Method Detail

beforeAll

public void beforeAll(org.junit.jupiter.api.extension.ExtensionContext context)

Specified by:

beforeAll in interface org.junit.jupiter.api.extension.BeforeAllCallback

close

public void close()

Specified by:

close in interface org.junit.jupiter.api.extension.ExtensionContext.Store.CloseableResource

createKafkaContainer

public static io.strimzi.test.container.StrimziKafkaContainer createKafkaContainer()

configureKafkaContainer

public static <T extends io.strimzi.test.container.StrimziKafkaContainer> T configureKafkaContainer(T container)

startKafkaBroker

public void startKafkaBroker()

restart

public static io.strimzi.test.container.StrimziKafkaContainer restart(io.strimzi.test.container.StrimziKafkaContainer kafka,
                                                                      int gracePeriodInSecond)

We need to restart the broker on the same exposed port. Test Containers makes this unnecessarily complicated, but well, let's go for a hack. See https://github.com/testcontainers/testcontainers-java/issues/256.

Parameters:

kafka - the broker that will be closed

gracePeriodInSecond - number of seconds to wait before restarting

Returns:

the new broker

startKafkaBroker

public static io.strimzi.test.container.StrimziKafkaContainer startKafkaBroker(int port)

stopKafkaBroker

public void stopKafkaBroker()
