Hello, I'm happy to announce the first release of a small QuickCheck implementation for OCaml, named `QCheck`. It consists in writing invariants as function t -> bool for some type t, and then checking that the invariant holds on randomly generated instances of t. QCheck is designed so that writing tests is as easy as possible[1], especially for Arbitrary instances (the part where you generate random values of a type) where it provides many combinators. The library requires OCaml >= 4.00.1, and is available under the BSD license on opam via: $ opam install qcheck You can find documentation at: http://cedeela.fr/~simon/software/qcheck/QCheck.html source code at: https://github.com/c-cube/qcheck and some explanations here: http://cedeela.fr/quickcheck-for-ocaml.html Feedback or comments welcome! Cheers, -- Simon [1] your mileage might vary ;)
