Cucumber

01. Install JRuby

$ rvm install jruby$ rvm jruby

02. Install Cucumber and Selenium

$ gem install cucumber$ gem install selenium-client

03. Write a feature

Feature: Google homepage testing

Scenario: Title of Google homepageGiven that I am on the browser start pageWhen I go to the website www.google.com.brThen the title of page should be "Google"

Understand:

A feature has many scenarios.

A scenario has many steps.

04. Define the steps using Ruby and Selenium

05. Run the tests

$ cucumber

in Java?

You can! ;)
