Tell us about your experience using message brokers in projects.

In projects with test automation and QA, I used message brokers to integrate various components and handle events in distributed systems.

For example, I used RabbitMQ and Apache Kafka for:

• Asynchronous data transfer between microservices.
• Organizing task queues for processing test scenarios.
• Logging and monitoring events in real-time.

Experience shows that message brokers help reduce component coupling, increase scalability, and system resilience. In testing, this allows emulating real interaction scenarios and verifying message processing correctness.

An example of usage: a test script publishes a message to a queue, and the service under test consumes it and performs the corresponding action. This helps verify the correctness of asynchronous event processing.
