Testing and Debugging Mindset Questions

Practical approaches to testing code and debugging issues throughout the development lifecycle. Candidates should demonstrate knowledge of writing and organizing unit tests, integration tests, and end to end tests, when to use manual exploratory testing versus automated tests, and how to balance test coverage with delivery speed. For debugging, candidates should explain systematic methods for reproducing issues, isolating root causes using logs and traces, using debugger tools and breakpoints, reasoning about asynchronous and concurrency related bugs, leveraging metrics and telemetry, and communicating fixes and mitigations. Emphasis is on building testable code, thinking about edge cases and failure modes, and integrating testing and debugging into regular development workflows.
