SmallCheck is similar to QuickCheck (Claessen and Hughes 2000-) but
 instead of testing for a sample of randomly generated values, SmallCheck
 tests properties for all the finitely many values up to some depth,
 progressively increasing the depth used.

 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
