test_results_order: function () {
    var stack = new Y.Parallel(),
        test = this;

    setTimeout(stack.add(function () {
        return 1;

    stack.done(function (results) {
        test.resume(function() {
            Y.ArrayAssert.itemsAreEqual(results, [1, 2, 3], 'Results array did not retain order of callbacks');
        });
    });
