This question examines your practical approach to building quality into the development process rather than relying on manual review at the end.
Key Points: • Use test-driven development to catch design and correctness issues early. • Build CI/CD pipelines with automated tests as a gate before merges and deploys. • Layer in code review and static analysis to catch what automated tests miss. • Treat quality as a continuous practice, not a phase before release.
Example: A team might require unit tests written before implementation code, with a CI pipeline that blocks merges on failing tests and runs integration tests automatically before every deployment.
Interview Tip: A concise interview answer is:
"I advocate for test-driven development to build quality in from the start, backed by CI/CD pipelines that run automated tests on every change. That combination catches issues early and lets us deploy updates faster and with more confidence."
