What is WATIR?

Web Application Testing In Ruby

It is a library for the Ruby language which drives Firefox,
Google Chrome, Internet Explorer the same way people
do;

clicks links,

fills in forms,

and presses buttons.

Watir can also check results, such as whether expected
text appears on the page.

It can be used to test all types of web applications
(ASP.Net, JSP, PHP, Rails, etc…)

Open Source – written by Bret Pettichord, Paul Rogers and
many other contributors.

What WATIR is not...

Watir is not a record/playback tool.

However, there are several recorders “out there”

WatirMaker

Watir WebRecorder

Webmetrics RIA Script Recorder (most recent discussion…they
are considering open sourcing their application)

Watir is not a link checker.

However, you can easily write your own link checker and customize
it to your specific needs.

Watir is not a test case management tool.

However, you can write one in Ruby if desired.

Doesn’t test Flash or Applets.

What is Ruby?

Full featured Object Oriented scripting language

Made “famous” for it’s web application framework Rails. (Ruby on
Rails)

Interpreted rather than compiled

Written by Matz (Yukihiro Matsumoto)

Started in 1994

Written in C

Will work on any platform that has a C compiler

Windows

Linux

How does Watir works?

Uses the COM interface of Internet Explorer (IE)

Allows an external program to control IE

Similar interfaces exist for Word, Excel, PowerPoint and Outlook.

Full access to the contents of an HTML page

Provides different ways to access objects

Why Watir? (contd...)

As a testing tool: It’s as robust & sophisticated as
‘professional’ tools such as Rational, Mercury & Segue.

As a library of a programming language [Ruby ] : It’s powerful.

(You have the power to connect to databases, read data files,
export XML, structure your code into reusable libraries, and
pretty much anything else you can think of…)

No “Vendor-script”

It’s simple – elegant – INTUITIVE

It has a supportive online community for when you get ‘stuck’.

Development
Environment's(IDE's)
for Ruby
Use any text editor as an IDE:

ScITE (Free)

Included with your ruby download.

Notepad ++(Free)

Eclipse (using RDT Plugin)

http://rubyeclipse.sourceforge.net/

Using Ruby's
Interactive Command
Interpreter (IRB)

What is it?

Interactive Ruby.

It evaluates Ruby expressions from the Terminal.

Used To:

Run quick experiments to see if things will work in your tests
– irb (main) : 001 : 0> require 'watir'.
– irb (main) : 002 : 0> require 'watir-webdriver'.
– irb (main) : 003 : 0> browser = Watir::Browser.new'.
– irb (main) : 004 : 0> browser.goto 'http://google.com'

Let's Get Started..
It’s time to turn on
the Watir!

Anatomy of Watir
Script
# Loads the watir gems
require 'watir'
# Loads all the gems required to drive firefox and chrome
require 'watir-webdriver'
# To open a new browser(firefox)
browser = Watir::Browser.new :firefox
# Navigate to the below URL
browser.goto 'http://ourgoalplan.com/'
# Identify the field to which data is to be inserted and enter the value
browser.text_field(:name => 'txtName').set 'subhasish.pattanaik'
browser.text_field(:name => 'txtPassword').set 'subh_2727'
# To click the button
browser.button( :id => 'btnLogin').click
# To enter the goals in the Text area
browser.text_field( :id => 'ucAddGoal_txtAddGoal').set '[CIRRATA-
WP] : TESTING + ISSUES REPORTING[EST - 2HRS]' + "n" +
'[COMMETTE] : TESTING + ISSUES REPORTING[EST - 2HRS]'
# To click on the Add Goal button
browser.button( :id => 'ucAddGoal_btnAddGoal').click

Use Watir

Using Watir API is very easy.

Reference the Watir API using the keyword 'require' and start
coding.
require 'watir'
require 'watir-webdriver'
browser = Watir::Browser.new :firefox

Web Pages are all
about Objects

Web pages are developed with objects:

Links, buttons, tables, drop-down boxes, forms, frames, etc.

Watir scripts need to access these objects &
manipulate them just as a user would.

Clicking, submitting, typing, selecting, etc…

Manipulating Web Page
Objects:Link

Objects:Checkbox

Objects:Radio Buttons

Objects:Selection Boxes

Objects:Text Fields

Objects:Buttons

A Closer Look... at the
structure
browser.button(:value, "Click
Me").click
[Variable] . [method] (: [element] , “ [unique identifier]” . [method]

Test Automation is
MORE than Identifying
Objects

Identifying objects is currently the most time
consuming part of creating your test scripts…

However, after your objects have been identified
& manipulated: you want to “Test” them!

You’ll want to create “PASS” or “FAIL”
scenarios.
…This is the most sophisticated part
of your scripts. Will learn more on this
in next seminar...

Congratulations!
You are on your Way
…to programming the Ruby-Watir way !!
