As far as I can tell, while there are several, there are none that are 
actually Just Work good.  It seems to be an area still in flux, people 
coming up with an open source way to do that that is reliable and easy 
to use and just works.

The main division in current approaches seems to be between: 1) Trying 
to automate _actual browsers_ so you know you've tested it in the real 
browsers you care about (the headaches of this are obvious, but people 
are doing it!), and 2) Using a headless javascript browser that can be 
run right on the server, to test general javascriptyness but without 
testing idiosyncracies of particular browsers (I would lean towards this 
one myself, I'm willing to give up what it gives up for something that 
works a lot simpler with less headaches).

I've heard good things about celerity (http://celerity.rubyforge.org/) but I believe it only works with jruby, which has been a barrier to getting started with it so far. Anyone have other tools to suggest? Is anyone doing javascript testing in a way they like? Feel like sharing?
