This plugin produces coverage reports. Compared to just using coverage run this
plugin does some extras:
• Subprocess support: you can fork or run stuff in a subprocess and will get
covered without any fuss.
• Xdist support: you can use all of pytest-xdist’s features and still get
coverage.
• Consistent pytest behavior. If you run coverage run -m pytest you will have
slightly different sys.path (CWD will be in it, unlike when running
pytest).
All features offered by the coverage package should work, either through
pytest-cov’s command line options or through coverage’s config file.
