def runStreams(topicsToCreate: Seq[String], builder: TopologyBuilder)(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", streamBuilder) {
 // 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.
builder
the streams builder that will be used to instantiate the streams with a default configuration (all state directories are different and in temp folders)
block
the code block that will executed while the streams are active. Once the block has been executed the streams will be closed.

def runStreamsWithStringConsumer(topicsToCreate: Seq[String], builder: TopologyBuilder)(block: (KafkaConsumer[String, String]) ⇒ Any)(implicit config: EmbeddedKafkaConfig): Any

Run Kafka Streams while offering a String-based consumer for easy testing of stream output.
Run Kafka Streams while offering a String-based consumer for easy testing of stream output.
topicsToCreate
the topics that should be created. Usually these should be the topics that the Streams-under-test use for inputs and outputs. They need to be created before running the streams and this is automatically taken care of.
builder
the streams builder that contains the stream topology that will be instantiated
block
the block of testing code that will be executed by passing the simple String-based consumer.
returns
the result of the testing code

def streamConfig(streamName: String, extraConfig: Map[String, AnyRef] = Map.empty)(implicit kafkaConfig: EmbeddedKafkaConfig): StreamsConfig

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
