watir on steroids / jruby wrapper for htmlunit

branch: master



Celerity is a JRuby library for easy and fast functional test automation for web applications.

Celerity is a JRuby wrapper around HtmlUnit – a headless Java browser with JavaScript support. It provides a simple API for programmatic navigation through web applications. Celerity provides a superset of Watir's API.


  • Fast: No time-consuming GUI rendering or unessential downloads

  • Scalable: Java threads lets you run tests in parallel

  • *Easy to use*: Simple API

  • Portable: Cross-platform thanks to the JVM

  • Unintrusive: No browser window interrupting your workflow (runs in background)


  • JRuby 1.2.0 or higher

  • Java 6


jruby -S gem install celerity

or from GitHub (updated frequently)

jruby -S gem install jarib-celerity


require "rubygems"
require "celerity" 

browser =
browser.text_field(:name, 'q').value = 'Celerity'
browser.button(:name, 'btnG').click

puts "yay" if browser.text.include? ''
