Victor proposed in issue25994 to use special context manager to check that no ResourceWarning is emitted. I think that this helper can be useful in other tests. It saves 3 lines for every use. Proposed patch adds it in

Oh, I didn't expect that so many existing test already use the same pattern to check for ResourceWarning. Nice patch!

I added a comment: we must be careful in the documentation of the helper.

I was about to suggest adding this to as well. Patch looks good to me.

Addressed Victor's comments.

This pattern is not widely used. Usually only raising ResourceWarning is tested, but not non-raising.
