1of 30 StarWest 2006 Agenda

• How I discovered Ruby/Watir • An introduction to a scripting language called Ruby • An introduction to a Ruby library called WATIR • Examples of exploring Ruby/Watir features using IRB • Eclipse and other IDEs • Summary

2of 30 StarWest 2006 Discovery of Ruby/Watir • Change - From Waterfall to Agile • In search of Open Source Automation Tools • StarWest 2005 - Intro to Ruby/Watir • WATIR User’s Guide • My First Ruby/Watir test cases

3of 30 StarWest 2006 Introducing Ruby • Open source • Purely object oriented • Multithreaded • Interpreted scripting language • Highly portable

4of 30 StarWest 2006 Introducing WATIR • WATIR Library • Drives Internet Explorer via COM Objects • WATIR and IRB (Interactive Ruby Shell) • Test Execution in background

5of 30 StarWest 2006 Where to begin • WATIR User Guide: http://wtr.rubyforge.org/watir_user_guide.html – Installation – Unit Tests and Examples – Developing Test Cases – Interacting/Manipulating Web Pages – Using IRB and WATIR

6of 30 StarWest 2006 One-Click Ruby and WATIR Installer

7of 30 StarWest 2006 Prepackaged Ruby Editors • Includes Editors

– Free Ride – Ruby built IDE

– SCite – Text Editor

8of 30 StarWest 2006 WATIR Basics •Get IE instances ie = IE.new() ie.goto(“www.form.com”) • HTML Source is the key to using WATIR and IE to interaction with web pages • Set Text Field ie.text_field(:name, “email”).set(“some text”)

14 of 30 StarWest 2006 Example of Refactoring test code

15 of 30 StarWest 2006 Benefits of Refactoring • Code Reuse – e.g. asserts and logging embedded in method • Simplifies Scripting – e.g. set text field – with single call and; – Assert field set correctly – Log actions to console

16 of 30 StarWest 2006 Results

17 of 30 StarWest 2006 IRB – Interactive Ruby • Console based – single line execution

• Ruby playground – experiment and learn the features of Ruby

• IRB and WATIR – learn how to use WATIR to drive IE

• Test development – great tool to help develop test scripts
