Neither can I -- which is precisely why I never write my classes
before my tests. Writing a class is _not_ design; that's called
"programming by intention". Figuring out what you need a class to do,
and then specifying the API is design. This is (part of) what the
tests do. They give you a chance to work with the interface as a
_client_ of that interface to see how things fit together _before_ you
commit yourself to the implimentaiton.
