Most simple way to test Kafka Streaming e.g. Read/Write during HBase/Hadoop BigData store or any other Data Ingestion Pipe Lines.

e.g.

{
    "scenarioName": "Unload - Consume a message from kafka",
    "steps": [
        {
            "name": "load_kafka",
            "url": "kafka-topic:demo-c1",
            "operation": "produce",
            "request": {
                "records":[
                    {
                        "key": "${RANDOM.NUMBER}",
                        "value": "Hello World"
                    }
                ]
            },
            "assertions": {
                "status" : "Ok"
            }
        },
        {
            "name": "onload_kafka",
            "url": "kafka-topic:demo-c1",
            "operation": "consume",
            "request": {
            },
            "assertions": {
                "size" : "$GT.0"
            }
        }
    ]
}
