I suggested an automated javascript testing framework for gsoc, was thinking watir rather than selenium based on a few discussions about both, but it didn't go anywhere:http://groups.drupal.org/node/9511, While I'd love to see testing with Selenium or Watir or some other browser remote control that can handle stuff that simpletest or straight up javascript unit testing can't, like cwgordon said, it's a matter of effort and returns. The testing framework we have in core has the advantage that anyone can download and run tests without needing to install other software, tests can be written in PHP, and we're getting close to the tipping point where our coverage is high enough to start finding regressions before they're committed. On the other hand, and unfortunately, at the moment we don't have that many jQuery intensive patches - yes, it's really annoying trying to get cross-browser tests when a new jQuery is released, but that's once every few months - so in terms of saving click around time SimpleTest is giving higher returns at the moment. While it might appear to be a lack of interest at the moment, it's more a case of 1. a lack of resources (the 'testing brigade' is still pretty small) 2. a need to get the testing framework we actually have up to a point where it begins to actually save some work - it'll only do this when we're closer to 100% test coverage and tests are being run on patches automatically via testing.drupal.org That said - it's very clear that the core testing framework can't cover everything, so extending it would be the natural next step - and given the amount of time and work it's taken to get to where we are now, starting early surely wouldn't hurt.
