Page Object Model Pattern for UI Testing

Introduction

Page Object Model (POM) is a design pattern that creates an abstraction layer between test code and UI elements, making tests more maintainable.

Why Page Object Model?

Problems Without POM

• Duplicated locators across tests
• Hard to maintain when UI changes
• Test code tightly coupled to UI

Benefits of POM

• Single source of truth for UI elements
• Easy to update when UI changes
• Reusable page methods
• Improved test readability

Best Practices

1. One page object per page/component
2. Methods return page objects
3. No assertions in page objects
4. Keep locators private

Conclusion

POM is essential for maintainable UI automation.
