quickspec: Equational laws for free

[ bsd3, library, testing ] [ Propose Tags ]

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:

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.
