Using sinon.js to fake calls to multiple URLs in a test

sinon.js

var server = sinon.fakeServer.create();
  	var result1;
		var result2;

		server.respondWith("url/one", '{ "id": 1 }');
		server.respondWith("url/two", '{ "id": 2 }');

		$.getJSON('url/one', function(data) {
  		result1 = data;
		});

		$.getJSON('url/two', function(data) {
  		result2 = data;
		});

		server.respond();

		expect(result1.id).toEqual(1);
		expect(result2.id).toEqual(2);

		server.restore();
