Test cases as far as? Can you give your use case further?
When I test my processes I just feed in data and check the outputs for proper output.
You can write driver processes if you want or if you wanted to automated some testing you could do tables of inputs and pass the inputs in.
I could give a better answer if you let me know what you are trying to accomplish.
thanks!
