   When evaluating design patterns for a test automation framework, what is a key trade-off to consider when choosing between the Page Object Model and directly interacting with UI elements in test scripts?

   • APage Object Model is always faster to execute, while direct interaction is slower.
   • BPage Object Model increases initial development effort but improves maintainability, while direct interaction is faster to write but harder to maintain.
   • CDirect interaction is more reusable across tests, while Page Object Model is less reusable.
   • DPage Object Model requires no additional code, while direct interaction requires extensive setup.

   A test automation team is designing a framework for a microservices-based application. Each microservice has its own API, and the team wants to create a unified test interface that abstracts the complexity of interacting with multiple services. They also want to ensure that the framework can be extended to support new services without modifying existing test code. Which design pattern should they use?

   • AFacade Pattern
   • BSingleton Pattern
   • CFactory Pattern
   • DStrategy Pattern

   A test automation framework uses a Page Object Model, but the team is struggling with maintaining page objects for a complex application that has many similar pages with slight variations. They want to reduce duplication while keeping the flexibility to override specific behaviors. Which pattern should they consider?

   • AFacade Pattern
   • BSingleton Pattern
   • CTemplate Method Pattern
   • DFactory Pattern
