Example test case code here:

if True:
    from pycurl import Curl, version_info
else:
    from mock import Mock
    Curl = Mock()
    version_info = Mock()

Posting this in mypy, since I don't think it's possible to specify a typeshed type for mock.Mock that won't throw an error; e.g. if stubs say mock.Mock is an Any, you get /home/tabbott/foo.py:7: error: Invalid assignment target

Reporting as separate from #1152 since this might be worth solving even if that is not, since most every use of mock.Mock() will have this problem.
