I have a python program that imports pythoncom (and uses pythoncom.CoCreateInstance from it). I want to create a unittest for the program logic without it importing pythoncom (so I can run the test on Linux as well).

What options are there? Can I do it without modifying the system under test?

What I found so far: sys.modules["pythoncom"] = "test" import module_that_imports_pythoncom

My problem with it is if I have: from pythoncom.something import something I'll get: ImportError: No module named something.something And sys.modules["something.something"] or sys.modules["pythoncom.something.something"] doesn't work.

Any ideas?
