This doesn't quite answer your question but...

I strongly recommend looking at quickcheck

  http://www.cs.chalmers.se/~rjmh/QuickCheck/

which provides a lot of help in building good test-suites.

If you want conditional compilation, you might also check out
 the -F <filter-program> feature in Hugs which lets you specify
 a preprocessor (such as cpp or perl) to use with your Haskell code.
