Interesting development in Watir world but not a completely unanticipated one. I started playing around with using WebDriver as platform for Watir in the form of FireDriver and ChromeWatir.
Yesterday Jarib has released a Watir abstraction on top of WebDriver. I am planning to move the effort of working on ChromeDriver to Watir-WebDriver which has ChromeDriver in it.
Installation of Watir-WebDriver
> sudo gem install selenium-webdriver
> git clone git://github.com/saivenkat/watir-webdriver.git
Example code in watir-webdriver (ChromeDriver)
browser = Watir::Browser.new(:chrome)
browser.text_field(:name, "q").set "Watir"
The code is same as Watir except the driver changes internally.
The repo is in http://github.com/saivenkat/watir-webdriver. Feel free to fork and enjoy...
