Jari Bakken just released Watir on WebDriver.

On Windows, install it with

gem install selenium-webdriver
gem install watir-webdriver --pre

and use it with

require "rubygems" # optional
require "watir-webdriver"
browser = Watir::Browser.new(:firefox)

Supported browsers are Internet Explorer (:ie, :internet_explorer), Firefox (:ff, :firefox), Chrome (:chrome) and RemoteWebDriver Server (:remote).

Update 1: as Steve suggested, I have tried it on RubyInstaller.

Install RubyInstaller, DevKit and all required gems and it just works!

gem install selenium-webdriver
gem install watir-webdriver --pre
gem install win32-process

Update 2: It works on Mac.

My Mac came with Ruby and RubyGems installed, so it was just:

sudo gem install selenium-webdriver
sudo gem install watir-webdriver --pre

Update 3: It works on Ubuntu Linux.

My Ubuntu did not have Ruby and RubyGems installed.

Install Ruby with:

sudo apt-get install ruby-full

You can install RubyGems with:

sudo apt-get install rubygems

but Jari said it would be better to install it from source. Downland the latest RubyGems tgz or zip file (rubygems-1.3.5.tgz and rubygems-1.3.5.zip at the moment), extract it, open Terminal in extracted folder and run:

sudo ruby setup.rb

Install watir-webdriver:

sudo gem1.8 install selenium-webdriver
sudo gem1.8 install watir-webdriver --pre
