test-invariant: Provide common invariants to be checked with QuickCheck

[ bsd3, library, testing ] [ Propose Tags ]

test-invariant is a library for providing common invariants of functions as higher order polymorphic functions. This reduces for a lot of cases the need for writing prop_ functions for QuickCheck.

>>> quickCheck $ idempotent (abs :: Int -> Int)
>>> quickCheck $ involutory not
>>> quickCheck $ not . involutory (+ (2 :: Int))
