title: Ember Testing: Why use Assert.?
body: <p>I see a lot of examples (including ember-cli generated tests) that use <code>assert.function()</code> but I can use the function as is, so am I doing something wrong, or do examples just show not-really-necessary qualifiers?</p>
  
  <p>For example, either of these work in a new generated unit test:</p>
  
  <p><code>assert.expect(1);</code></p>
  
  <p><code>expect(1);</code></p>
  
  <p>Why ever do the first one if the second one works?</p>
