quickcheck-dynamic

A library for testing stateful programs using QuickCheck and dynamic logic.

Background

This library was initially designed by QuviQ in collaboration with IOG to provide a dedicated test framework for Plutus "Smart contracts". As the need of a Model-Based Testing framework arises in quite a lot of contexts, it was deemed useful to extract the most generic part as a standalone package with no strings attached to Plutus or Cardano.

Usage

Documentation is currenly mostly provided inline as Haddock comments. Checkout StateModel and DynamicLogic modules for some usage instructions.
For a concrete standalone example, have a look at the Registry and RegistryModel module from the test suite, which respectively implement and model a multithreaded Thread registry inspired by the Erlang version of QuickCheck described in this article
For more documentation on how to quickcheck-dynamic is used to test Plutus DApps, check this tutorial.
Apart from Plutus, this library is now in use in the Hydra project to verify the Head Protocol implementation with respect to the original research paper.
