Episode notes
Integration Testing
- Integration testing involves testing code alongside external systems, like databases or email providers.
- It differs from unit tests, which isolate small code units, by focusing on how components interact.
E-commerce Integration Example
- An e-commerce example highlights integration challenges: an order service and a delivery service interact via EventBridge.
- Testing this event flow is crucial to ensure correct order processing and delivery.
Temporary Queues for Event Testing
- Use temporary queues as subscribers or targets when testing event-driven systems like SNS or EventBridge.
- Poll these queues briefly to check message delivery; this offers reliability, but requires setup and latency management.
