Hi @danielhollas, did you also have the following warning after you turn waring to error in pytest?

        # The call to .warn adds one frame, so bump the stacklevel up by one
>       warnings.warn(message, DeprecationWarning, stacklevel=stacklevel + 1)
E       DeprecationWarning: Jupyter is migrating its paths to use standard platformdirs
E       given by the platformdirs library.  To remove this warning and
E       see the appropriate new directories, set the environment variable
E       `JUPYTER_PLATFORM_DIRS=1` and then run `jupyter --paths`.
E       The use of platformdirs will be the default in `jupyter_core` v6

Possibly, I've definitely seen it before. I think take a look at pyproject.toml at AWB and copy the ignore lines from there.
