The inconclusive assert would be used as follows:

test("My test", function () {
          inconclusive();
          // or with message        
         inconclusive("The submit click handler needs a test case");
});

When run the, the test would display in (say) orange (compared to red for fail and green for pass) , with the provided message or the default "Test pending" message.

We've hacked this together to work for us, here is a snippet that adds a class for the styling.

li.className = assertion.result === null ? "inconclusive" : (assertion.result ? "pass" : "fail");

It would be great if this can be included in the API.

It has proven very useful for creating place-holders for pending tests, and also for frameworks on top of QUnit that iterate an object and flag untested methods.

Thanks.
