title: Mouse movement / mouseover and JavaScript evaluation in watir
body: <p>I have a JavaScript-heavy Rails app which I am testing in watir. I have two specific testing requirements:</p>
  
  <ul>
  <li>I need to be able to simulate moving the mouse to a specific area of the screen (or at least triggering the onmouseover event for a div)</li>
  <li>Evaluating a snippet of JavaScript once the above has happened to see if a flag is set correctly</li>
  </ul>
  
  <p>I haven't been able to figure out how to do this in watir. Any ideas on how to do this?</p>
