False error: pylint + pytest 6 - pytest.mark.parametrize is not callable (not-callable)

[adamtheturtle]

Steps to reproduce

Use pytest.mark.parametrize, e.g.

"""
Example pytest mark.
"""

import pytest

@pytest.mark.parametrize('sample', [0])
def test_example(sample):
    """
    Example test.
    """
    assert sample == 0

Install pytest==6.0.0.
Run pylint.

Current behavior

• The test passes when running pytest.

I see the error:

test_example.py:7:1: E1102: pytest.mark.parametrize is not callable (not-callable)

This error is not shown with pytest==5.4.3.

Expected behavior

No error is shown.

If it helps any, I am seeing the same errors with pytest.mark.skip, pytest.mark.skipif, and pytest.mark.xfail on version:
pylint 2.5.3 astroid 2.4.2 Python 3.7.4 (default, Aug 14 2019, 12:19:22) [GCC 8.3.0]
and pytest 6.0.0

It seems that the pytest folks are handling this particular case - pytest-dev/pytest#7565.

[adamtheturtle]

pytest has now released a change which avoids this error. I guess either this issue should be closed, or it should be investigated why pylint showed an error on Python code which worked.

Thanks for the report. Since this is fixed on pytest side, let's close this. We can definitely investigate why this was the case, but with 600+ opened issues, I doubt it's that important.
