How to properly unit test jQuery's .ajax() promises using Jasmine and/or Sinon?

Question

I\'ve got a fairly straightforward function which returns a jQuery .ajax() promise as such:

CLAW.controls.validateLocation = function(val, $inputEl) {
    re

Here's a simpler approach with just javascript.

quoteSnapshots: function (symbol, streamId) {
                var FakeDeferred = function () {
                    this.error = function (fn) {
                        if (symbol.toLowerCase() === 'bad-symbol') {
                            fn({Error: 'test'});
                        }
                        return this;
                    };
                    this.data = function (fn) {
                        if (symbol.toLowerCase() !== 'bad-symbol') {
                            fn({});
                        }
                        return this;
                    };
                };

                return new FakeDeferred();
            }

The if statements inside of each callback are what I use in my test to drive a success or error execution.
