Selenium 2 is out and integrates WebDriver with Selenium, obsoleting Selenium Remote Control. See the official announcement.We have used Selenium RC in our customer projects from two programming languages: Java and Python. The Selenium 2 release brings in the WebDriver interface for these two languages, plus C# and Ruby.
WebDriver originated from Google (see this announcement) and it’s great to see the two premier Open Source web testing tools getting integrated together.
