No coverage report

I'm trying to test a flask app, and I'm not getting any coverage reporting information when using this plugin

$ pytest -W ignore::DeprecationWarning --func_cov=my_project tests/

Same issue for me. I tried with

foo/foo.py

def foo():
    return True

and

tests/test_foo.py

from foo import foo

def test_foo():
    assert foo() is True

and command

pytest --func_cov=foo --func_cov_report=term-missing tests

and could reproduce the issue:

=> Coverage for function 'foo' should be 100 %

=> Did anyone successfully use pytest_func_cov?
