@Paul: Sure, here it is. I hope it’s useful to you.

  function quickcheck (args, test, config)

  {

    if (!config) config = new Config(100, 1000);

    var p = new Prop("", args, test);

    var res = runProp(config, p);

    var passed = res.status === "pass";

    var msg = res.status

    if (res.status === "fail") msg += " on " + QUnit.jsDump.parse(res.failedCase);

    msg += " (" + res.counts.pass + " passed, " + res.counts.invalid + " invalid)";

    ok(passed, msg);

  }

Thanks
