Page Object Model

Page Object Model (POM) is a design pattern used in automated testing frameworks to define the structure and layout of web pages. It aims to improve the maintainability and readability of test scripts, especially when dealing with complex web applications that undergo frequent changes.

Benefits of Using Page Object Model

POM offers several advantages, including:

• Improved code organization: POM helps structure test scripts logically by grouping related elements and actions together, making it easier to navigate and understand the code.
• Reduced code duplication: By defining page elements once in a central location, POM eliminates the need to redeclare them in multiple test scripts, minimizing code redundancy and improving maintenance.
• Enhanced test stability: POM decouples the test scripts from the underlying HTML structure of the web pages. This makes the tests less susceptible to breakage caused by changes in the page layout or element identifiers.
• Increased test readability: POM improves the readability of test scripts by using descriptive variable names and methods that align with the page structure, making it easier for testers to understand the flow of the tests.

Components of Page Object Model

A typical POM implementation consists of the following components:

• Page classes: These classes represent individual web pages and contain methods for interacting with the elements on those pages.
• Element locators: Each element locator defines how to find a specific element on a page, using techniques such as CSS selectors or XPath.
• Page factory: A factory class that initializes and manages the creation of page objects, ensuring that only one instance of a page object exists for each page.

How to Implement Page Object Model

To implement POM, follow these steps:

1. Create a page class for each web page under test.
2. Define element locators within the page classes to identify the elements on each page.
3. Use the page factory to instantiate and manage the page objects.
4. Write test scripts that interact with the page objects instead of directly manipulating the web page elements.
