2827 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.

  3. Quality Gates intermediate

    Your CI suite fails about one run in four, and roughly 80% of those failures pass on a re-run. Developers now re-run by reflex, including on real failures. JetBrains ships flaky-test detection in TeamCity based on flip rate. Design the gate, and say what you refuse to do.

  4. Testing & Quality Architecture advanced

    A platform's quality is poor despite a large test suite. What does quality architecture address that more tests do not?

  5. Testing & Quality Architecture beginner

    A service has 95% line coverage and 3,000 passing tests. A bug shipped that made every order for one country total to zero. Why did the suite not catch it, and what kind of test would have?

  7. Security Testing in the Pipeline beginner

    A dependency scanner reports a critical vulnerability in a library your application includes. Reading the advisory, the flaw is in a parser your code never calls. Why does the scanner report it anyway, and what should that change about how you triage?

  8. Security Testing in the Pipeline intermediate

    A pipeline runs security scanning and produces hundreds of findings that nobody acts on. What should change?

  11. Service Virtualisation intermediate

    A grocery marketplace in the mould of Instacart integrates with 140 retailer systems for inventory lookup and order injection. A platform engineer proposes building a virtual service for each one so the test suite can run without them. Roughly what does that cost per year to keep faithful and how many of the 140 are actually worth virtualising?

  12. Service Virtualisation advanced

    A platform integrates with hundreds of external providers, and testing against them is slow, unreliable and sometimes impossible. What is the approach?
