Error running pytest

When running pytest I am greeted by this error:

(mnedev) ✘-TSTP /mnt/d/git/obergmartin/mne-python [main|⚑ 1] 
11:33 $ pytest mne/tests/test_evoked.py -k test_io_evoked --verbose
ERROR: usage: pytest [options] [file_or_dir] [file_or_dir] [...]
pytest: error: unrecognized arguments: --cov-branch --cov-report=
  inifile: /mnt/d/git/obergmartin/mne-python/pyproject.toml
  rootdir: /mnt/d/git/obergmartin/mne-python

I set up mne with a conda environment, but the same error occurs with my usual python venv installation.

I am using WSL2 on Win11.

You need pytest-cov (and possibly some other packages), I recommend uv sync to install the most important dependencies.

Thanks!
I see now that I missed: pip install --group=test
