title: Where is my test helper for ember-power-select?
body: <p>I am reading the docs for <code>ember-power-select</code> testings <a href="http://www.ember-power-select.com/docs/test-helpers" rel="nofollow noreferrer">here</a>.</p>
  
  <p>On the setup, it says:</p>
  
  <pre><code>import registerPowerSelectHelpers from '../../tests/helpers/ember-power-select';
  
  registerPowerSelectHelpers();
  ...
  </code></pre>
  
  <p>I do not see <code>ember-power-select</code> in my <code>tests/helpers/</code> directory. Am I supposed to install it separately, or was it supposed to come by default?</p>
  
  <p>I installed <code>ember-power-select</code> by running the command suggested: <code>ember install ember-power-select</code>. </p>
  
  <p>How can I use some of the <code>power-select helpers</code> like <code>selectChoose()</code>, <code>selectSearch()</code>, &amp;c. like prescribed on the docs?</p>
