3. About presentation What’s that? Why? Behavior-Driven Development Solutions? Problems? How?

4. Builder xUnit Selenium Typical toolset

5. Business Analyst Test Designer xUnit Solution difficulties Not all people read tests code Developer Test Automation Engineer

6. xUnit Solution difficulties Complex code constructions are hard to maintain If it works don't touch it!

7. xUnit Solution difficulties Low informative report What exactly has happened?

8. How to improve it We gonna make it better

9. It should be clear to everyone We gonna make it better

10. More people should be involved We gonna make it better

11. Profit We gonna make it better

12. New approach? Behavior-Driven Development? Data-Driven Testing Keyword-DrivenTesting Model-Based Testing

13. How about tests like that? Behavior description prior to implementation

14. List of BDD engines NBehave Cucumber Freshen JBehave Behat

15. BDD tests structure Background Feature Given Background When Scenario 1 Then Scenario Scenario 2 Given Scenario N When Then

16. Connections to code Text instruction WhenI log into the system as “login”/”password” Actual Code When/log into the system as “(.*)””(.*)”/do|login,password| app.login( login , password )‏ end Explicit Selenium calls class App def login( username , password )‏ # Some actions end end

17. BDD project structure Main working folder Keyword implementations Core library Initialization module Tests storage

18. What BDD brings? Natural language instructions I can get it!

19. What BDD brings? Reports show steps to reproduce I see where the problem occurs!

20. What BDD brings? Process optimization Run Implement Design Test Automation pipeline On-demand runs Writes user stories BA

21. What BDD brings? Process optimization Run Implement Design Test Automation pipeline On-demand runs Write simple tests Dev

22. What BDD brings? Process optimization Run Implement Design Test Automation pipeline Analyze results Designs tests Tester

23. What BDD brings? Process optimization Run Implement Design Test Automation pipeline Results analysis Implementation & code maintenance ATE

24. Who participates in automation?

25. Stages to framework migration Decompose code by details level Extract Selenium object and wrap it into global object Wrap each function with appropriate keyword Re-design existing tests

26. Framework decomposition We care what we do only We care where we are Business Functions level Pages level We care how to do it Explicit Selenium calls Explicit Selenium calls Core level

27. Framework re-organization to BDD Code layer Business Functions level Pages level Global Selenium Object Core level

28. Implementation layer BF level Pages level Core level Tests layer Framework re-organization to BDD When /click on “(.*)” element/ do |locator| selenium.click( locator ) end Code layer BF level Pages level When I click on “Test” element Core level Selenium selenium.click( locator );

29. Collect all resources Initialize shell Global Selenium Object Run instructions Finalize execution Generate report Selenium place selenium.start() Start Call Command Stop DefaultSelenium.new selenium.stop()

30. There’re still some questions How to avoid duplicates? How to locate elements? How to store values? How to use random data?

31. UI elements mapping. What for? Which way is more reliable and informative? When I click on “Search" link When I click on "//div[@id='some_div']/button[text()='Add']" button When I click on "Add" button on "Home Page" When I create “test.txt" file in “%USERPROFILE%” folder When I create “test.txt" file in “C:Temp” folder

32. Page Title Name Item Alias Locator UI elements mapping. How? Examples: Ini file XML file

33. UI Mapping. Trivial case Text instruction: When I click on the “Updates” link Actual code: selenium.click( “link=Updates” );

34. UI Mapping. Specific page Will look into this section Will take this locator When I click on the “Apply Button” on the “Links Page” Will click here: selenium.click(“links_apply_btn”) Explicit Selenium calls Similar elements on different pages

35. UI Mapping. Current page Will read current page title Will find section with matching header Will take this locator When I click on the “Apply Button” element Will click here: selenium.click(“links_apply_btn”) Explicit Selenium calls Similar elements on different pages

36. Different keywords can do the same things Examples: When /click on the “(.*)” link/ When /click on “(.*)” link/ When /click on (.*) link/ Main challenges

37. Resolution: Standards & Naming Conventions!!! Trainings & Review!!! Main challenges

38. After that: Examples: When /click on the “(.*)” link/ #Valid as conforms the rules When /click on “(.*)” link/#Invalid. Violates Rule #1 Main challenges Rule #1: each field, element, page name should have “the” article

39. Main challenges Too many keywords Resolution: organize keywords vocabulary

40. Main challenges Data exchange between steps Resolution: use external hash for data storage “My Folder” field now contains actual path

41. Main challenges Random data generation Resolution: Is necessary? Yes Use explicit value No Is needed? Do not pass a value No Yes Pass alias

42. Questions?
