Is there a way to opt out of PytestReturnNotNoneWarning ?

As of pytest 7.2.0 , any test function that returns something not a None now gets a PytestReturnNotNoneWarning. Looking at its memo in https://github.com/pytest-dev/pytest/blob/main/doc/en/deprecations.rst , I do not see a way to tell pytest, “It’s okay, this return is intentional, just let it return stuff and not emit the warning.”

How do I opt out of this warning?

What’s the problem this feature will solve?

This will let me keep using https://github.com/matplotlib/pytest-mpl plugin because it requires returning the Matplotlib figure object for image comparison.

Describe the solution you’d like

Let me opt out.

Tell https://github.com/matplotlib/pytest-mpl devs how to rework their plugin to not return stuff.

Okay. I also asked at https://github.com/matplotlib/pytest-mpl/issues/183 🤞

Nope it won’t, that’s why I said “pytest-mpl probably needs to be updated”.
