# Understanding the Page Object Model pattern

he Page Object Model (POM) is a design pattern that creates an object repository for web UI elements. It helps in:

1. **Reducing code duplication**: Common page interactions are defined once.
2. **Improving maintainability**: Changes to the UI only require updates in one place.
3. **Enhancing readability**: Tests focus on business logic rather than element interactions.
4. **Separating concerns**: Page structure is separated from test logic.

Basic structure of a Page Object Model:

```
tests/
├── pages/           # Page objects directory
│   ├── base.page.ts  # Base page with common methods
│   ├── login.page.ts # Login page object
│   └── ...          # Other page objects
└── specs/           # Test specifications
    ├── login.spec.ts
    └── ...
```
