title: How to assert a dict contains another dict without assertDictContainsSubset in python?
body: <p>I know <code>assertDictContainsSubset</code> can do this in python 2.7, but for some reason it's deprecated in python 3.2. So is there any way to assert a dict contains another one without <code>assertDictContainsSubset</code>?</p>
  
  <p>This seems not good:</p>
  
  <pre><code>for item in dic2:
      self.assertIn(item, dic)
  </code></pre>
  
  <p>any other good way? Thanks</p>
