I'm trying to test some jQuery ajax code using QUnit and Mockjax and have it return different JSON for different tests, like this:

$(document).ready(function() {

function functionToTest() {
    return $.getJSON('/echo/json/', {
        json: JSON.stringify({
            "won't": "run"
        })
    });
}

module("first");

test("first test", function() {

    stop();

    $.mockjax({
        url: '/echo/json/',
        responseText: JSON.stringify({
            hello: 'HEYO!'
        })
    });

    functionToTest().done(function(json) {
        ok(true, json.hello);
        start();
    });               
});


 test("second test", function() {

    stop();

    $.mockjax({
        url: '/echo/json/',
        responseText: JSON.stringify({
            hello: 'HELL NO!'
        })
    });


    functionToTest().done(function(json) {
        ok(true, json.hello);
        start();
    });


});

});

Unfortunately it returns the same response for each call, and order can't be guaranteed, so was wondering how I could set it up so that it was coupled to the actual request and came up with this:

$.mockjax({
    url: '/echo/json/',
    response: function(settings) {

        if (JSON.parse(settings.data.json).order === 1) {
            this.responseText = JSON.stringify({
                hello: 'HEYO!'
            });
        } else {
            this.responseText = JSON.stringify({
                hello: 'HELL NO!'
            });
        }
    }
});

This relies on parameters being sent to the server, but what about requests without parameters, where I still need to test different responses? Is there a way to use QUnit's setup/teardown to do this?
