+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.
