  NIH (not invented here) is a syndrome from which I suffer. Luckily, I'm pretty good about not 

  suffering from it when somebody else is paying me to do something in a timely manner. But if 

  I'm working on my own personal project, you can bet I will be inventing a universe before 

  releasing something.

<p>

  And out popped <a href="https://jarvis.tmont.com/">Jarvis</a>. Another unit testing framework 

  for JavaScript.

</p>

<p><code>YAWN.</code></p>

<p>Anyway, I wrote my own because:</p>

<ol>

  <li>It's fun (seriously)</li>

  <li>

      I've done it before in <a href="https://github.com/tmont/testify">PHP</a> and 

      <a href="https://github.com/tmont/ntestify">C&#x266f;</a>

  </li>

  <li>I didn't really like the other ones available (disclaimer: I didn't actually look at any of the other ones available)</li>

</ol>

<p>Clearly, it was a good decision.</p>

<h3>Features</h3>

<ul>

  <li>Assertions (ooh!)</li>

  <li>Assertions on the DOM using jQuery (i.e. Sizzle) selectors</li>

  <li>Stack traces!</li>

  <li>Displays fancy diffs for string comparisons!</li>

  <li><a href="https://jarvis.tmont.com/test/">Uses itself to test itself!</a></li>

  <li>Gradients! Drop shadows! CSS3! Web 2.0!</li>

  <li>Exclamation points!</li>

</ul>

<p>Here's a gratuitous screenshot:</p>
