TC8 Conformance Traceability#

This document provides the single source of truth for tracing OPEN Alliance TC8 test cases from the external specification through the project’s internal requirements to the implementing test functions.

Source Document#

  • Title: OA Automotive Ethernet ECU Test Specification — Layers 3–7

  • Version: v3.0

  • Chapter: 5 — SOME/IP

  • Publisher: OPEN Alliance SIG

Note

OA Spec References use test case identifiers from Chapter 5 of the OA Automotive Ethernet ECU Test Specification v3.0 (October 2019). SOMEIPSRV_* IDs are from §5.1.5 (SOME/IP Server Tests) and SOMEIP_ETS_* IDs are from §5.1.6 (Enhanced Testability Service Tests).

Full Traceability Matrix#

The following table links each OA TC8 specification test case to the project’s internal test ID, component requirement, and implementing Python test function(s). All requirement IDs use the comp_req__tc8_conformance__ prefix (omitted for brevity).

Note

TC8-SDF-028 through TC8-SDF-034 (SOMEIPSRV_OPTIONS_08–14, multicast option fields) require a non-loopback NIC and are skipped on loopback with @pytest.mark.network.

Note

TC8-SDF-037 naming: The test function is named test_format_07_unicast_flag_set but verifies the Unicast Flag (bit 6) of the SD Flags byte, which corresponds to SOMEIPSRV_FORMAT_08 in the OA spec. SOMEIPSRV_FORMAT_07 (Reboot Flag) is a separate requirement covered by TC8-SD-012.

SOMEIPSRV_SD_MESSAGE_08 dual coverage: TC8-SD-001 verifies that an OfferService message is present on multicast at startup (behavioural assertion). TC8-SDM-016 verifies the option_index_2 byte in the serialised entry is zero — a distinct field-level assertion from the same spec requirement.

Note

TC8-SDM-012 (SOMEIPSRV_SD_MESSAGE_19) is expected to FAIL against vsomeip 3.6.1: the stack sends a positive ACK instead of NAck for a SubscribeEventgroup with reserved bits set. See the “Known SOME/IP Stack Limitations” section in TC8 SOME/IP Conformance Testing.

TC8-SDLC-011 (SOMEIP_ETS_101) is implemented as pytest.skip because stopping the DUT’s own OfferService from an external tester requires a dedicated reverse-direction SD client target; the current target does not include that capability.

Note

TC8-MSG-022 (SOMEIPSRV_RPC_08) is expected to FAIL against vsomeip 3.6.1: the stack replies to a REQUEST with non-zero return_code when the spec requires no reply. See the “Known SOME/IP Stack Limitations” section in TC8 SOME/IP Conformance Testing.

TC8-MSG-010 (SOMEIPSRV_BASIC_02) is expected to FAIL against vsomeip 3.6.1: the stack silently drops unknown-service requests rather than responding with E_UNKNOWN_SERVICE.

Note

Some TC8 test IDs are implemented by multiple test functions to separate independent assertions. The 189 IDs above correspond to approximately 215 pytest functions in total.

Note

Three tests are expected to FAIL against vsomeip 3.6.1 due to known stack limitations. See the “Known SOME/IP Stack Limitations” section in TC8 SOME/IP Conformance Testing.

Note

Coverage is reported against the subset of TC8 test cases implemented. For the full OA TC8 v3.0 Chapter 5 scope analysis see TC8 SOME/IP Conformance Testing.

How to Update#

When adding a new TC8 test case:

  1. Read the OA specification Chapter 5 to identify the exact test case section number and title.

  2. Add a row to the appropriate area table above with the OA reference, internal TC8 ID, requirement, and test function.

  3. Ensure the test function calls record_property("FullyVerifies", ...) with the matching comp_req__tc8_conformance__<id>.

  4. Update the Coverage Summary counts.
