TC8 Test Specifications#

This document provides the detailed test specification for each TC8 conformance test case. Each entry describes the purpose, preconditions, test stimuli, expected results, and requirement traceability.

For the full OA specification mapping see TC8 Conformance Traceability. For requirement definitions see TC8 Conformance Test Requirements.

Note

The “OA Spec Reference” field in each test case references the corresponding section from Chapter 6 of the OPEN Alliance TC8 Automotive Ethernet ECU Test Specification v3.0 (Final). See TC8 Conformance Traceability for the full mapping.

Note

Execution model

The host address is TC8_TESTER_IP; the DUT address is TC8_DUT_IP. Both default values are defined in tc8_itf_conftest.py. To run a test:

bazel test --config=qemu-integration //tests/tc8_conformance:test_tc8_<name>

For QNX x86_64 use --config=x86_64-qnx.

Note

Terminology

Throughout this specification, “server” refers to the SOME/IP Service Provider role (the DUT, which offers services and responds to requests), and “client” refers to the SOME/IP Service Consumer role (the external test harness, which discovers services and subscribes to events). This usage mirrors TC8 OA Section 6.1.5 (“Test Cases SOME/IP Server”) and Section 6.1.6 (“Test Cases ETS”) directly.

Note

DUT scope

The OA ETS cases assume the Enhanced Testability Service. The DUT here is someipd offering service 0x1234 with the instances 0x5678 and 0x5680, eventgroups 0x0002, 0x0005 and 0x0006, the cyclic field 0x8001 (500 ms), the multicast event 0x800B and the fields 0x8005 to 0x8007, which have no update cycle and are sent only as initial fields. It has no trigger methods, so OA steps that call one are marked “Not verified”. The OA procedures take the instance ID from the received OfferService. The tests use the configured ID, which is the same.

comp_req__tc8_conformance__sd_ttl_expiry

Test Function:

TestSDSubscribeLifecycleAdvanced::test_ets_095_subscribe_ttl_expires_no_events

Purpose: Verify that when a subscription’s TTL expires without renewal the DUT ceases sending event notifications to that subscriber.

Stimulus: Subscribe to eventgroup 0x0002 with TTL = 3 seconds, wait 5 seconds without renewal, observe events.

Expected Result: No NOTIFICATION messages received after TTL expiry window.

Not verified: the reaction to an explicit TriggerEventUint8 call (the DUT has no trigger method).
