Introduction

Watir(Web Application Test in Ruby), pronounced water, is an automated test tool which uses the Ruby scripting language to drive the Internet Explorer web browser. It allows you to write tests that are easy to read and maintain. It is simple and flexible. Watir was primarily developed by Bret Pettichord and Paul Rogers. It drives Internet Explorer, Firefox, Chrome, Opera and Safari, and is available as a RubyGems gem. Watir is a toolkit for automated tests to be developed and run against a web browser.

Watir project consists of several smaller projects. The most important ones are watir-classic, watir-webdriver and watirspec.

Watirspec

Watirspec is executable specification of the Watir API, like RubySpec is for Ruby.

Make It Run

All examples are designed to work on the live Watir demo form: http://bit.ly/watir-example.

Run in .rb

You can require Ruby Watir gem first via the -rubygems command line option or by using the RUBYOPT environment variable. You can also require it manually in your script: require 'rubygems'

Including Watir gem to drive Internet Explorer on Windows require 'watir'

Including Watir-WebDriver gem to drive Firefox/Chrome on Windows/Mac/Linux require 'watir-webdriver'

Starting a new browser & and going to our site browser = Watir::Browser.new browser.goto 'http://bit.ly/watir-example'

Setting a text field

browser.text_field(:name => 'entry.0.single').set 'Watir'

Setting a multi-line text box

browser.text_field(:name => 'entry.1.single').set "I come here from Australia. \n The weather is great here."

Setting and clearing a radio button

browser.radio(:value => 'Watir').set
browser.radio(:value => 'Watir').clear

Setting and clearing check boxes

browser.checkbox(:value => 'Ruby').set
browser.checkbox(:value => 'Python').set
browser.checkbox(:value => 'Python').clear

Clearing, getting and selecting selection list values

browser.select_list(:name => 'entry.6.single').clear
puts browser.select_list(:name => 'entry.6.single').options
browser.select_list(:name => 'entry.6.single').select 'Chrome'

Clicking a button

browser.button(:name => 'submit').click

Checking for text in a page

puts browser.text.include? 'Your response has been recorded.'

Checking the title of a page

puts browser.title == 'Thanks!'

Run in Rspec

RSpec is a Behaviour-Driven Development tool for Ruby programmers. BDD is an approach to software development that combines Test-Driven Development, Domain Driven Design, and Acceptance Test-Driven Planning. RSpec helps you do the TDD part of that equation, focusing on the documentation and design aspects of TDD. The following code demonstrates using Watir and a basic RSpec example. More Info.[1]

1. Install

gem install rspec

2. Example

rspec test_spec.rb

will execute the following rspec example …

test_spec.rb

require "rubygems" require "rspec" require "watir-webdriver" describe "google.com" do

 let(:browser) { @browser ||= Watir::Browser.new :firefox } 
 before { browser.goto "http://google.com" } 
 after { browser.close }
 if "should search for watir" do
   browser.text_field(:name => "q").set "watir"
   browser.button.click 
   browser.div(:id => "resultStats").wait_until_present
   browser.title.should == "watir - Google Search"
 end

end
