Testing Javascript

Hey guys,

Sometime back in 2006 I worked on some Javascript testing stuff with
Divmod. I'm vaguely interested in what's happened with it, but that's
not the main point of this email.

What I'd really like to know is what's your overall strategy to
testing Javascript on your websites. What tools do you use? Do you
have it integrated into your main buildbot runs? Is it fast? What are
your main gripes with what you've got?

cheers,
jml
