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. Quality Gates intermediate

    Which automated quality gates are worth blocking a release on, and which are ceremony?

  2. Security Testing in the Pipeline intermediate

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

  3. Security Testing in the Pipeline intermediate

    Which security checks belong in the pipeline, and what makes them useful rather than noise?

  4. 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?

  5. Service Virtualisation intermediate

    When should external dependencies be virtualised in testing, and what must the virtual service reproduce?

  6. Service Virtualisation intermediate

    You virtualised a mainframe dependency for testing. Six months later a production integration fails that all tests passed. What happened?

  7. Synthetic Data intermediate Multiple choice

    A payments company must build a test dataset for its fraud-scoring service. Production holds 400M transactions with about 0.2% labelled fraudulent; legal will not permit production data in test environments. The team needs the dataset to exercise the model's decision boundary and the pipeline's handling of awkward records. Which approach fits the requirement as stated?

    When is synthetic data sufficient and when does it mislead?

  9. Test Architecture Strategy intermediate

    What should a test strategy specify, and what makes strategies fail in practice?

    2 min answer test-strategyownershiplayersrisk
  10. Test Data Management intermediate

    What are the test-data options, what must be true regardless, and which combination actually finds the bugs that reach production?

  11. Test Pyramid Shapes intermediate

    A team is told its test suite should be a pyramid. When is that shape wrong?

  12. Test Pyramid Shapes intermediate

    A team's test distribution is an inverted pyramid — many end-to-end tests, few unit tests. What does that cost, and what causes it?
