Test.QuickCheck.Poly

Types to help with testing polymorphic properties.

Types A, B and C are newtype wrappers around Integer that implement Eq, Show, Arbitrary and CoArbitrary. Types OrdA, OrdB and OrdC also implement Ord and Num.

See also Test.QuickCheck.All for an automatic way of testing polymorphic properties.
