The change itself looks good to me, but the remaining assert statements in the test case need to be converted to the appropriate unittest methods: https://docs.python.org/3/library/unittest.html#assert-methods
Lib/test/test_raise.py
Outdated

These assertions all need to use the unittest assert methods, not assert statements.

This mostly looks good to me now, just a minor comment relating to the possible use of assertIsInstance for slightly nicer failure messages.
Marking my review as approved anyway though, as I'll be offline until tomorrow, and I'm fine with someone else merging this in the meantime :)

There's a dedicated method for this one that gives a nicer message when it fails: https://docs.python.org/3/library/unittest.html#unittest.TestCase.assertIsInstance
This is admittedly an obscure use case, but currently there are projects like Jinja2 and Trio that are forced to work around this with horrible ctypes hacks: https://github.com/pallets/jinja/blob/fe3dadacdf4cf411d0a5b6bbd4d5234697a28af2/jinja2/debug.py#L345 https://github.com/python-trio/trio/blob/1e86b1aee8c0c759f6f239ae53a05d0d3963c629/trio/_core/_multierror.py#L296
