TC8 Conformance Test Requirements

Feature Requirement

The following feature requirement establishes TC8 SOME/IP conformance testing as a formal verification activity for the SOME/IP Gateway’s protocol stack.

TC8 SOME/IP Protocol Conformance		status: valid security: NO safety: QM
tags: tc8, conformance, someip, verification reqtype: Functional satisfies: stkh_req__docgen_enabled__example satisfied by: comp_req__tc8_conformance__sd_offer_format, comp_req__tc8_conformance__sd_cyclic_timing, comp_req__tc8_conformance__sd_find_response, comp_req__tc8_conformance__sd_sub_lifecycle, comp_req__tc8_conformance__sd_phases_timing, comp_req__tc8_conformance__msg_resp_header, comp_req__tc8_conformance__msg_error_codes, comp_req__tc8_conformance__evt_subscription
The SOME/IP Gateway project shall verify protocol conformance of its SOME/IP stack (someipd) against OPEN Alliance TC8 SOME/IP test specifications at the wire protocol level, without requiring application processes. Note: The :satisfies: link targets a placeholder stakeholder requirement. This shall be updated to reference the upstream S-CORE stakeholder requirement for SOME/IP interoperability once it is formally defined.

Component Requirements — Service Discovery

The following component requirements define the high-priority TC8 conformance tests for SOME/IP Service Discovery (SD), aligned with SOME/IP-SD Protocol Specification (AUTOSAR PRS_SOMEIP_SD).

TC8 SD Offer Entry Format Validation		status: valid security: NO safety: QM
tags: tc8, conformance, service_discovery reqtype: Functional satisfies: feat_req__tc8_conformance__conformance
The conformance test suite shall verify that someipd transmits SOME/IP-SD OfferService entries on the configured multicast group with correct service ID, instance ID, major/minor version, and TTL fields upon startup. Note: Traces to SOME/IP-SD specification sections 4.1.2.1 (OfferService entry format) and 4.1.2.3 (Service Entry fields). Covers TC8-SD-001 and TC8-SD-002 from the test strategy.

TC8 SD Cyclic Offer Timing		status: valid security: NO safety: QM
tags: tc8, conformance, service_discovery, timing reqtype: Functional satisfies: feat_req__tc8_conformance__conformance
The conformance test suite shall verify that someipd repeats OfferService entries at the configured cyclic_offer_delay interval (±20% tolerance) during the main phase of Service Discovery. Note: Traces to SOME/IP-SD specification section 4.1.1 (SD Phases — Main Phase, cyclic offer behavior). Covers TC8-SD-003 from the test strategy.
comp_req__tc8_conformance__sd_cyclic_timing		Component Requirement

TC8 SD FindService Response		status: valid security: NO safety: QM
tags: tc8, conformance, service_discovery reqtype: Functional satisfies: feat_req__tc8_conformance__conformance
The conformance test suite shall verify that someipd responds to a SOME/IP-SD FindService entry with a unicast OfferService for a known service, and does not respond for an unknown service. Note: Traces to SOME/IP-SD specification section 4.1.2.2 (FindService entry handling and response behavior). Covers TC8-SD-004 and TC8-SD-005 from the test strategy.
comp_req__tc8_conformance__sd_find_response		Component Requirement

TC8 SD Subscribe Eventgroup Lifecycle		status: valid security: NO safety: QM
tags: tc8, conformance, service_discovery, eventgroup reqtype: Functional satisfies: feat_req__tc8_conformance__conformance
The conformance test suite shall verify that someipd correctly handles the SubscribeEventgroup lifecycle: acknowledge valid subscriptions (SubscribeEventgroupAck), reject unknown eventgroups (SubscribeEventgroupNack with TTL=0), and honor StopSubscribeEventgroup by ceasing notifications. Note: Traces to SOME/IP-SD specification sections 4.1.2.4 (SubscribeEventgroup), 4.1.2.5 (StopSubscribeEventgroup), and 4.1.2.6 (SubscribeEventgroupAck/Nack). Covers TC8-SD-006, TC8-SD-007, and TC8-SD-008 from the test strategy.
comp_req__tc8_conformance__sd_sub_lifecycle		Component Requirement

TC8 SD Initial Delay and Repetitions Phase		status: valid security: NO safety: QM
tags: tc8, conformance, service_discovery, timing reqtype: Functional satisfies: feat_req__tc8_conformance__conformance
The conformance test suite shall verify that someipd observes the three SD phases: initial wait delay within [initial_delay_min, initial_delay_max], repetition of offers repetitions_max times at repetitions_base_delay intervals, and transition to main phase. Note: Traces to SOME/IP-SD specification section 4.1.1 (SD Phases — Initial Wait, Repetition, Main Phase). Covers TC8-SD-009 and TC8-SD-010 from the test strategy.
comp_req__tc8_conformance__sd_phases_timing		Component Requirement

Component Requirements — SOME/IP Message Format

TC8 SOME/IP Response Header Validation		status: valid security: NO safety: QM
tags: tc8, conformance, message_format reqtype: Functional satisfies: feat_req__tc8_conformance__conformance
The conformance test suite shall verify that someipd returns SOME/IP RESPONSE messages with correct protocol version (0x01), message type (0x80), matching session ID, and matching client ID for each received REQUEST. Note: Traces to SOME/IP specification sections 4.1.4 (Protocol Version), 4.1.6 (Message Type), and 4.1.3 (Request ID — Client ID / Session ID). Covers TC8-SOMEIP-MSG-001, TC8-SOMEIP-MSG-002, TC8-SOMEIP-MSG-005, and TC8-SOMEIP-MSG-008 from the test strategy.
comp_req__tc8_conformance__msg_resp_header		Component Requirement

TC8 SOME/IP Error Return Codes		status: valid security: NO safety: QM
tags: tc8, conformance, message_format, error_handling reqtype: Functional satisfies: feat_req__tc8_conformance__conformance
The conformance test suite shall verify that someipd returns the correct SOME/IP return codes for error conditions: E_UNKNOWN_SERVICE (0x02) for requests to non-existent services, E_UNKNOWN_METHOD (0x03) for invalid method IDs, and E_WRONG_INTERFACE_VERSION for interface version mismatches. Note: Traces to SOME/IP specification section 4.1.7 (Return Code) and the return code table (Table 4.14). Covers TC8-SOMEIP-MSG-003, TC8-SOMEIP-MSG-004, and TC8-SOMEIP-MSG-006 from the test strategy.

Component Requirements — Event Notification

TC8 Event Notification Subscription Lifecycle		status: valid security: NO safety: QM
tags: tc8, conformance, events, notification reqtype: Functional satisfies: feat_req__tc8_conformance__conformance
The conformance test suite shall verify that someipd delivers NOTIFICATION messages (message type 0x02) with correct event ID only to endpoints with an active eventgroup subscription, and ceases delivery after StopSubscribeEventgroup. Note: Traces to SOME/IP specification section 5.1 (Events) and SOME/IP-SD section 4.1.2.4 (SubscribeEventgroup triggering notification delivery). Covers TC8-EVT-001 through TC8-EVT-004 and TC8-EVT-006 from the test strategy.
