You should see the Kafka and MySQL Docker containers start and all tests pass. After the tests finish, the containers stop and are removed automatically.
Summary
Testing with real Kafka and MySQL instances gives you more confidence in the correctness of your code than mocks or embedded alternatives. The Testcontainers library manages the container lifecycle so that your integration tests run against the same services you use in production.
