cp-testcontainers extends Testcontainers with ready-to-use modules for every major Confluent Platform component. Spin up Schema Registry, ksqlDB, Kafka Connect, and Control Center from a JUnit test with a few lines of Gradle — no Docker Compose, no manual wiring, no “works on my machine.”

Used by workshops, demos, and anyone who needs a real CP stack inside integration tests.
