The quickspec package
QuickSpec automatically finds equational laws about 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, which are exactly the ones you might write by hand:
xs++ == xs ++xs == xs (xs++ys)++zs == xs++(ys++zs) reverse  ==  reverse (reverse xs) == xs reverse xs++reverse ys == reverse (ys++xs)
The laws that QuickSpec generates are not proved correct, but have passed at least 200 QuickCheck tests.
