+1 for Ezio's suggestion regarding tests that need the mock module. To simplify backporting you may want to do something like the following in a helper module:
 try:
 import unittest.mock as mock
 except ImportError:
 try:
 import mock
 except ImportError:
 mock = None
Then the individual test files would retrieve the mock attribute from the helper module and check it with the skip decorators in the tests that needed mocks.
