Using py.test with coverage doesn’t include imports
@hynekcer gave me the right idea. But basically the easiest solution lies somewhere else: Get rid of pytest-cov! Use coverage run –source jedi -m py.test coverage report instead!!!

How to properly use coverage.py in Python?
Coverage looks for a .coverage file to read and generate that report for you. Py.test on its own does not create one.
