  11. 11. What is Behavior Driven Development (BDD) BDD AUTOMATION TESTING WITH CUCUMBER 11
  12. 12. 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
  13. 13. 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".

  14. 14. 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
  15. 15. 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 BDD AUTOMATION TESTING WITH CUCUMBER 15
  16. 16. 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. BDD AUTOMATION TESTING WITH CUCUMBER 16
  17. 17. What is Cucumber BDD AUTOMATION TESTING WITH CUCUMBER 17
  18. 18. 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 18

  21. 21. 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 AUTOMATION TESTING WITH CUCUMBER 21

  23. 23. 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 23

  29. 29. APPENDIX APPENDIX –PAGE OBJECT PATTERN 29
  30. 30. UI Test Setup with Page Object Pattern APPENDIX –PAGE OBJECT PATTERN 30
  31. 31. 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
  32. 32. 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) APPENDIX –PAGE OBJECT PATTERN 32
