title: Are IE7/IE8 browser/document modes in IE9 equivalent to the real browsers?
body: <p>Our QA team needs to test our website in IE9, IE8, and IE7.</p>
  
  <p>Rather than have separate machines for each IE version, could testers simply run IE9 in IE8 or IE7 mode?</p>
  
  <p>For example, could a QA tester simply set the following and have and identical "IE8" experience:</p>
  
  <ul>
  <li><p>Browser Mode: IE8</p></li>
  <li><p>Document Mode: IE8 Standards</p></li>
  </ul>
  
  <p>Has Microsoft made any specific recommendations on this?</p>
  
  <p>(Our fallback option is to run VPC compatibility images, but that requires more effort to set up on testers' machines.)</p>
