title: Mocha 'before each hook' message in red. How do I know what specifically is wrong?
body: <p>I have the following message, just before a failing test:</p>
  
  <pre><code>1) "before each" hook 
  </code></pre>
  
  <p><strong>That is the the entire message</strong>. It is in red, which makes me think there is something wrong with the before each hook, but I'm unsure of what the error is. It could be:</p>
  
  <ul>
  <li>A failed timeout</li>
  <li>A failed assertion</li>
  <li>An Error being thrown</li>
  </ul>
  
  <p>How do I know what the error is? </p>
  
  <p>This particular <code>beforeEach()</code> normally executes perfectly fine. </p>
