How to perform automated testing of an entire site after core changes? I'm looking for a module which will test an entire site with each OS update, or Drupal core update. E.g. go through each node and let me know there are any 404 returned for JS or CSS files, broken links, any white screens of death, etc. And if possible if the response time of the site has drastically decreased.

I've done some search and can I only see references to SimpleTest used or unit testing. I'm looking at using Selenium at the moment.

How are other people testing sites after a core changes?
http://drupal.org/project/simpletest - it provides essentially the same testing API as the core D7 module and you still have to write the tests yourself. There is also http://drupal.org/project/simpletest_automator that apparently will help you 'record' your actions on a site into a SimpleTest for you.
