pytest-flakes
=============

py.test plugin for efficiently checking python source with pyflakes.


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.

Simple usage example
-----------------------------

Consider you have this code::

    # content of module.py

    import os
    from os.path import *

    def some_function():
        pass

Running it with pytest-flakes installed shows two issues::

    $ py.test -q --flakes 
    F
    ================================= FAILURES =================================
    ______________________________ pyflakes-check ______________________________
    /tmp/doc-exec-685/module.py:2: UnusedImport
    'os' imported but unused
    /tmp/doc-exec-685/module.py:3: ImportStarUsed
    'from os.path import *' used; unable to detect undefined names
    1 failed in 0.00 seconds

These are only two of the many issues that pytest-flakes can find.

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 = ImportStarUsed

This would globally prevent complaints about star imports.
Rerunning with the above example will now look better::

    $ py.test -q --flakes
    F
    ================================= FAILURES =================================
    _________________ pyflakes-check(ignoring ImportStarUsed) __________________
    /tmp/doc-exec-685/module.py:2: UnusedImport
    'os' imported but unused
    1 failed in 0.00 seconds

But of course we still would want to delete the ``import os`` line to
have a clean pass.  

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


Ignoring certain lines in files
-------------------------------

You can ignore errors per line by appending special comments to them like this::

    import sys # noqa
    app # pragma: no flakes


Running pyflakes checks and no other tests
------------------------------------------

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

    py.test --flakes -m 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.

If you are using pytest < 2.4, then use the following invocation
to the same effect::

    py.test --flakes -k flakes


Notes
-----

The repository of this plugin is at https://github.com/fschulze/pytest-flakes

For more info on py.test see http://pytest.org

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