“However, we took a different approach to dispatching events: instead of using synthetic events, we used the cross-browser and cross-platform Java applet technology to place real events on the native event queue, as if a real person performed the action. This means that when you use doh.robot to execute your unit tests, browsers will trust the events doh.robot creates from your commands and will handle any and all contingent events for you. So when you tell doh.robot to send a Tab keypress, you can fully expect the Tab to move focus to the next element in the Tab order, as if a real user pressed Tab. And when you tell doh.robot to click an element, you can fully expect to get the onmouseover before the onmousedown, as well as all of those hundreds of onmousemoves a real user would generate in between. When you use the DOH test runner in conjunction with doh.robot, you can easily automate and report the results of numerous accessibility and UI unit tests that would otherwise require manual, visual inspection by a real person.”

Looks pretty sweet, I’ve always been skeptical of (and had trouble with) the UI testers that synthesized events. I think the API needs a little help, but I expect this to be huge over the next few months. Dojo is really offering a lot of well engineered features.
