Ask HN: What tools do you use to automate the testing of your websites?
From unit testing to link checkers. Is it possible to automate testing of display and layout issues from release to release?

http://seleniumhq.org/ is great for system testing. Easy to start using with the firefox plugin (selenium IDE), more advanced features (Selenium RC, Grid) and tests can be written in a number of languages.
http://browsershots.org/ is useful for checking layout on every browser/os combination imaginable.
