Bootstraps the public-boundary blackbox test harness owned by epic
AZ-262 (E-BBT). Establishes the e2e/ directory tree at the repo root,
fully separated from src/gps_denied_onboard/** and from the in-process
tests/** tree, and commits to the contracts every subsequent test
ticket (AZ-407..AZ-446) builds against.
Tier-1 (workstation Docker):
- docker/docker-compose.test.yml wires SUT + ArduPilot SITL + iNav SITL
+ mock Suite Sat Service + mavproxy listener + e2e-runner onto one
e2e-net bridge with internal: true (enforces RESTRICT-SAT-1 /
NFT-SEC-02 egress isolation at the network layer).
- docker/docker-compose.tier2-bridge.yml override disables the in-
compose SUT so Tier-2 pairs SITLs + mock + runner on an x86 host
while the SUT runs natively on the Jetson under systemd.
Tier-2 (Jetson):
- jetson/run-tier2.sh + tier2.service systemd unit + tegrastats /
jtop parsers feed per-sample telemetry into the evidence bundle.
Runner image (e2e/runner/):
- Dockerfile + requirements.txt install ONLY ground-side libs
(pymavlink, opencv-python>=4.12, numpy/scipy/geopy/pyproj, httpx,
orjson, pydantic, structlog, pytest 8.x). The runner deliberately
does NOT install the SUT package.
- conftest.py implements the AC-9 skip-rule mapping (tier2_only,
chamber_only, vins_mono, deferred_ac) tied to environment.md
parametrize axes.
- reporting/csv_reporter.py is a pytest plugin emitting one row per
test with the exact 11-column schema from environment.md §
Reporting (test_id, test_name, traces_to, fc_adapter, vio_strategy,
tier, started_at_utc, execution_time_ms, result, error_message,
evidence_paths). XFAIL surfaced only when a test carries
@pytest.mark.deferred_ac(verdict="xfail", reason=...).
- reporting/evidence_bundler.py exposes the attach_evidence fixture
that copies per-test artifacts (.tlog, FDR archives, screenshots,
tegrastats / jtop CSVs) into the run bundle and records relative
paths into the reporter's evidence_paths column.
- helpers/{frame_source_replay,imu_replay,sitl_observer,
mavproxy_tlog_reader,fdr_reader}.py declare the public surfaces
(concrete implementations owned by AZ-407 / AZ-408 / AZ-416 /
AZ-417 / AZ-441 per the dependency table); helpers/geo.py ships
today (no downstream task dep) — WGS84 distance / forward-bearing
/ offset via pyproj with NaN rejection.
Mock Suite Sat Service (e2e/fixtures/mock-suite-sat/):
- FastAPI app: POST /tiles (ingest contract from D-PROJ-2 follow-up),
GET /tiles/audit + /mock/audit (per-run read-back), POST
/mock/config (force-status, response delay), POST /mock/reset
(clears audit between tests), GET /mock/health.
Fixture scaffolds (e2e/fixtures/{tile-cache-builder, age-injector,
injectors, cold-boot, secrets, security}/):
- Public surfaces only. Concrete builders land in AZ-407 (static
fixtures), AZ-408 (runtime synthetic injection), AZ-419 (cold-boot
fixture), AZ-439 (CVE-2025-53644 JPEG generator).
Test tree (e2e/tests/{positive,negative,performance,resilience,
security,resource_limit}/):
- Mirror of the test-spec category grouping in
_docs/02_document/tests/*-tests.md.
- tests/positive/test_smoke.py is the AC-1 harness-boot smoke run
inside the e2e-runner image once Docker brings everything up.
Out-of-container unit tests (e2e/_unit_tests/):
- Exercises the harness internals (CSV reporter plugin lifecycle,
conftest skip rules, helper modules, parsers, mock app, compose
YAML structural contract, public-boundary enforcement) without
Docker / SITL. 97 unit tests, all passing.
Build / config:
- pyproject.toml: testpaths extended with e2e/_unit_tests; pythonpath
extended with e2e; fastapi>=0.111,<0.120 added to dev extras for the
mock-app TestClient unit test.
AC coverage:
- AC-1 (Tier-1 boot) → compose YAML test + directory layout
+ smoke test (Docker-bound)
- AC-2 (mock services) → 6 FastAPI TestClient unit tests
- AC-3 (SITLs accept output) → contract present; concrete check
deferred to AZ-416 / AZ-417
- AC-4 (CSV columns) → in-process plugin lifecycle test
emits the exact 11-column schema
- AC-5 (egress isolation) → static config test + runtime probe
in Docker-bound smoke
- AC-6 (Tier-2 contract) → tegrastats + jtop parser unit tests
+ jetson/* layout test; full Tier-2
contract is AZ-444
- AC-7 (fixture reproducibility) → deferred to AZ-407 per task spec
- AC-8 (parametrize matrix) → vins_mono skip-rule cases +
tests/positive/test_smoke
- AC-9 (skip semantics) → 9 conftest skip-rule unit tests
Module layout entry for blackbox_tests was added in 2026-05-16
preparatory commit d7a17a8 so this diff stays focused on the harness
scaffold. AZ-406 advances to In Testing on commit.
