For python 3.6 (debian 18.04) mock is 

  /usr/lib/python3/dist-packages/mock/mock.py

and starts:

   # mock 1.0.1
   # http://www.voidspace.org.uk/python/mock/
   #
   # Copyright (c) 2007-2013, Michael Foord & the mock team

and diffing it against /usr/lib/python3.6/unittest/mock.py which starts:

   # mock.py
   # Test tools for mocking and patching.
   # Maintained by Michael Foord
   # Backport for other versions of Python available from
   # https://pypi.org/project/mock

makes it look like unittest/mock.py is just a different version of
mock/mock.py.

However there is no mock in unittest under my python2.7.

I have changed that import to read:

try:
   from unittest.mock import Mock
except ImportError:
   # python 2.7
   from mock import Mock

and successfully run that test module under python2.7 and 3.6.
