The quickspec package
QuickSpec automatically finds equational properties of your program.
Give it an API, i.e. a collection of functions, and it will spit out equations about those functions. For example, given reverse, ++ and , QuickSpec finds six laws:
xs++ == xs ++xs == xs reverse  ==  (xs++ys)++zs == xs++(ys++zs) reverse (reverse xs) == xs reverse xs++reverse ys == reverse (ys++xs)
All you have to provide is:
Some functions and constants to test. These are the only functions that will appear in the equations.
A collection of variables that can appear in the equations (xs, ys and zs in the example above).
Test.QuickCheck.Arbitrary and Data.Typeable.Typeable instances for the types you want to test.
Consider this a pre-release. Everything is complete but undocumented :) The best place to start is the examples at http://github.com/nick8325/quickspec/tree/master/examples. There is also a paper at http://www.cse.chalmers.se/~nicsma/quickspec.pdf. Everything you need should be in the module Test.QuickSpec.
