Pycharm/IntelliJ shows 0% coverage for pytest even though coverage was generated

I have a Python project and a

tests

task, set up to run

pytest

from the project's working directory.

Doing

Run 'tests' with coverage

from the

Run

menu successfully runs the tests, and the console results shows that coverage was measured - e.g. 53% cover for

mws.py

The automatically applied coverage (as on the right) is 0% for all files, I'm not sure why. I'm using IntelliJ 2017.2.2 EAP.

NB: there is a related five year old question here, but the top rated solution there doesn't apply. There is no error message in the results console in this case.

I think the problem lies in you use pytest-cov, so Pycharm cannot parse the result which is shown in text like 53% generated by pytest-cov;

So Changes option in pytest.ini to addopts = -s -v when you want to use Pycharm built in coverage tools.
