// MISSION BRIEF

Your Mission

Integration tests deserve real dependencies, disposable ones. This quiz covers Docker-based test environments and the Testcontainers idioms: dynamic ports, readiness waits, cleanup, and what it costs to fake your database instead.

Scoring: timed quiz; accuracy first, speed bonus for fast clean runs.

// FIRST CONTACT

Battle teaser

Testcontainers' core move is:

  1. AStarting real dependencies (Postgres, Kafka, Redis) as throwaway Docker containers from test code, per run
  2. BMocking Docker so no containers are needed
  3. CA Kubernetes distribution for laptops
  4. DA shared staging environment manager
Answers, scoring, hints, and the full battle stay sealed.
