pytest pylint

Run pylint with pytest and have configurable rule types (i.e. Convention, Warn, and Error) fail the build. You can also specify a pylintrc file.

Sample Usage

py.test --pylint

would be the most simple usage and would run pylint for all error messages.

py.test --pylint --pylint-rcfile=/my/pyrc --pylint-error-types=EF --pylint-jobs=4

This would use the pylintrc file at /my/pyrc, only error on pylint Errors and Failures, and use 4 cores for running pylint.

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

py.test --pylint -m pylint
