No, it's not all :-). See trunk/tests/khtmltests/, in particular the 
regression directory, which can be used with the testregression tool 
automatically. To build testregression, do "make testregression" in your 
KHTML build dir. (Note that you need to have KHTML built debug for it to 
work). There are about 7275 automated testcases. Some (most?) come from 
outside sources, such as official W3C testsuites, and Mozilla testsuite; the 
rest are often from bug reports or developers... Let me know if you need any 
help with testregression, it can be a bit of a pain to get it working the 
first time.

Not sure who considers XMLHttpRequest his baby. I think Dawit Alemayeho 
<adawit at kde.org> did most of the stuff lately, and I don't know whether he 
follows this list. So if you don't get a response, might want to drop him a 
not or something.

Also, if you plan on doing lots of this stuff, I'd suggest getting an SVN 
account.

Thank you for your contribution,
Maks.
