EmbeddedKafkaStreams

trait EmbeddedKafkaStreams extends EmbeddedKafka with TestStreamsConfig

Helper trait for testing Kafka Streams. It creates an embedded Kafka Instance for each test case. Use runStreams to execute your streams.

  30. def runStreams(topicsToCreate: Seq[String], topology: Topology, extraConfig: Map[String, AnyRef] = Map.empty)(block: ⇒ Any)(implicit config: EmbeddedKafkaConfig): Any

    Execute Kafka streams and pass a block of code that can operate while the streams are active.

    Execute Kafka streams and pass a block of code that can operate while the streams are active. The code block can be used for publishing and consuming messages in Kafka. The block gets a pre-initialized kafka consumer that can be used implicitly for util methods such as consumeLazily(String).

    e.g.

    runStreams(Seq("inputTopic", "outputTopic", topology) {
 // here you can publish and consume messages and make assertions
 publishToKafka(in, Seq("one-string", "another-string"))
 consumeFirstStringMessageFrom(in) should be ("one-string")
}
    topicsToCreate

    the topics that should be created in Kafka before launching the streams.

    topology

    the streams topology that will be used to instantiate the streams with a default configuration (all state directories are different and in temp folders)

    extraConfig

    additional KafkaStreams configuration (overwrite existing keys in default config)

    block

    the code block that will executed while the streams are active. Once the block has been executed the streams will be closed.

    Create a test stream config for a given stream.

    Create a test stream config for a given stream.

    streamName

    the name of the stream. It will be used as the Application ID

    extraConfig

    any additional configuration. If the keys are already defined in the default they will be overwritten with this

    kafkaConfig

    the Kafka test configuration

    returns

    the Streams configuration
