At work we’ve been using selenium webdriver to enable automated browser testing as part of our regression suite. One of the most difficult parts we’ve had is maintaining DOM synchronization.

We use selenium extensively at work for automated acceptance tests. If you’ve never used selenium, it allows you to record and playback browser sessions and create integration tests from the perspective of a browser. Its generally a great tool, and really helps make sure we don’t release broken code. Recently, however I’ve found Selenium can have adverse reactions with jQuery.
