A typical implementation follows a sequence of managing the container lifecycle alongside the test suite:
: Use methods like getBootstrapServers() to retrieve the dynamically assigned port and map it to your application's configuration (e.g., spring.kafka.bootstrap-servers ). testcontainers-kafka-example
: Instantiate a KafkaContainer using a specific Docker image, such as those from Confluent or the Apache Kafka Native image for faster startup. A typical implementation follows a sequence of managing
: Add the testcontainers and specific kafka module (e.g., org.testcontainers:kafka ) to your build manager (Maven or Gradle). testcontainers-kafka-example
: Run tests where the application interacts with the real broker. Testcontainers automatically cleans up the container after the tests conclude. The best way to use Testcontainers with Spring Boot
