[issue35767] unittest loader doesn't work with partial test functions

[Jason Fried]

New submission from Jason Fried <me at jasonfried.info>:

https://github.com/python/cpython/blob/3.7/Lib/unittest/loader.py#L232

fullName = '%s.%s' % (testCaseClass.__module__, testFunc.__qualname__)

Instead we should probably replace testFunc.__qualname__ with attrname

I ran into this while running a test suite that built up test functions using partials and added them to the TestCase class with setattr. 

This works in 3.6.3
