monoidSpec :: (Show a, Eq a, Monoid a, Typeable a, GenValid a) => Specgenvalidity-hspec Test.Validity Standard test spec for properties of Monoid instances for valid values Example usage:
monoidSpec @[Int]
monoidSpecOnArbitrary :: (Show a, Eq a, Monoid a, Typeable a, Arbitrary a) => Specgenvalidity-hspec Test.Validity Standard test spec for properties of Monoid instances for arbitrary values Example usage:
monoidSpecOnArbitrary @[Int]
monoidSpecOnGen :: (Show a, Eq a, Monoid a, Typeable a) => Gen a -> String -> (a -> [a]) -> Specgenvalidity-hspec Test.Validity Standard test spec for properties of Monoid instances for values generated by a given generator (and name for that generator). Example usage:
monoidSpecOnGen (pure "a") "singleton list of 'a'"
