Your question is Explain Core OOP Concepts in Testing. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about the core concepts of OOP and how they apply to your current test framework.
Explain encapsulation, abstraction, inheritance, and polymorphism, then relate each concept to how your framework organizes test cases, page objects, drivers, utilities, and test data. Use one concrete example from a framework you have worked with and mention a design trade-off or misuse you would avoid.
Keep the answer focused on object-oriented design in test automation rather than general programming definitions.
