Real-time order tracking using Server-Sent Events (SSE). Test WebSocket-like patterns for order status updates, shipping notifications, and delivery tracking.
What you will learn
Subscribe to a Server-Sent Events stream and assert the full status transition sequence in order
Handle reconnection via Last-Event-ID without duplicating or missing updates
Test edge cases — stream close mid-delivery, slow streams, out-of-order events — not just the happy path

Testing Tips
•Test SSE reconnection by refreshing while connected
•Open multiple tabs to test event broadcasting
•Use manual controls to test specific status transitions
