Test.Tasty.Hedgehog

This package lets you test Hedgehog properties with tasty.

Typical usage would look like this:

testGroup "tasty-hedgehog tests" [
   testProperty "reverse involutive" prop_reverse_involutive
 , testProperty "sort idempotent"    prop_sort_idempotent
 ]

Documentation

testProperty :: TestName -> Property -> TestTree
