The document discusses Behavior Driven Testing (BDT) in Agile methodologies, emphasizing the importance of effective testing strategies such as the test pyramid and BDT principles. It provides examples of test scenarios and highlights the role of automation in facilitating Agile practices while warning of potential pitfalls. Additionally, it outlines tools and frameworks that support BDT, along with a case study demonstrating the functionality of a flight booking system.

- 15. Expected Func/onality: The customer should be able to withdraw money from his account via an ATM machine
- 16. BDD Example: Given the account has balance of 5000 When the customer requests 1000 Then the account is debited by 1000
- 17. BDT Example: Given the account is in credit And the dispenser contains cash When the customer requests cash Then ensure the account is debited And ensure cash is dispensed And ensure the card is returned
- 18. New Expected Func/onality: The customer should be able to withdraw money from his account only if his card is valid
- 19. BDT Example -‐ updated: Given the account is in credit And the card is valid And the dispenser contains cash When the customer requests cash Then ensure the account is debited And ensure cash is dispensed And ensure the card is returned
- 20. Case Study
- 22. Requirements • Guest User is able to search for a flight for a single traveller • Ability to specify contact informa*on for person booking the flight
- 23. Search Contact Search Results Informa/on
- 26. Contact Details
- 27. Test specifica*on styles • Impera*ve • Declara*ve
- 28. Impera*ve style Given I am a guest user on the Indigo home page And I select “round” trip op*on And I select “Pune” from the origin dropdown And I select “Bangalore” from the des*na*on drop down And I select departure date as “5 July 2012” And I select returning date as “25 July 2012” When I click on Search Then I should see the search results page And I should see at least 1 op*on for my criteria ...
- 29. … When I select the “first” op*on Then I am on the Contact Informa*on page When I enter first name as “foo” And I enter last name as “bar” … … And I click the “Select and Con/nue” buCon Then I should be on the next page
- 30. Declara*ve style Given I am a guest user When I search for flight op*ons for a “one-‐way” trip for “1” “Adult” from “Delhi” to “Bangalore” And I select the “first” flight And I enter “valid” contact details for “traveller1” Then I am able to Save and Con*nue

- 32. What does BDT do for me?
- 33. What BDT does NOT do for me? • Replace tes*ng granular func*onality – ONLY when it has just been developed
- 34. Steps to follow to implement BDT
- 39. Current state Tests running on Hudson / Jenkins Since 1st test was automated Feature files 33 Scenarios 65 Smoke tests execu*on *me 15 minutes Regression tests execu*on *me 45 minutes Test case repository (manual + Cucumber .feature files with automated) appropriate tagging Project Management tool Mingle
