[New-bugs-announce] [issue39766] unittest's assertRaises removes locals from tracebacks

[daniel hahler]

New submission from daniel hahler <python-bugs at thequod.de>:

I was a bit surprised to find that unittest's assertRaises clears the locals on the traceback, which e.g. prevents pytest to display them in case of failures.

This was done via https://bugs.python.org/issue9815 (https://github.com/python/cpython/commit/9681022f1ee5c6c9160c515b24d2a3d1efe8b90d).

Maybe this should only get done for expected failures, so that unexpected exceptions can be inspected better?
