I'm running the tests as I described here (PYTHONPATH="." pytest --pyargs pytest_trio), but it seems it doesn't recognize the marker correctly:

This is certainly not all locked down as I'm no Docker expert... but there's a Dockerfile and output below that seem to work.

Note: switching to '57f458dc59468b9cf88deb6c21791c1ee0a15673'.

You are in 'detached HEAD' state. You can look around, make experimental                                                                                             
changes and commit them, and you can discard any commits you make in this                                                                                            
state without impacting any branches by switching back to a branch.                                                                                                  

If you want to create a new branch to retain commits you create, you may                                                                                             
do so (now or later) by using -c with the switch command. Example:                                                                                                   

  git switch -c <new-branch-name>                                                                                                                                    

Or undo this operation with:                                                                                                                                         

  git switch -                                                                                                                                                       

Turn off this advice by setting config variable advice.detachedHead to false

Well this has nothing to do with Docker really, Alpine is used for more things 😉

I gave your command a shot and it failed, although differently:

ValueError: Plugin already registered: pytest_trio.plugin=<module 'pytest_trio.plugin' from '/home/bart/Documents/Git/alpine/aports/community/py3-pytest-trio/src/pytest-trio-0.6.0/pytest_trio/plugin.py'>

Strange that it works on the Dockerfile, I don't really do anything different...

Sorry for piling on with the ignorance there... and actually I recreated the same issue outside in my Ubuntu install.

Could you share the full command line and output anyways? Also include python -m pip freeze for the Python that the pytest is running from. And type python and head $(which pytest). Adjust all as needed so as to have them using the same Python. I'm looking to make sure pytest-trio isn't somehow installed now since the error sounds like it is and the PYTEST_PLUGINS is now redundant with the entry point plugin specification.

Or... maybe just seeing more stuff will help my light bulb turn on.
