“Fake is a new browser for Mac OS X that makes web automation simple. Fake allows you to drag discrete browser Actions into a graphical Workflow that can be run again and again without human interaction. The Fake Workflows you create can be saved, reopened, and shared.”
Fake could make testing webapps fairly easy and repeatable in environments where Selenium is unavailable or where WebKit is the target renderer, eg. for websites built for touch devices.
