Overview

Can Robot Framework test Kafka clusters and events?

• In the latest version of Robot Framework (6.0.2), there is no support for Kafka Event Streaming. 

Is there any third-party library that would aid in this?

• ConfluentKafkaLibrary is a Robot Framework library to verify Kafka Event Streaming.
• Robotframework-ConfluentKafkaLibrary

Issues

In the current implementation of ConfluentKafkaLibrary, the consumer module connects to Kafka cluster from the port "9092".

    def __init__(
        self,
        server='127.0.0.1',
        port='9092',
        topics='',
        group_id=None,
        only_value=True,
        **kwargs
    ):

Whereas, CPS's kafka container expose its port from "19092"

  kafka:
    image: confluentinc/cp-kafka:6.2.1
    container_name: kafka
    ports:
      - "19092:19092"

In order to solve this conflict, the current port has been changed to 9092 in docker-compose.yml
