[[Category:Packages]] == Abstract == '''checkers''' is a library for reusable QuickCheck properties, particularly for standard type classes (class laws and [http://conal.net/papers/simply-reactive class morphisms]). For instance, a good deal of [[Reactive]] can be specified and tested using just these properties. Checkers also lots of support for randomly generating data values (thanks to Thomas Davie).
