THE RUBY LANGUAGE

1. WATIR – Web Application Testing in
Ruby

What is Watir and why should we use it?
•Free
•Powerful
•Simple
•Excellent Support
•It uses Ruby
•Broad usage
• Multiple browsers
• Windows/tabs.
• JavaScript
• Frames
• Modal dialogs.
• Invisible runs
• Screen Capture
• … anything you can think of 

HOW WATIR WORKS?

HOW TO GET STARTED WINDOWS
MAC
1. Download and install Ruby.
2. Install rubygems: gem update --
system
3. Install DevKit
4. Download and install
ChromeDriver.
5. Install Watir-Webdriver: gem
install watir-webdriver
6. Open CMD, type: irb
7. Type: require 'watir-webdriver'
8. Type: browser =
Watir::Browser.start
'iasi.codecamp.ro'
1. Download and install Ruby.
2. Install Watir-Webdriver: gem install
watir-webdriver
3. Open CMD, type: irb
4. Type: require 'watir-webdriver'
5. Type: browser = Watir::Browser
.start 'iasi.codecamp.ro'

READY FOR SOME CODE?

OPEN A WEB PAGE AND SHOW TITLE AND TEXT
• require 'watir-webdriver'
• b = Watir::Browser.new :chrome
• b.goto 'iasi.codecamp.ro'
Returns current title of the page
• b.title
Returns current text elements of the
page
• b.text

THE DOM LOCATORS TREE OF LIFE

TextBox b.text_field(:name,’n’).set ’a’
Button b.button(:text, /text/).click
DropDown b.select_list(:id, ’id’).set
CheckBox b.checkbox(:class, ’cl’).click
Radio b.radio(:class, ’cl’).click
Link b.link(:href, ’URL’).click
Form b.form(:name, ’n’).set ’Value’
Frame b.frame(:id, ’frame1’).use
And many more (div, label, image, etc)…

INTERACTION WITH DOM
Interaction with DOM
• b.link(:text, 'Sponsors').click
Small conditional validation test
if b.text.include? 'Probably the largest IT conference in
Romania!'
puts 'Test passed.'
else
puts 'Test failed.'
end

COLLECTIONS OF ELEMENTS
Returns all text links of the page
•b.links.each {|x| unless x.text.empty? or
x.text.nil?; puts x.text; end }
Returns all text of the page which is enclosed in
<span> tags.
•b.lis.each {|x| unless x.text.empty? or x.text.nil?;
puts x.text; end }
Returns all images url’s of the page.
•b.imgs.each {|x| puts x.src }

Writes all images’ url’s to a new array
a = Array.new
b.imgs.each {|x| a.push(x.src) }
puts a

DEBUGGIN WITH IRB
IRB = Interactive Ruby Shell;
Command line-like interface that allows immediate
running of Ruby script. Great for debugging one line
at a time, rather then having to run through an entire
script. Great for testing single lines

2. ANY GUI AUTOMATION –
AUTOIT AND SIKULI
Simple AutoIT Example Simple Sikuli Example (on jRuby)

3. WEB SERVICES AUTOMATION USING
RUBY

3.1 REST
• First you will have to install a REST client gem:
gem install rest-client
• Then use it like this:
require 'rest-client'
RestClient.get 'http://services.groupkt.com/country/get/all’
RestClient.post 'http://example.com/resource', :param1 =>
'one', :nested => { :param2 => 'two' }
RestClient.delete 'http://example.com/resource’
For more details: http://www.rubydoc.info/gems/rest-
client/1.8.0

3.2 SOAP
•First you will have to install a SOAP client
gem:
gem install savon
•Then use it like this:
require ’savon'
client =
Savon.client(wsdl:'http://service.example.com?wsdl')

client.operations # => [:find_user, :list_users]
# call the 'findUser' operation
response = client.call(:find_user, message: { id: 42 })
response.body
# => { find_user_response: { id: 42, name: 'Hoff' } }
For more details:
http://www.rubydoc.info/gems/savon/2.11.1

SOAP Operations

4. DATABASES

Connecting Ruby to Mysql db
•First you will have to install a db client (If
needed):
gem install mysql
•Then use it like this:
db_host = "localhost"
db_user = "root"
db_pass = "root"
db_name = "your_db_name"
• client = Mysql::Client.new(:host => db_host,
:username => db_user, :password => db_pass,
:database => db_name)

Executing the query
•client = Mysql::Client.new(:host =>
db_host, :username => db_user,
:password => db_pass, :database =>
db_name)
•cdr_result = client.query(
'SELECT * from your_db_table_name')
Other DB adapters for ruby: https://www.ruby-
toolbox.com/categories/SQL_Database_Adapters

5. BDD: CUCUMBER & RSPEC
Install the necessary gems by running:
• gem install 'cucumber'
• gem install 'watir-webdriver'
• gem install 'rspec-expectations‘
Setup Env.rb (next slide)
Create GoogleSearch.feature:
Feature:
"When I go to the Google search page, and search for an item, I
expect to see some reference to that item in the result summary.“
Scenario: 1. Search BDD in Google (Positive)
Given that I have gone to the Google page
When I add "BDD" to the search box
And click the Search Button
Then " behavior-driven development" should be mentioned in the
results

CREATE CODE FOR YOUR FEATURES
Given /^that I have gone to the
Google page$/ do
@browser.goto('www.google.com'
)
end
When /^I add "(.*)" to the
search box$/ do |item|
@browser.text_field(:name,
'q').set(item)
end
And /^click the Search
Button$/ do
@browser.button(:name,
'btnG').click
End
Then /"(.*)" should be
mentioned in the results/ do
|text|
@browser.text.should =~
/#{text}/
End
Run using the following command:
cucumber GoogleSearch.feature

RAKE – RUNNING SCRIPTS GROUPED IN TASKS.
require 'rspec/core/rake_task'
RSpec::Core::RakeTask.new(:spec) do |t|
t.pattern = FileList['spec/*_spec.rb']
t.rspec_opts = '--format html >
./results.html'
end
task :default => :spec

RSPEC AND EXTENSIVE LOGGING

6. CONTINUOUS INTEGRATION WITH JENKINS

7. INTEGRATION WITH SAUCE LABS

Sublime
Notepad++
TOOLS FOR ACCESSING DOM ELEMENTS USEFUL TOOLS/IDEs
FireBug
Xpath Checker
WATIR::SupportsSubElements
IE Developer Tool bar
