Design patterns are crucial in test automation for structured and reusable UI interaction.They offer benefits like enhanced maintainability, improved readability, reduced code duplication, better structure, and increased robustness.Page Object Model (POM) and Functional Helpers are key design patterns for test automation frameworks.POM organizes UI elements by pages/components for clear organization and high reusability.Functional Helpers use functions for common tasks and are more flexible.Choosing between POM and Functional Helpers depends on factors like project scale, team experience, UI complexity, and long-term maintenance.For the article series, POM was chosen for better scalability and popularity.Implementing POM involves creating a logical folder structure and page object files for different pages.Page object classes encapsulate UI elements and actions for specific pages, enhancing maintainability.The article provides a detailed example of implementing page object classes for the Article Page.
