[New-bugs-announce] [issue35047] Better error messages un unittest.mock

[Petter S]

New submission from Petter S <petter.strandmark at gmail.com>:

When developing unit tests with `unittest.mock`, it is common to see error messages like this:

    AssertionError: Expected 'info' to not have been called. Called 3 times.

It would be really helpful if those 3 calls were listed in the assertion error.

I am happy to add this if people agree it is a good thing.
