title: Test Method returning error "Assertion after the final `assert.async` was resolved"
body: <p>I am trying to test javascript method as below,</p>
  
  <pre><code>var spyPostRender = sinon.spy(proxy, "postRender");
  var done = assert.async();
  proxy.init();
  done();
  assert.ok(spyPostRender.calledOnce, "postRender() function was called.");
  </code></pre>
  
  <p>where init() internally calls an ajax service, however when I do this, I am getting below error. Can anybody help me in resolving this issue?</p>
