• Randomized property-based testing plugin for Coq; a clone of Haskell QuickCheck
• Includes a foundational verification framework for testing code
• Includes a mechanism for automatically deriving generators for inductive relations

For more information on QuickChick, look at the tutorial available under the qc folder of the deep spec summer school: https://github.com/DeepSpec/dsss17

• Branch master:
  • Coq 8.8
  • OCaml >= 4.04.0
  • mathcomp-ssreflect-1.6.4
  • coq-ext-lib-0.9.7
  • coq-simple-io-0.2

# Add the Coq opam repository (if you haven't already)
opam repo add coq-released https://coq.inria.fr/opam/released
opam update
# Install the coq-quickchick opam package
opam install coq-quickchick

# To get the dependencies, you still need to add the Coq opam repository (if you haven't already)
opam repo add coq-released https://coq.inria.fr/opam/released
opam update
opam install coq-mathcomp-ssreflect coq-ext-lib coq-simple-io

# Then:
make && make install

• examples/Tutorial.v
• examples/RedBlack
• examples/stlc
• examples/ifc-basic

Running make tests in the top-level QuickChick folder will check and execute all of these. If successful, you should see "success" at the end.

The public API of QuickChick is summarized in BasicInterface.v.

The main documentation is the DeepSpec summer school tutorial:

• DeepSpec QC repo. Pretty soon this will become a software foundations volume!
