I’ve released the 0.5 version of my open source software WebWalker. It’s written to test websites. It “auto-magically” goes from page to page that you tell it to, simulating someone clicking buttons, filling in information, opening URLs, falling asleep (seriously! it can sleep) and checking to make sure the right page has loaded. It can be used in limited way to load-test websites as well.
