forAll package:tasty-quickcheck

Explicit universal quantification: uses an explicitly given test case generator.
Like forAll, but without printing the generated value.
Like forAll, but with an explicitly given show function.
Like forAll, but tries to shrink the argument for failing test cases.
Like forAllShrink, but without printing the generated value.
Like forAllShrink, but with an explicitly given show function.
Optional; used internally in order to improve shrinking. Tests a property but also quantifies over an extra value (with a custom shrink and show function). The Testable instance for functions defines propertyForAllShrinkShow in a way that improves shrinking.
