title: how do i unit test an Ember Router?
body: <p>i've looked at the unit testing for Ember.Router and noticed that it does not define any connectOutlets() on its routes.</p>
  
  <p>however, i want to understand how i should unit test my own extension of the Router in my app.  obviously i don't want all the dom elements instantiating for a unit test.  is there a way to unit test the Router in isolation?  some sort of 'headless' or 'testing' flag?</p>
  
  <p>or should i just concentrate on integration testing and put my router tests in there?</p>
  
  <pre><code> App.Router = Ember.Router.extend({})
  </code></pre>
