Cannot use Astroquery as a source with pytest-cov #3617
Description
This may be more of an upstream issue, but I can't use pytest-cov with an internal test suite we have running at MAST. Using coverage directly works, but I want to use pytest-xdist, which requires pytest-cov and doesn't work correctly with coverage.
I run the above test file with this command:
pytest --cov=astroquery.mast tests/test_minimal.py
The versions I have in my environment are:
- Python = 3.12
- pytest = 9.1.0
- pytest-cov = 7.1.0
- coverage = 7.14.1
- astroquery = 0.4.11 (or installed from GH)
- astropy = 7.2.0
- numpy = 1.26.4
The traceback I get is:
tests/test_minimal.py:1: in <module>

Two comments:
tox -e test-online-cov -- -P mastwithout any issues, so having issues with custom environments and pytest plugins that are not used in astroquery feels to be out of scope
