Spring Test Kafka

Write your integration tests of Spring Framework with Kafka.

You can start Apache Kafka in docker (TestContainers) by the using of @EnableKafkaTestContainer annotation in tests:

@ExtendWith(SpringExtension.class)
@SpringBootTest
@EnableKafkaTestContainer
class KafkaTestContainerTest {

    @Autowired
    private KafkaTemplate<String, String> kafkaTemplate;

    @Test
    void testKafkaFunctionality() {
        //some test with kafka
    }
}

You can use this annotation to start Kafka container in tests both with JUnit5 and JUnit4. The implementation doesn’t depend on some test framework, just on the Spring Framework. How to use multiple Kafka containers in the one test case:

@SpringBootTest
@EnableKafkaTestContainer
@EnableKafkaTestContainer(kafkaBootstrapServersTargetProperty = "my.bootstrap.servers")
class MultipleContainerInOneTest {
    //some tests
}

This code start two Kafka containers. First with default spring.kafka.bootstrap-servers property, second with my.bootstrap.servers.
