QuickCheck is a library for random testing of program properties.

The programmer provides a specification of the program, in the form of properties which functions should satisfy, and QuickCheck then tests that the properties hold in a large number of randomly generated cases.

Specifications are expressed in Haskell, using combinators defined in the QuickCheck library. QuickCheck provides combinators to define properties, observe the distribution of test data, and define test data generators.

[Skip to Readme]





Choose the new smaller, split-up base package.


Choose the even newer base package with extensible exceptions.


Build Test.QuickCheck.All, which uses Template Haskell.


Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info


Note: This package has metadata revisions in the cabal description newer than included in the tarball. To unpack the package including the revisions, use 'cabal get'.

Readme for QuickCheck-2.7.3

[back to package description]
This is QuickCheck 2, a library for random testing of program properties.

Install it in the usual way:

$ cabal install

Please report bugs to the QuickCheck mailing list at

If you get errors about Template Haskell, try

$ cabal install -f-templateHaskell

but please report this as a bug.
