[Haskell-cafe] combining HUnit and QuickCheck

[Lemming]

I want to run randomized tests and others and I thought it would be a 
good idea to run QuickCheck tests in the HUnit framework. Eventually if 
a test fails the program shall fail. I couldn't figure out how to obtain 
the test result and a meaningful diagnostic message from QuickCheck. The 
functions I've found (quickCheck, test, runTests) report everything to 
the standard output. There is also QuickCheck.Batch.run which returns a 
TestResult. I wonder if there is already a function which decides 
whether the TestResult is a success or not and a function which turns 
the TestResult into a error string.
