Look at my original response to you. Your unit tests don't need to test 
that Tk is doing its job (hopefully the Tk people are doing that, but 
seconding that, maybe your functional end-to-end tests are). Your unit 
tests only need to test that you are making the right calls to the right 
Tk methods.
