Description
Ord properties
You will need TypeApplications to use these.
Synopsis
- ordSpec :: (Show a, Ord a, Typeable a, GenValid a) => Spec
- ordSpecOnGen :: (Show a, Ord a, Typeable a) => Gen a -> String -> (a -> [a]) -> Spec
- ordSpecOnArbitrary :: (Show a, Ord a, Typeable a, Arbitrary a) => Spec
Documentation
ordSpec :: (Show a, Ord a, Typeable a, GenValid a) => Spec Source #
Standard test spec for properties of Ord instances for valid values
Example usage:
ordSpec @Int
ordSpecOnGen :: (Show a, Ord a, Typeable a) => Gen a -> String -> (a -> [a]) -> Spec Source #
Standard test spec for properties of Ord instances for values generated by a given generator (and name for that generator).
Example usage:
ordSpecOnGen ((* 2) <$> genValid @Int) "even"
ordSpecOnArbitrary :: (Show a, Ord a, Typeable a, Arbitrary a) => Spec Source #
Standard test spec for properties of Ord instances for arbitrary values
Example usage:
ordSpecOnArbitrary @Int
