[issue27341] mock.patch decorator fails silently on generators

[Shoshana Berleant]

New submission from Shoshana Berleant:

(at least in my case)

I committed two tests before I realized the tests were not being run: https://github.com/nipy/nipype/blob/abe7920a051f1570ccce4b71f26f50102d6e4e12/nipype/testing/tests/test_utils.py#L23

I realized this afternoon, while writing some more tests, that tests with the patch decorator were all reported as "OK", even when I wanted them to fail. Turns out they aren't being run at all.

I commented out all the yield statements, and the tests ran just as they should.

I don't know exactly what is going on here, but might raising an error or warning be good here?
