Hmm, mysterious. I wonder if this comment will fix it for you: https://github.com/matplotlib/pytest-mpl/issues/69#issuecomment-492311398.

If you can, clone the git repository, open the setup.cfg file in the astroplan top-level directory and add the lines:

markers =
    mpl_image_compare

under the header [tool:pytest]. Then run python setup.py test and see if the tests pass.

I think this was fixed. Please reopen if necessary!
