Dojo has its own unit test system called DOH (Dojo Objective Harness) which can be run headless (and integrated in Java builds) for components which are not widgets and inside a Unit-test web page. DOH is fairly simple to use for custom components as well.
Recently Dojo added a event-playback package called robot, which gives Selenium-like testing functionality as well.
