The checkers package

[Tags:bsd3, library]

'Checkers' wraps up the expected properties associated with various standard type classes as QuickCheck properties. Also some morphism properties. It also provides arbitrary instances and generator combinators for common data types.

Readme for checkers

Readme for checkers-0.1

Checkers [1] is a library for reusable QuickCheck properties, particularly
for standard type classes (class laws and class morphisms [2]).  Most of
Reactive [3] can be specified and tested using just these properties.
Also lots of support for randomly generating data values (thanks to Thomas
