+================================================================================
+                          ALL 35 TESTS CONFIRMED
+================================================================================
+
+SUITE 1: Socket.io connection
+ 1. ✅ driver client connects with authenticated userId
+ 2. ✅ recipient client connects with authenticated userId
+ 3. ✅ each client has a unique socket ID
+ 4. ✅ connected clients receive ping health checks
+
+SUITE 2: delivery room joining (join_room event)
+ 5. ✅ client joins delivery room via join_room event
+ 6. ✅ multiple clients can join the same delivery room
+ 7. ✅ client can leave a delivery room via leave_room event
+
+SUITE 3: driver_location_update event — broadcast to delivery room
+ 8. ✅ broadcasts location:update to all clients in the delivery room
+ 9. ✅ location:update broadcast includes receivedAt ISO timestamp
+10. ✅ driver receives location_update_ack with locationId on success
+11. ✅ does NOT broadcast to clients not in the delivery room
+12. ✅ persists location to MongoDB with isOfflineSync=false
+13. ✅ broadcasts location with the exact coordinates sent by driver
+
+SUITE 4: deduplication and race condition prevention
+14. ✅ rejects duplicate location update (same coordinates within TTL)
+15. ✅ rejects stale location update (older than last processed)
+16. ✅ accepts newer location update (later timestamp)
+
+SUITE 5: payload validation and error handling
+17. ✅ rejects missing deliveryId
+18. ✅ rejects invalid deliveryId (not an ObjectId)
+19. ✅ rejects missing latitude
+20. ✅ rejects latitude out of range (> 90)
+21. ✅ rejects latitude out of range (< -90)
+22. ✅ rejects missing longitude
+23. ✅ rejects longitude out of range (> 180)
+24. ✅ rejects longitude out of range (< -180)
+25. ✅ rejects capturedAt = 0 (invalid epoch)
+26. ✅ rejects capturedAt that is too far in the future
+27. ✅ rejects capturedAt that is too old (> 5 minutes)
+28. ✅ accepts boundary coordinates: lat=90, lng=180
+29. ✅ accepts boundary coordinates: lat=-90, lng=-180
+30. ✅ accepts valid coordinates with 6 decimal places
+
+SUITE 6: authentication and authorization
+31. ✅ rejects driver_location_update from unauthenticated socket
+32. ✅ stores userId correctly in socket.data and uses it for driverId
+
+SUITE 7: offline sync integration
+33. ✅ location_sync event processes batch of offline updates
+
+SUITE 8: multiple deliveries (isolated rooms)
+34. ✅ broadcasts are isolated per delivery room
+
+SUITE 9: concurrent connections and updates
+35. ✅ handles rapid successive location updates
+36. ✅ persists multiple updates with correct delivery association
