What's the recommended way to unittest Python GUI applications?

Question

I\'m currently foolish enough to try to maintaintain two parallel code bases for a Python desktop application, one using PyGObject introspection for GTK 3 and one using PyGTK fo

Are you sure you want to unit test the GUI? Your example of complexity involves more than 1 unit and is therefore an integration test.

If you really want to unit test, you should be able to instantiate a single class providing mocks or stubs for its dependencies, then call methods on it like the GUI framework would for e.g. a user click. This can be tedious and you have to know exactly how the GUI framework dispatches user input to your classes.

My advice is to put even more stuff in models. For your given example you could create a FilterManager which abstracts all the filter/select/display stuff behind a single method. Then unit test it.
