def withRunningKafkaOnFoundPort[T](config: EmbeddedKafkaConfig)(body: (EmbeddedKafkaConfig) ⇒ T): T

Starts a ZooKeeper instance and a Kafka broker, then executes the body passed as a parameter.

Starts a ZooKeeper instance and a Kafka broker, then executes the body passed as a parameter. The actual ZooKeeper and Kafka ports will be detected and inserted into a copied version of the EmbeddedKafkaConfig that gets passed to body. This is useful if you set either or both port to 0, which will listen on an arbitrary available port.

config: the user-defined EmbeddedKafkaConfig
body: the function to execute, given an EmbeddedKafkaConfig with the actual ports Kafka and ZooKeeper are running on
