Description

Monoid properties

You will need `TypeApplications` to use these.

Synopsis

- monoidSpecOnValid :: forall a. (Show a, Eq a, Monoid a, Typeable a, GenValid a) => Spec
- monoidSpec :: forall a. (Show a, Eq a, Monoid a, Typeable a, GenUnchecked a) => Spec
- monoidSpecOnArbitrary :: forall a. (Show a, Eq a, Monoid a, Typeable a, Arbitrary a) => Spec
- monoidSpecOnGen :: forall a. (Show a, Eq a, Monoid a, Typeable a) => Gen a -> String -> (a -> [a]) -> Spec

# Documentation

monoidSpecOnValid :: forall a. (Show a, Eq a, Monoid a, Typeable a, GenValid a) => Spec Source #

Standard test spec for properties of `Monoid` instances for valid values

Example usage:

    monoidSpecOnValid @[Double]

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

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 Source #

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 Source #

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'"
