What are the differences between Page Object Model and other design patterns?

The Page Object Model (POM) is a design pattern that enhances test maintenance and reduces code duplication. It encapsulates the page structure and behavior in a class, making tests more readable and easier to manage. Other patterns, like the Screenplay Pattern or the Model-View-Controller (MVC), have different focuses and structures.

Can you explain how the Screenplay Pattern differs from POM?

Sure! The Screenplay Pattern emphasizes the roles of actors and their interactions with the system, focusing on user behavior rather than the structure of the UI. In contrast, POM is more about organizing the code related to the UI elements and their actions.

Which pattern is better for large projects?

It depends on the project's needs. POM is great for UI-heavy applications, while the Screenplay Pattern can be more flexible for complex user interactions. It's often beneficial to combine elements of both.

Are there any drawbacks to using Page Object Model?

Yes, while POM improves maintainability, it can lead to over-abstraction if not managed properly. This can make tests harder to understand if the page objects become too complex.
