Your question is Keeping Code Testable as It Evolves. 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).
How do you ensure your code remains testable and scalable as requirements evolve?
Explain the engineering practices, design decisions, and delivery safeguards you would use over the lifecycle of a changing codebase. Address how you would balance short-term delivery pressure with maintainability, validate behavior through automated testing, and identify when an implementation needs refactoring.
