monoidSpec :: forall a. (Show a, Eq a, Monoid a, Typeable a, GenUnchecked a) => Spec

Standard test spec for properties of Monoid instances for unchecked values

Example usage:

monoidSpec @[Int]

monoidSpecOnArbitrary :: forall a. (Show a, Eq a, Monoid a, Typeable a, Arbitrary a) => Spec

Standard test spec for properties of Monoid instances for arbitrary values

Example usage:

monoidSpecOnArbitrary @[Int]

monoidSpecOnGen :: forall a. (Show a, Eq a, Monoid a, Typeable a) => Gen a -> String -> (a -> [a]) -> Spec

Standard test spec for properties of Monoid instances for values generated by a given generator (and name for that generator).

Example usage:
