2707 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

36 questions in Testing & Quality Architecture.

  1. Flaky Test Management intermediate

    A suite has persistent flaky tests. Why is tolerating them worse than deleting them, and what policy works?

  2. Flaky Test Management intermediate

    A team's CI suite fails roughly one run in three for reasons unrelated to the change. Everyone reruns until green. How do you recover the situation?

  6. Integration Test Boundaries intermediate

    A team replaces every in-process fake with the real dependency in a container, and defect escape rate falls. What have they bought and when does the bill arrive?

  9. Performance Test Design intermediate Multiple choice

    A test must sustain 2000 requests per second against a service whose p50 is 120 ms, with 1 second of think time per virtual user between requests. Roughly how many virtual users does the generator need and what breaks first?

  10. Quality Gates intermediate

    A 12-year-old service has 4% test coverage and no tests for its core logic. It changes twice a year. Do you apply your quality gates to it?
