11. Requirement Traceability¶
11.1 Specification to Test Mapping¶
| Specification Section | Requirement Range | Test Suites |
|---|---|---|
| Message Format | feat_req_someip_29-164 | UT-MSG-, CT-MSG-, ST-CONF-* |
| Serialization | feat_req_someip_167-299 | UT-SER-, CT-MSG- |
| Transport Bindings | feat_req_someip_315-449 | CT-UDP-, CT-TCP-, IT-RPC-* |
| RPC Protocol | feat_req_someip_313-443 | CT-RPC-, IT-RPC- |
| Service Discovery | feat_req_someipsd_1-900 | UT-SD-, CT-SD-, IT-SD-* |
| Transport Protocol | feat_req_someiptp_759-820 | UT-TP-, CT-TP-, IT-TP-* |
| Error Handling | feat_req_someip_364-443 | ST-ROB-* |
| Reserved IDs | feat_req_someipids_504-875 | ST-CONF-007 |
11.2 Gap Analysis¶
Current implementation gaps requiring future work: - E2E Protection: Not implemented (feat_req_someip_102-103) - IPv6 Support: Limited (feat_req_someipsd_140-164) - Load Balancing Option: Informational only (feat_req_someipsd_145-175)
