   A test automation team is evaluating two frameworks: one that uses a strict Page Object Model and another that allows direct UI interaction in test methods. The team values maintainability and wants to minimize the impact of UI changes. Which framework should they choose?

   • ABoth are equally maintainable
   • BIt depends on the programming language
   • CThe framework with direct UI interaction
   • DThe framework with strict Page Object Model

   A test automation team is building a framework that needs to support multiple test data providers (e.g., Excel, JSON, database) and multiple test execution environments (e.g., local, remote grid). They want to avoid hard-coding these choices in test code. Which combination of patterns would best address this?

   • AFactory Pattern for data providers and Strategy Pattern for execution environments
   • BFacade Pattern for data providers and Singleton for execution environments
   • CTemplate Method Pattern for both
   • DSingleton Pattern for both data providers and execution environments

   A test automation team is deciding between using the Page Object Model (POM) and directly interacting with UI elements in test methods. They value maintainability and want to minimize the impact of UI changes on test code. Which approach should they choose?

   • ADirect interaction in test methods
   • BUse a mix of both, depending on the test
   • CPage Object Model
   • DUse a Singleton for the driver and direct interaction

   A test automation framework uses a single web driver instance shared across all test classes. The team has observed that tests interfere with each other when run in parallel. They want to ensure each test gets its own driver instance without modifying every test class. Which pattern should they implement?

   • AFactory Pattern
   • BFacade Pattern
   • CSingleton Pattern
   • DThreadLocal Singleton
