QuickCheck

QuickCheck is a software library, specifically a combinator library, originally written in the programming language Haskell, designed to assist in software testing by generating test cases for test suites. It is compatible with the compiler, Glasgow Haskell Compiler (GHC) and the interpreter, Haskell User's Gofer System (Hugs). It is free and open-source software released under a BSD-style license.

In QuickCheck, assertions are written about logical properties that a function should fulfill. Then QuickCheck attempts to generate a test case that falsifies such assertions. Once such a test case is found, QuickCheck tries to reduce it to a minimal failing subset by removing or simplifying input data that are unneeded to make the test fail.

The project began in 1999. Besides being used to test regular programs, QuickCheck is also useful for building up a functional specification, for documenting what functions should be doing, and for testing compiler implementations.[1]

Re-implementations of QuickCheck exist for several languages:

• C[2][3][4]
• C++[5][6][7]
• Chicken[8]
• Clojure[9][10][11]

With Scheme-Check, instead of creating many individual tests, you specify properties of your code and Scheme-Check generates a large amount of random data sets to test those properties. Scheme-Check is basically a Scheme port of QuickCheck.
