An interface in software development is a contract that defines the methods that a class must implement.

• Interfaces in programming languages like Java, C#, and TypeScript provide a way to achieve abstraction and multiple inheritance.

• Classes implementing an interface must provide concrete implementations for all the methods defined in the interface.

• Interfaces allow for loose coupling between components, making code more

Framework structure refers to the organization of test automation code, including folders, files, libraries, and configurations.

POM stands for Page Object Model. It is a design pattern used in test automation to create reusable and maintainable code.

• POM helps in separating the test scripts from the web elements, making the code more organized and easier to maintain.

• It improves code reusability by creating separate classes for each web page, containing all the elements and actions related to that page.

• POM reduces code duplication and enhances te...read more
