phase: 07.4-security-token-fingerprinting-token-binding-inserted
plan: "01"
subsystem: testing
tags: [jwt, fgp, token-binding, token-fingerprinting, pytest, xfail, wave-0]
# Dependency graph
requires:
- phase: 07.3-security-es256-algorithm-upgrade-inserted
provides: ES256 JWT signing; conftest _patch_es256_test_keys autouse fixture
- phase: 07.2-security-jti-claim-redis-access-token-revocation-inserted
provides: FakeRedis; make_test_app/auth_client/_create_user harness pattern
provides:
- Wave 0 xfail stubs for FGP-01..FGP-04 in backend/tests/test_auth_fgp.py
- Test harness scaffold ready for Wave 1 (Plan 07.4-02) implementation
affects:
- 07.4-02 (Wave 1 implementation will promote these stubs to real assertions)
# Tech tracking
tech-stack:
added: []
patterns:
- "xfail(strict=False) Wave 0 stub convention: single-line body `pytest.xfail('not implemented yet')`"
- "FGP test harness copies make_test_app/auth_client/_create_user from test_auth_deps.py"
key-files:
created:
- backend/tests/test_auth_fgp.py
modified: []
key-decisions:
- "Wave 0 xfail stubs carry no assertion logic — body is only pytest.xfail(); implementation deferred to Wave 1"
- "Harness copied verbatim from test_auth_deps.py (make_test_app, auth_client, _create_user) — no /test/admin route needed"
patterns-established:
- "FGP tests use the same FakeRedis-backed make_test_app pattern established in Phase 7.2"

- FGP-CONCERN

# Phase 07.4 Plan 01: Wave 0 xfail Stubs for Token Fingerprinting (FGP-01..04) Summary
**4 xfail test stubs covering JWT token fingerprint (fgp) behaviours added to `backend/tests/test_auth_fgp.py` using the Phase 7.2/7.3 xfail(strict=False) Wave 0 convention**
## Performance
- **Duration:** ~8 min
- **Started:** 2026-06-06T17:50:00Z
- **Completed:** 2026-06-06T17:58:00Z
- **Tasks:** 1
- **Files modified:** 1
## Accomplishments
- Created `backend/tests/test_auth_fgp.py` with 4 xfail(strict=False) stubs following the Phase 7.2/7.3 Wave 0 convention
- All 4 stubs report XFAIL in `pytest tests/test_auth_fgp.py -v` — zero failures, zero errors
- Full test suite still runs with 1 pre-existing failure only (test_extract_docx ModuleNotFoundError — unrelated to this plan)
- No production source files modified
## Task Commits
1. **Task 1: Create test_auth_fgp.py with 4 xfail stubs (FGP-01..FGP-04)** - `7833edb` (test)
## Files Created/Modified
- `backend/tests/test_auth_fgp.py` — Wave 0 xfail scaffold: make_test_app harness + 4 FGP stubs (FGP-01..04)
## Decisions Made
- Stub body is only `pytest.xfail("not implemented yet")` — no assertion logic; Wave 1 will replace with real assertions
- Copied make_test_app/auth_client/_create_user verbatim from test_auth_deps.py as the plan specified; no /test/admin route added (not needed for FGP tests)
- Did not include `import base64`, `import time`, `import jwt as _jwt`, or `from config import settings` in the stub file — these imports are needed by the implementation stubs in Wave 1, not the xfail-only Wave 0 stubs
## Deviations from Plan
None - plan executed exactly as written.
## Issues Encountered
None.
## Known Stubs
All 4 test functions are intentional xfail stubs. They will be promoted to full assertions in Plan 07.4-02 (Wave 1) when `_compute_fgp`, `create_access_token` signature extension, and the fgp validation block in `get_current_user` are implemented.
## Threat Flags
None — Wave 0 creates test-only stubs with no new security surface.
## Self-Check: PASSED
- `backend/tests/test_auth_fgp.py` exists and contains 4 test functions
- `7833edb` commit found in git log
- `pytest tests/test_auth_fgp.py -v` reports 4 XFAIL, 0 FAILED, 0 ERROR
## Next Phase Readiness
- Wave 0 scaffold complete; Plan 07.4-02 (Wave 1) can now implement `_compute_fgp` in `services/auth.py`, extend `create_access_token`, add fgp validation in `deps/auth.py`, update login/refresh callers in `api/auth.py`, and promote these 4 stubs to real assertions
