Something about functional test

Seems that new version of Selenium (2.0+) is not support PHP now

and old version(1.0, 1.01) is not support new version firefox(FF 3.5 or below).

How to do a functional test with modern tools?

Selenium Server (v2.x) is backward compatible with Selenium RC server (v1.x)

from selenium download page

I’ve tried functional testing (with WebTestCase) using selenium-server-standalone-2.8.0.jar and Firefox 7 and it works.
