we're not big on hyped, capitalized words, but many of us like tests. 
There's even a tool, "HPC" (Haskell Program Coverage) that you can use 
when you run your tests to see how much of the code is reached at all by 
the tests.

Actually, in terms of writing tests before writing code (which I 
sometimes do)... what Haskellers often do even more often is to write 
type-signature for functions before they write the function's code. 
This helps testing (i.e. test failure = compile-time type errors) as 
well as thinking about what you want the function to do.  Types are 
generally more useful-for-thinking in FP than in imperative languages

I would use QuickCheck first... have you taken a look at it?
