I tried Selenium 2.0 (documentation says it's using WebDriver) as so:
java -jar selenium-server-standalone-2.0a1.jar -htmlSuite "*firefox" ...
but it seems that the WebDriver backend isn't used (especially since I haven't installed any Firefox plugin)? All Selenium 2.0 documentation uses Java interface, but it seems that using HTML suite uses the classic Selenium backend?
I've found no documentation on how to set up things for htmlSuite, but using the "headless" (HtmlUnit) version is totally OK (I don't need Firefox).
Edit: Selenium says RemoteWebDriver instances should connect to: http://...:4444/wd/hub
when starting up... Any idea of what to do and how?
Edit 2: Rewriting the test in Java using WebDriverBackedSelenium works. Thus the problems arise from htmlSuite not implemented using WebDriverBackedSelenium?
