I haven't even got to the use cases yet! This is still testing basic object interaction ("does Zobcrack auto-populate correctly when Fribnortz is instantiated?"). My worry is that I'll spend so long making sure the objects work that I'll run out of time on the project, or conversely will miss some object test that bites me later and proves difficult to track down.
I have a lot of semi-deterministic behaviour to model that is very sensitive to input conditions, and many object dependencies. *ponder* wouldn't it be great if there were some magic module that could take test harnesses and turn them into working code? Then all we'd have to do is write the test cases!
Any takers? :)
