The following class + helper functions implement law-agnostic testing functionality that is used to test laws for various classes.

- class TestEqual b where
- testRunEq :: Show r => (t -> p -> r) -> (r -> r -> Bool) -> Equal t -> p -> Property
- testEq :: Show a => (a -> a -> Bool) -> Equal a -> Property
- testRunEqPartial :: Show (Partial r) => (t -> p -> r) -> (r -> r -> Bool) -> Equal t -> p -> Property
- testEqPartial :: Show (Partial a) => (a -> a -> Bool) -> Equal a -> Property
- pairwiseEq :: (r -> r -> Bool) -> [r] -> Bool
- type Pos = Int
- failingPair :: (a -> a -> Bool) -> Equal a -> (Pos, a, a)
- failingPair' :: Num t => t -> (t1 -> t1 -> Bool) -> [t1] -> (t, t1, t1)

testEq :: Show a => (a -> a -> Bool) -> Equal a -> PropertySource

The second function, `testEq`

, does the same, but now for pairs
that are not necessarily runnable.

testRunEqPartial :: Show (Partial r) => (t -> p -> r) -> (r -> r -> Bool) -> Equal t -> p -> PropertySource

pairwiseEq :: (r -> r -> Bool) -> [r] -> BoolSource
