What is your methodology for testing and improving the quality of your code?

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."
