Event-Driven System Testing

Welcome to testing modern architectures! We'll explore event-driven systems, a popular design pattern.

These systems communicate through events, which are notifications of something that has happened. Think of it like a newspaper delivering news to many subscribers.

This approach helps decouple different parts of an application, making them more flexible and scalable.

Just like any system, event-driven architectures need robust performance testing. Why?

• Reliability: Ensure events are delivered and processed without loss.
• Throughput: Verify the system can handle the expected volume of events per second.
• Latency: Measure the time it takes for an event to travel from its origin to its final processing.
• Scalability: Check how the system performs as event load increases.
