pytest errors

[ejeschke]

Was seeing this warning while running tests recently:

$ pytest ginga/tests
...
=============================== warnings summary ===============================
/home/eric/miniconda3/envs/py37/lib/python3.7/site-packages/_pytest/config/__init__.py:1148
  /home/eric/miniconda3/envs/py37/lib/python3.7/site-packages/_pytest/config/__init__.py:1148: PytestConfigWarning: Unknown config ini key: astropy_header

    self._warn_or_fail_if_strict("Unknown config ini key: {}\n".format(key))

-- Docs: https://docs.pytest.org/en/stable/warnings.html
================== 170 passed, 14 skipped, 1 warning in 3.98s ==================

so I upgraded pytest from 6.0.1 to 6.2.4. With this new version, I get an enhanced traceback of the same error (complaining about unknown key for astropy_header):

Is this just something I need to clear out of a pytest cache or something?

Did you do a pip install -e .[test]?

No, that definitely fixed things. Thanks for the quick answer!

I think I had manually installed pytest-astropy-header previously and forgotten about it, because I had been running the tests for quite a while without problem. Upgrading the conda environment must have invalidated it.
