Testing RSVP.Promises

No, Chai as Promised does not try to make promises fake-synchronous. If you want to expand the featureset of Sinon.JS to support different methods of fake-sync, feel free to file a bug there. It is not in scope for Chai as Promised.

If you don't try to hide the asynchronicity in your tests, you can either test using the notify helper:

chai.expect(this.promise).to.be.fulfilled.notify(done);

or using Mocha as Promised.

Righto! This is behaving as expected http://jsfiddle.net/TqA5R/11/

    it("EXPECTED TO FAIL! should not be fulfilled on reject", function(done) {
        this.promise.reject();
        chai.expect(this.promise).to.be.fulfilled.notify(done);
    });
    it("should be fulfilled on resolve", function(done) {
        this.promise.resolve();
        chai.expect(this.promise).to.be.fulfilled.notify(done);
    });

The expected to fail fails. Thanks for the tip @domenic !

Glad to help! BTW I'm pretty sure the "done invoked with non-Error" is JSFiddle specific, since they use iframes and so instanceof Error fails cross-frame.
