Automated testing is a core engineering practice because it reduces regressions, improves release confidence, and supports fast iteration. Interviewers often use this topic to assess whether you understand both the tools and the engineering trade-offs behind them.
Explain your experience with automated testing tools and how you would use them in a real codebase. In your answer, address:
The interviewer expects a practical conceptual explanation rather than a personal story. Focus on testing strategy, common tools, trade-offs, reliability, maintainability, and how strong automated testing improves software quality over time.
