This sounds like something that will be easier with nose (if I
understand nose correctly). Since the ufuncs are so uniform, it seems
like the zillion tests you are proposing writing should be expressed
as a list of ufuncs with some type annotations, a list of types to run
them against, and a programmatic expression of the type rules Robert
is proposing. While you can do this with the current test framework,
you get one test rather than many, and the failure report is not
nearly so valuable.
