The document discusses various design patterns in test automation, emphasizing the importance of maintainability, clarity, and reliability in test logic and structure. It categorizes patterns into structural, data, technical, and business involvement patterns, each aimed at improving test automation efficiency. Key patterns include Page Object, Fluent API, and Behavior Driven Development, highlighting their roles in managing test complexity and supporting clear object-oriented test structures.

- 5. Design pattern? What is it?
- 7. Main driver is *ity Test Logic Application Driver Test Data Reliability Clarity Flexibility Maintainability Stability
- 8. Structural Patterns Structure test code better to improve maintainability, avoid duplicates and separate concepts, so it becomes easier for test engineer to understand, change and support tests.

- 10. Page structure
- 12. #2. Fluent/Chain of invocations
- 14. #4. Page Element/Composite List of Items Link Menu Panel Checkbox
- 17. #6. Strategy • Validation • Navigation • Calculation • Execution
- 18. Data Patterns Separate data management from test logic and reduce amount of data related boilerplate code in tests, making logic more clear and maintainable for test engineers.
- 19. #7. Value Object
- 20. #8. Builder
- 23. #11. Object Pool/Flyweight • DB instance • Browser • Pages • Heavy domain objects
- 25. Entity Driven Data Provider
- 26. Technical Patterns Keep technical aspects separately from test logic if some additional level of control or low level data is needed, reducing tests complexity and improving test code maintainability.

- 28. #14. Proxy
- 29. Use HTTP proxy for tests • Blacklist external resources (Facebook, Twitter, Ads, etc.) • Cache images and other nonfunctional resources • Collect HTTP traffic for analysis (404, redirects, loading time, etc.) • Speedup page loading
- 30. Business Involvement Patterns Try to bring business people and requirements as close as possible to test automation, making it more valuable and helpful for the whole product team.
- 31. #15. Keyword Driven Testing
- 34. #17. Steps
- 35. WebDriver or Pages inside
- 36. Steps is a key for success Acceptance tests Page Objects
- 37. Steps in different formats = Testing scenario WebDriver test
