Specific example of an requirement
Feature: login to the system.
Asa user,
I want to login into the system when I provide username and password.
Scenario:login successfully
Giventhe login page is opening
WhenI input username into the username textbox
AndI input valid password into the password textbox
AndI click Login button
ThenI am on the Home page

driver.findElement(By.id("email")).clear();
driver.findElement(By.id("email")).sendKeys("bddtest@yahoo.com");

What is Behavior Driven Development (BDD)
BDD AUTOMATION TESTING WITH CUCUMBER 11

Definition:
Behavior-driven development (or BDD) is an agile software development technique that encourages collaboration between developers, QA and non-technical or business participants in a software project.
BDD AUTOMATION TESTING WITH CUCUMBER 12

More specific:
It’sallaboutGiven,WhenandThen–Mapseasilytouserstories
Extends Test Driven Development (TDD) by utilizing natural language that non-technical stakeholders can understand.
Encourages collaboration between Domain experts, Business Analysts, QA Engineers, Developers & Business Owners / Stakeholders
Driven by Business Value and finally, with the aim of delivering "software that matters".

BDD scenario detail:
A description of each specific case of the narrative. Such a scenario has the following structure:
BDD AUTOMATION TESTING WITH CUCUMBER 14

Mapping User storiesto BDD scenarios:
User story
BDD scenario
As a calculator user, I want to add two numbers so that I can do addition.
Given I have two numbers 500 & 500 When I add them upThen I should get result 1000
As a Math teacher, I want to automate marks sorting process so that I can declare top 5 in my class.
Given a list of numbersWhen I sort the listThen the list will be in numerical order
As a QA engineer, I want to check a critical feature so that I can do smoke test easily.
Given I visit Google.comWhen I type ‘TestingWhiz' as a search string
Then I should get search results matching TestingWhiz

Tooling principles:
The tooling reads a specification document.
The tooling directly understands completely formal parts of the ubiquitous language (such as the Given keyword in the example above).
Each individual clause in a scenario is transformed into some sort of parameter for a test for the user story.
The framework then executes the test for each scenario, with the parameters from that scenario.

What is Cucumber
BDD AUTOMATION TESTING WITH CUCUMBER 17

Cucumber definition:
From Wikipedia, Cucumberis asoftwaretool thatcomputer programmersuse for testing other software. It runs automatedacceptance testswritten in aBehavior-Driven Development(BDD) style.

BDD AUTOMATION TESTING WITH CUCUMBER 20

Example of BDD scenario:
Feature: login to the system.
Asa user,
I want to login into the system when I provide username and password.
Scenario:login successfully
Giventhe login page is opening
WhenI input username into the username textbox
AndI input valid password into the password textbox
AndI click Login button
ThenI am on the Home page

BDD Scenario with parameters:

How Cucumber works:
BDD AUTOMATION TESTING WITH CUCUMBER
Given/^I launch "([^"]*)" page$/ do |page|
visit(page)
End
When/^I fill in "([^"]*)" with "([^"]*)"$/ do |field, value|
fill_infield, :with => value
end

APPENDIX –PAGE OBJECT PATTERN 29

UI Test Setup with Page Object Pattern
APPENDIX –PAGE OBJECT PATTERN 30

PAGEOBJECTPATTERN
Page Object Pattern is UI Automation Test good practice.
It represents the screens of Web app as a series of objects and encapsulates the features represented by a page.
It allows us to model the UI in our tests.
A page object is an object-oriented class that serves as an interface to a page of your AUT.
APPENDIX –PAGE OBJECT PATTERN 31

Page Object Pattern advantages:
Reduces the duplication of code
Makes tests more readable and robust
Improves themaintainabilityof tests, particularly when there is frequent change in the AUT.(Useful in Agile methodology based projects)
