From e75c21bca14d7c40ba96fbbc829e43b30e5f586b Mon Sep 17 00:00:00 2001 From: "Jorge C. Santos" Date: Tue, 24 Mar 2026 10:49:55 +0100 Subject: [PATCH 01/64] Add TC8 SOME/IP conformance test suite for someipd Wire-level pytest tests verifying someipd against the OA TC8 ECU Test Specification v3.0 Chapter 5: service discovery (phases, reboot, timing), message format, event notification, field lifecycle, and TCP transport. - someipd --tc8-standalone mode: request/response, field GET/SET, UDP and TCP events; offer_event uses ET_FIELD so vsomeip delivers the cached field value to new subscribers immediately on subscribe (is_field in JSON config is not honoured in programmatic offer_event calls) - vsomeip config templates for SD timing and service/event/field/TCP tests, with JSON Schema validation at lint time - Architecture doc, requirements, test specification and OA spec traceability - Bazel port isolation via the env attribute: each target receives unique SD and service ports enabling medium targets to run in parallel; timing-sensitive and reboot lifecycle targets retain the exclusive tag for serial execution --- .github/workflows/build_and_test_host.yml | 21 + MODULE.bazel | 2 +- docs/architecture/index.rst | 13 + docs/architecture/tc8_conformance_testing.rst | 1197 ++++++ docs/requirements/index.rst | 2 +- docs/tc8_conformance/index.rst | 28 +- docs/tc8_conformance/requirements.rst | 600 ++- docs/tc8_conformance/test_specification.rst | 3278 +++++++++++++++++ docs/tc8_conformance/traceability.rst | 1102 ++++++ src/someipd/BUILD.bazel | 1 + src/someipd/main.cpp | 472 ++- tests/integration/BUILD.bazel | 5 +- tests/tc8_conformance/BUILD.bazel | 256 ++ tests/tc8_conformance/README.md | 190 + tests/tc8_conformance/application/README.md | 51 + .../config/tc8_someipd_config.schema.json | 207 ++ .../config/tc8_someipd_multi.json | 74 + .../config/tc8_someipd_sd.json | 64 + .../config/tc8_someipd_service.json | 88 + tests/tc8_conformance/conftest.py | 257 ++ tests/tc8_conformance/helpers/__init__.py | 13 + tests/tc8_conformance/helpers/constants.py | 51 + .../tc8_conformance/helpers/event_helpers.py | 212 ++ .../tc8_conformance/helpers/field_helpers.py | 147 + .../helpers/message_builder.py | 183 + tests/tc8_conformance/helpers/sd_helpers.py | 141 + tests/tc8_conformance/helpers/sd_malformed.py | 838 +++++ tests/tc8_conformance/helpers/sd_sender.py | 332 ++ .../helpers/someip_assertions.py | 175 + tests/tc8_conformance/helpers/tcp_helpers.py | 187 + tests/tc8_conformance/helpers/timing.py | 80 + tests/tc8_conformance/helpers/udp_helpers.py | 71 + .../test_event_notification.py | 705 ++++ .../tc8_conformance/test_field_conformance.py | 400 ++ tests/tc8_conformance/test_multi_service.py | 327 ++ tests/tc8_conformance/test_sd_client.py | 417 +++ .../test_sd_format_compliance.py | 1529 ++++++++ .../tc8_conformance/test_sd_phases_timing.py | 166 + tests/tc8_conformance/test_sd_reboot.py | 419 +++ tests/tc8_conformance/test_sd_robustness.py | 863 +++++ .../tc8_conformance/test_service_discovery.py | 2189 +++++++++++ .../test_someip_message_format.py | 1560 ++++++++ 42 files changed, 18727 insertions(+), 186 deletions(-) create mode 100644 docs/architecture/tc8_conformance_testing.rst create mode 100644 docs/tc8_conformance/test_specification.rst create mode 100644 docs/tc8_conformance/traceability.rst create mode 100644 tests/tc8_conformance/BUILD.bazel create mode 100644 tests/tc8_conformance/README.md create mode 100644 tests/tc8_conformance/application/README.md create mode 100644 tests/tc8_conformance/config/tc8_someipd_config.schema.json create mode 100644 tests/tc8_conformance/config/tc8_someipd_multi.json create mode 100644 tests/tc8_conformance/config/tc8_someipd_sd.json create mode 100644 tests/tc8_conformance/config/tc8_someipd_service.json create mode 100644 tests/tc8_conformance/conftest.py create mode 100644 tests/tc8_conformance/helpers/__init__.py create mode 100644 tests/tc8_conformance/helpers/constants.py create mode 100644 tests/tc8_conformance/helpers/event_helpers.py create mode 100644 tests/tc8_conformance/helpers/field_helpers.py create mode 100644 tests/tc8_conformance/helpers/message_builder.py create mode 100644 tests/tc8_conformance/helpers/sd_helpers.py create mode 100644 tests/tc8_conformance/helpers/sd_malformed.py create mode 100644 tests/tc8_conformance/helpers/sd_sender.py create mode 100644 tests/tc8_conformance/helpers/someip_assertions.py create mode 100644 tests/tc8_conformance/helpers/tcp_helpers.py create mode 100644 tests/tc8_conformance/helpers/timing.py create mode 100644 tests/tc8_conformance/helpers/udp_helpers.py create mode 100644 tests/tc8_conformance/test_event_notification.py create mode 100644 tests/tc8_conformance/test_field_conformance.py create mode 100644 tests/tc8_conformance/test_multi_service.py create mode 100644 tests/tc8_conformance/test_sd_client.py create mode 100644 tests/tc8_conformance/test_sd_format_compliance.py create mode 100644 tests/tc8_conformance/test_sd_phases_timing.py create mode 100644 tests/tc8_conformance/test_sd_reboot.py create mode 100644 tests/tc8_conformance/test_sd_robustness.py create mode 100644 tests/tc8_conformance/test_service_discovery.py create mode 100644 tests/tc8_conformance/test_someip_message_format.py diff --git a/.github/workflows/build_and_test_host.yml b/.github/workflows/build_and_test_host.yml index 60e65fa43..35a2a8d08 100644 --- a/.github/workflows/build_and_test_host.yml +++ b/.github/workflows/build_and_test_host.yml @@ -51,5 +51,26 @@ jobs: -

The DUT is ``someipd`` in standalone mode. Tests send raw SOME/IP +messages and verify responses against the TC8 specification. + +Standalone Mode +^^^^^^^^^^^^^^^ + +``someipd`` normally waits for ``gatewayd`` to connect via LoLa IPC before +offering services. The ``--tc8-standalone`` flag removes this dependency: +``someipd`` skips the IPC proxy setup and calls ``offer_service()`` directly. + +This keeps protocol conformance tests simple — no process ordering, no +FlatBuffers config, and fewer failure modes. See ``src/someipd/main.cpp``. + +Port Isolation and Parallel Execution +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Each Bazel TC8 target runs in its own OS process and receives unique SOME/IP +port values via the Bazel ``env`` attribute. Three environment variables +control port assignment: + +``TC8_SD_PORT`` + SOME/IP-SD port. Set in both the vsomeip config template (replacing the + ``__TC8_SD_PORT__`` placeholder) and read by the Python SD sender socket + at module import time via ``helpers/constants.py``. The SOME/IP-SD + protocol requires SD messages to originate from the configured SD port; + satisfying this does not require a fixed port — it requires only that + both sides use the *same* port, which is guaranteed because both the + vsomeip config and the Python constants read the same env var. + +``TC8_SVC_PORT`` + DUT UDP (unreliable) service port. Replaces the ``__TC8_SVC_PORT__`` + placeholder in config templates. + +``TC8_SVC_TCP_PORT`` + DUT TCP (reliable) service port. Replaces the ``__TC8_SVC_TCP_PORT__`` + placeholder in config templates. Only set for targets that use reliable + transport (``tc8_message_format``, ``tc8_event_notification``, + ``tc8_field_conformance``). + +All three constants default to the historical static values (30490 / 30509 / +30510) when the environment variables are not set, preserving backward +compatibility for local development runs without Bazel. + +.. rubric:: Port Assignment per Target + +.. list-table:: + :header-rows: 1 + :widths: 30 15 15 20 20 + + * - Target + - TC8_SD_PORT + - TC8_SVC_PORT + - TC8_SVC_TCP_PORT + - exclusive + * - ``tc8_service_discovery`` + - 30490 + - 30500 + - — + - no + * - ``tc8_sd_phases_timing`` + - 30491 + - 30501 + - — + - yes (timing) + * - ``tc8_message_format`` + - 30492 + - 30502 + - 30503 + - no + * - ``tc8_event_notification`` + - 30493 + - 30504 + - 30505 + - no + * - ``tc8_sd_reboot`` + - 30494 + - 30506 + - — + - yes (lifecycle) + * - ``tc8_field_conformance`` + - 30495 + - 30507 + - 30508 + - no + * - ``tc8_sd_format`` + - 30496 + - 30509 + - — + - no + * - ``tc8_sd_robustness`` + - 30497 + - 30510 + - — + - no + * - ``tc8_sd_client`` + - 30498 + - 30511 + - — + - yes (lifecycle) + * - ``tc8_multi_service`` + - 30499 + - 30512 + - 30513 + - no + +The four medium targets (``tc8_service_discovery``, ``tc8_message_format``, +``tc8_event_notification``, ``tc8_field_conformance``) run in parallel.

Each requirement must be traceable upward to a +business goal and downward to a test: + +* **Stakeholder requirements** (``stkh_req``) — *why* something is needed + (business or interoperability goal). +* **Feature requirements** (``feat_req``) — *what* capability is needed. + Each ``feat_req`` links to a ``stkh_req`` via ``:satisfies:``. +* **Component requirements** (``comp_req``) — the *specific, testable + behaviour*. Each ``comp_req`` links to a ``feat_req`` via + ``:satisfies:``, and each test links back via + ``record_property("FullyVerifies", ...)``. + +This creates **bidirectional traceability**: from a stakeholder need down +to the test that proves it is met, and from any test back up to the +business goal. Sphinx-Needs tooling uses these links to generate coverage +matrices and detect gaps. + +How the feature / component split works for TC8 +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +For TC8 conformance, the split is simple: + +* **One feature requirement** + (``feat_req__tc8_conformance__conformance``) covers the overall goal: + "verify ``someipd`` against OA TC8 SOME/IP at the wire level." This + requirement does **not** change when new test areas are added. + +* **Many component requirements** — one per testable protocol aspect + (e.g., SD offer format, cyclic timing, response headers, TCP + transport). Each component requirement: + + - Describes the specific behaviour under test. + - References the relevant AUTOSAR PRS or TC8 specification section. + - Is verified by one or more pytest functions. + +.. note:: **When to extend this document** + + When new TC8 conformance tests are added (e.g., new OA specification + chapters or protocol areas like SOME/IP-TP), update the documents as + follows: + + 1. **The feature requirement stays unchanged** — it already covers + the overall TC8 protocol conformance goal. + 2. **Add new component requirements** to this file for each testable + behaviour. Group them under a new heading (e.g., + "Component Requirements — SOME/IP-TP"). + 3. **Add test case descriptions** in :doc:`test_specification`. + 4. **Add OA-to-internal mapping rows** in :doc:`traceability`. + 5. Each new pytest function must call + ``record_property("FullyVerifies", "")`` to close + the traceability chain. + + A **new feature requirement** is only needed if the scope expands + beyond wire-level protocol conformance — for example, a separate + "TC8 Enhanced Testability" campaign would need its own ``feat_req``. + +Requirement Hierarchy Diagram +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The diagram below shows how the three requirement levels, the test code, +the external OA standard, and the documentation files relate to each other. + +.. uml:: + + @startuml + !theme plain + + scale max 800 width + skinparam packageStyle rectangle + skinparam linetype ortho + skinparam nodesep 50 + skinparam ranksep 50 + + package "S-CORE Requirement Hierarchy" { + rectangle "**Stakeholder Requirement**\n(stkh_req)" as STKH #b1ddf0 { + rectangle "stkh_req~__docgen_enabled~__example\n//High-level interoperability need//" as SReq + } + rectangle "**Feature Requirement**\n(feat_req)" as FEAT #fff2cc { + rectangle "feat_req~__tc8_conformance~__conformance\n//TC8 SOME/IP protocol conformance//" as FReq + } + rectangle "**Component Requirements**\n(comp_req)" as COMP #d5e8d4 { + rectangle "comp_req~__tc8_conformance~__*\n//One per testable protocol behaviour//" as CReq + } + } + + package "Test Implementation" { + collections "**tests/tc8_conformance/*.py**\nPython test functions\n(pytest + raw SOME/IP)" as Tests #f5f5f5 + } + + package "TC8 Conformance Docs" { + file "**test_specification.rst**\nDetailed test cases:\npurpose, stimuli,\nexpected results" as TestSpec #f5f5f5 + file "**traceability.rst**\nOA Spec ID →\nInternal ID →\nRequirement →\nTest Function" as Trace #f5f5f5 + } + + package "External Standard" { + rectangle "**OA TC8 Spec**\nChapter 5 — SOME/IP\nSOMEIPSRV_*, SOMEIP_ETS_*" as OASpec #e0e0e0 + } + + ' --- Relationships --- + + ' Requirement satisfaction hierarchy (vertical within hierarchy) + FReq -up-> SReq : <> + CReq -up-> FReq : <> + + ' Test verification + Tests -up-> CReq : <> + + ' Documentation and Traceability + TestSpec -up-> COMP : <> + Trace -up-> COMP : <> + Trace --> Tests : <> + Trace --> OASpec : <> + + @enduml + +The relationships work as follows: + +1. **Stakeholder → Feature** (``:satisfies:``): + The feature requirement satisfies the stakeholder need for SOME/IP + interoperability. + +2. **Feature → Component** (``:satisfies:``): + Each component requirement defines a specific, testable protocol + behaviour and links up to the single feature requirement. + +3. **Component → Test** (``record_property("FullyVerifies", ...)``): + Each pytest function creates a machine-readable link back to the + component requirement it verifies (emitted in JUnit XML). + +4. **Test → External Standard** (traceability matrix): + The :doc:`traceability` maps each internal test ID to the + corresponding OA TC8 specification test case, closing the chain + from external standard to verified implementation. + +Requirement Areas +^^^^^^^^^^^^^^^^^ + +The component requirements are grouped by TC8 test area: + +.. list-table:: + :widths: 30 20 50 + :header-rows: 1 + + * -
