I don't know exactly what your problem is, but perhaps you have not
specified Cabal-Version: >= 1.2?
For another example .cabal file that uses something like the technique
Sean describes you can look at my edit-distance library on GitHub:
It exports a library with the edit distance algorithms and a test
executable which is only buildable when configured with -ftests. I
haven't made use of the Cabal test hook, but you can run the tests
just by running that single executable: the procedure is described in
my README: http://github.com/batterseapower/edit-distance/tree/master/README.textile
My tests are making use of a nice console test runner I wrote that
supports both HUnit and QuickCheck (and is extensible to other test
providers by the user):
