pytest plugin to check FLAKE8 requirements
Project description
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 that if optional flake8 plugins are installed, those will also be used.
Configuring FLAKE8 options per project and file
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 ======================================= test session starts ======================================== platform darwin -- Python 2.7.6 -- py-1.4.26 -- pytest-2.7.0 -- /Users/tholo/Source/pytest/bin/python cachedir: /Users/tholo/Source/pytest/src/verify/.cache rootdir: /Users/tholo/Source/angular/src/verify, inifile: setup.cfg plugins: flake8, cache collected 1 items myfile.py PASSED ========================================= 1 passed in 0.00 seconds =========================================
Note that doc/conf.py was not considered or imported.
