when you run tests with the option:

py.test --flake8

every file ending in .py will be discovered and checked with flake8.

Note

If optional flake8 plugins are installed, those will be used automatically. No provisions have been made for configuring these via py.test.

Warning

Running flake8 tests on your project is likely to cause a number of issues. The plugin allows one to configure on a per-project and per-file basis which errors or warnings to ignore, see flake8-ignore.

Configuring FLAKE8 options per project and file

Maximum line length can be configured for the whole project by adding a flake8-max-line-length option to your setup.cfg or tox.ini file like this:

# content of setup.cfg
[pytest]
flake8-max-line-length = 99

Note that the default will be what naturally comes with flake8 (which it turn gets its default from pep8).

You may configure flake8-checking options for your project by adding an flake8-ignore entry to your setup.cfg or tox.ini file like this:

# content of setup.cfg
[pytest]
flake8-ignore = E201 E231

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

$ py.test -q  --flake8
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 flake8-ignore line with a glob-pattern and a space-separated list of codes:

# content of setup.cfg
[pytest]
flake8-ignore =
    *.py E201
    doc/conf.py ALL

So if you have a conf.py like this:

# content of doc/conf.py

func (  [1,2,3]) #this line lots pep8 errors :)

then running again with the previous example will show a single failure and it will ignore doc/conf.py alltogether:

$ py.test --flake8 -v # verbose shows what is ignored
