title: Selenium vs Celerity?
body: <p>Isn't Selenium better than Celerity when it comes to testing web sites cause real browsers like Firefox, Safari, Chrome and Internet Explorer could be used so that we know our website is compatible with each of them.</p>
  
  <p>So if I use Celerity (it's java browser), even if all tests pass, doesn't that mean my website could still be incompatible with our popular web browsers?</p>
  
  <p>I know it's slower, but if we do not take that into account, isn't Celerity more error prone then?</p>
