Page Object Model is a design pattern used in test automation to organize and maintain automated test code more efficiently. In this approach, each page of an application is represented by a separate class called a page object. The page object contains the elements of that page, such as buttons, text fields, links, and the methods that interact with those elements. Instead of writing all the automation steps directly in the test scripts, the interactions with the user interface are placed inside these page classes. The main idea behind page object model is to separate the test logic from the page structure and UI interactions. The test scripts focus on the flow of the test case, while the page objects handle how the test interacts with the application’s interface. For example, if a login page has a username field, password field and login button, the page object for the login page would store the locators for those elements and provide methods such as entering a username, entering a password and clicking the login button.
When a test needs to perform an action on that page, it simply calls the method from the page object rather than directly locating and interacting with the element. This makes the test code cleaner, easier to read and more reusable. If the UI changes such as a buttons locator being modified, the update is made only in the page object class instead of in every test case that uses that element.
Page object model improves maintainability, reusability and scalability of automation frameworks. It helps reduce code duplication because the same page methods can be reused across many test cases. It also makes collaboration easier. because testers can clearly see the separation between test scenarios and page-level interactions. Overall, page object model is widely used in automation frameworks, especially with tools like Selenium, because it creates a structured way to manage web elements and actions, leading to more stable and maintainable automated tests.
