[Caml-list] [ANN] QCheck 0.1

[Caml-list] [ANN] QCheck 0.1

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,

Is it supported by qtest?

I.e. can some qtest tests in comments use this QCheck library?

Best regards,

I don't think so, but it would be great for people who like to write
tests near the code. I'm not familiar with qtest, so I'm not going to
implement it now (patchs welcome ^^), but it would definitely be
interesting to have the invariants close to the algorithms!
