[issue10675] unittest should have an assertChanges context manager

[R. David Murray]

R. David Murray <rdmurray at bitdance.com> added the comment:

I think this is the kind of thing where you are *much* better off writing a specialized assert method that exactly fits your use case.  There are too many variations on this theme, IMO, for it to make sense as an stdlib method.
