DESCRIPTION
Web Application Test In Ruby, is a testing framework for the web applications. Since it's built on ruby it would take the advantage of object oriented principles of ruby and makes the regression/functional testing very very simple. This presentation aims to introduce the WATIR, assists in installing and also testing with a simple test case.

PrerequisitesCan you believe you really don’t need any
special skills to implement this!
What is WATIR?open-source functional testing tool for web-
applicationsSimulate the user actions (filling/submitting
forms…)Drives Internet Explorer browser
FireWatir – for FireFoxRuby based
Various assertions (content-based)Connects to databasesReading data filesExporting data (xml/html/excel…)
Why use WATIR?FreePowerfulSimple (easy to use and learn)Excellent SupportStrongest Presence
Watir/Watin/Watij [Web Application Testing In Ruby/.NET/Java ]
Huge resource of supporting tools – Firewatir, Watir Recorder ++, Wet, Cubictest,
Visual Studio
Is not?Watir is not a record/playback tool.
However, there are several recorders “out there”WatirMakerWatir WebRecorderWebmetrics RIA Script Recorder (most recent discussion…
they are considering open sourcing their application)
Watir is not a link checkerHowever, 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.(underwork)

Installing: Windows Install Ruby: Use the Ruby one-click installer for windows Install the latest gem watir (ruby packages are called gems)
gem install watirAnd you find the following gems installing…
Successfully installed xml-simple-1.0.11Successfully installed s4t-utils-1.0.4Successfully installed builder-2.1.2Successfully installed user-choices-1.1.6Successfully installed commonwatir-1.6.2Successfully installed firewatir-1.6.2 (to support Firefox)Successfully installed watir-1.6.2Successfully installed win32-api-1.3.0-x86-mswin32-60Successfully installed windows-api-0.3.0Successfully installed rubyforge-1.0.210 gems installed
Installation done… let’s move ahead
What Next?Since we are here to test the web-
application Navigate the browser?Find elements on the page?Interact with elements on the page?Check output on the page?Create and use Methods?Create formal test cases?
Step by StepNavigate to the browser#Always Load the Watir library at the top of
your scriptrequire ‘watir’
Start IE and navigate to a given/different URLIE = Watir::IE.start(‘http://www.qvnatel.com’)IE.goto(“http://free-opensource.qvantel.net/
mediawiki//index.php/Main_Page ”)IE.close
Finding <HTML> ElementsTextBox IE.text_field(how, what)
Button IE.button(how, what)
DropDownList IE.select_list(how, what)
CheckBox IE.checkbox(how, what)
RadioButton IE.radio(how, what)
HyperLink IE.link(how, what)
Form IE.form(how, what)
Frame IE.frame(how, what)
And many, many more (div, label, image, etc…)…
Interacting with Elements#Set the text field (or text area) specified name
specified value. ie.text_field(:name,'name').set('value')
#Sets the select with to the specified valueie.select_list(:name,'name').select('value')
#Click the button with the specified value (label)ie.button(:value,'value').click
#Clicks the link matching 'text' ie.link(:text,'text').click
#Accessing elements in a "frame" or "iframe"ie.frame(:name,"someFrame").text_field(:name,'na
me').set('value')
Closer view
browser.button(:value, "Click Me").click
[Variable] . [method] (: [element] , “ [unique identifier]” . [method]
Checking Output
#Get the title of the pageie.title
#Get all the text displayed on the pageie.text
#Get all the HTML in the body of the pageie.html
#Return true if ‘text’ is displayed on the pageie.contains_text('text')
Ruby advantageSince WATIR is ruby based web application
testing framework, we can customize the script according to our needs.
Taking Ruby’s Object Oriented concepts, create more dynamic/customized scripts
Use classes & methods effectivelyAccess even the database to validate the
data
Test::Unit Assertions
Methods #Here is an example method for logging into a web
application. Its two parameters are a user and password (both of which have defaults). It returns an instance of IEdef login(user=“test_admin”,password = “Password123”)
ie=Watir::IE.start(‘http://someURL.com/login’)ie.text_field(:name,/user/i).set(user)ie.text_field(:name,/password/i).set(password)ie.button(:value,/login/i).clickreturn ie
end
#Now we can easily login with the default user.. ie = login #or with a unique user ie = login(“Fred”,”flinstone”)
Full Fledge Test Case require 'test/unit' #includes Ruby's test case functionality require ‘util’ #Assuming our login method is saved in util.rb
#Test cases are contained within classes which extend Ruby’s base test case classclass MyTest < Test::Unit::TestCase
def setup #Optional, will be run before each test method. @ie = login() #call our login function.
end
def test_some_link #Test methods must begin with "test_“@ie.link(:text,”some_link”).click #click on some link
#verify that the proper page loadedassert(@ie.contains_text(“My Some Link Page”))
end
def teardown #Optional, will be run after each test [email protected]
endend
Installing: Ubuntu Install Ruby:
sudo apt-get install ruby Install the latest gem firewatir (ruby packages are called gems)
sudo gem install firewatirAnd you find the following gems installing…
Successfully installed xml-simple-1.0.11Successfully installed s4t-utils-1.0.4Successfully installed builder-2.1.2Successfully installed user-choices-1.1.6Successfully installed commonwatir-1.6.2Successfully installed firewatir-1.6.2Successfully installed rubyforge-1.0.27 gems installed (3gems to support IE/Windows environment are not
installed)
Installation done… let’s move ahead
Tweaks/TipsWhile working on Linux platform need to
specifyrequire “rubygems” at the top of test case
ff = FireWatir::Firefox.newStart firefox in jssh mode
For Windows:Close instances of firefox (if any)Type “firefox.exe –p –jssh” in the “Run”
ie = Watir::IE.new
ScopeUsing Watir for all web applicationsIntegrate it with Automation/Building
