I found the test-framework package to be quite useful for this.

Using the defaultMain function you can easily define a small program
which will run all your tests (quickcheck, hunit or other). The only
problem I had with test-framework is that it prints the test results
in nice colours. It looks pretty in a console but unreadable in ghci.

Hackage seems to be down at the moment, but you can check out which
other packages use test-framework on my hackage plaything:
