Sinon synchronous tests with Q promises

Q-promises-synch-tests.md

The code below will effectively turn your Asynchronous Q promises synchronous so that they are easier to test.

  beforeEach(function () {
    sinon.stub(Q.xhr, 'post').returns(Q.resolve({myAwesome: 'response data goes here'}));
    sinon.stub(process, 'nextTick').yields();
  });

  afterEach(function () {
    Q.xhr.post.restore();
    process.nextTick.restore();
  });
