title: Frameworks and tools for UI testing of ExtJS based web apps
body: <p>I would like to test a web app that was drastically redesigned to use ExtJS to drive its UI.</p>
  
  <p>I have done some online searching but couldn't find any recommendation for a good framework to handle it properly.</p>
  
  <p>Up till now we have been using WatiN to create tests.</p>
  
  <p>Note that we do not own the web app code.</p>
  
  <p>What are the best options currently available?</p>
