I've performed the "Replace Method with Method Object" refactoring described by Beck.

Now, I have a class with a "run()" method and a bunch of member functions that decompose the computation into smaller units. How do I test those member functions?

My first idea is that my unit tests be basically copies of the "run()" method (with different initializations), but with assertions between each call to the member functions to check the state of the computation.

(I'm using Python and the unittest module.)
