HtmlUnit is quite different. It is a language/framework agnostic way to
test any webapp *including* the app's JS. All of this, even the JS, is
in memory and does not require a browser just like webrat. It does the
JS by using Rhino, Java's implementation of JS. At the moment, webrat
is tied to rails integration testing framework (their are forks that
allow merb testing as well that I have used successfully.) As Joseph
said their is currently some work to wrap the webrat API around
Selenuin, mechanize, etc, that would break it's dependence on the
integration testing framework in rails. Having it tied to the
integration framework does give you some flexibility though and is most
To answer your original question on how people are using it... In the
past project I did I ended up with 100+ scenarios all using webrat. We
decided to make the entire site with UJS (unobtrusive JS) which lent it
self to testing it with webrat. The extra JS we added we have not yet
wrapped stories around it so we have a manual testing cycle before each
major deployment. On the current project I'm on we are going to be
using JS heavily and will most likely leverage HtmlUnit (Celerity) in
our stories to keep them all in-memory. If your app is not extremely JS
dependent then I would recommend the UJS + webrat route.

Have you seen Johnson yet?
It's goal is to wrap Mozilla's JS engine written in C, SpiderMonkey, in
ruby. With this equivalent solution in place like Java's Rhino it will
be possible to create an HtmlUnit like testing framwork entirely in Ruby
and perhaps just extend webrat to get JS functionality. I have not yet
realll played around with it and I haven't been able to find any posts
about how to use it.. but it is something to keep your eye on.
Johnson seems young so, as I said earlier, we will probably try to use
the more mature HtmlUnit (a'la JRuby) to do our in-memory JS testing.
