What are the differences between POM and other design patterns in Selenium?

POM, or Page Object Model, is a design pattern that enhances test maintenance and reduces code duplication. Unlike other patterns, it encapsulates the page elements and actions in separate classes, making tests more readable and easier to manage.

Can you explain how POM improves test automation?

POM improves test automation by promoting reusability of code. Each page is represented by a class, allowing you to write methods for common actions. This means if a UI changes, you only need to update the page class, not every test that interacts with that page.

What are some other design patterns used in Selenium?

Other design patterns include the Singleton pattern, which ensures a class has only one instance, and the Factory pattern, which creates objects without specifying the exact class. Each has its own advantages depending on the testing requirements.

When should I use POM over other patterns?

Use POM when your project has a complex UI with multiple pages or when you need to maintain a large test suite. It helps in organizing code and makes it easier to manage changes.
