Mock my infrastructure! Using Testcontainers for better integration tests.
summary
Demo shows using Testcontainers with Java and Spring Boot to start real Postgres and a custom MinIO container, inject dynamic JDBC URL/credentials, and run disposable integration tests that start in about two seconds. Slow services like Camunda take minutes so the demo uses reusable containers to avoid repeated startup. Tests run fast enough for CI the example project keeps full-suite builds under ~10 minutes and created buckets and DB rows successfully during each run.
