Usage
-----

Install by running the command::

    pip install pytest-flake8

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

    pytest --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 `pytest`_.

.. 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_.

.. _flake8-ignore:

Configuring FLAKE8 options per project and file
-----------------------------------------------

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

    # content of setup.cfg
    [tool:pytest]
    flake8-max-line-length = 99
    flake8-max-doc-length = 74

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

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
    [tool:pytest]
    flake8-ignore = E201 E231

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

    $ pytest -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
    [tool: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 altogether::

    $ pytest --flake8 -v # verbose shows what is ignored

Note that doc/conf.py was not considered or imported.

FAQs
-----

All the flake8 tests are skipping!
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This is by design.  Clean flake8 results are cached and, unless the file is modified, not tested again.

You can run with ``pytest --cache-clear --flake8`` to override this.
