FYI: http://bit.ly/9UmUis The part that is interesting: "Improved JavaScript support, now all jQuery and Mochikit tests pass, adding to already supported GWT and Sarissa" Since we're moving to Selenium2 and Selenium2 has a driver for HtmlUnit, we should try and see if using it would be good enough to detect JS problems in various browsers. The advantage of it over real browser drivers is that it runs much faster. Or we could imagine a scenario where we would use the HtmlUnit driver for standard functional tests and then use the real browser driver once per day to provide additional warranties, thus providing the best of both worlds. -Vincent
