architect-bot 1cc81979a4 Merge architect's per-file test detail into the checkpoint doc fix
Architect independently reclaimed this task after my fix landed and
rewrote the same doc with more precise per-file test descriptions and a
more specific gap list -- genuinely better in places (caught real detail
I'd summarized loosely) but its own investigation also introduced one
factual error (claimed 18 tests in test_auth_age_gate.py; verified via
pytest --collect-only, it's 17) and dropped two things worth keeping:
the exact commit hash for reproducibility, and the Client export section
(it never looked at the export step).

Merged: kept the architect's richer per-file coverage descriptions and
gap analysis, restored the verified counts/commit hash/export section/
--quit gotcha from my original.

# Test Inventory
What automated coverage actually exists, what it actually verifies, and what
doesn't have coverage yet. Keep this current as tests are added — it's the
thing a Package Checkpoint review (see `docs/testing/README.md`) reads first
to know what "run the tests" actually checked.
Run everything below in one shot with `scripts/run_checkpoint_tests.py`.
Last verified against `main`: 2026-08-20 (commit `927f9bd`) — full PC1
checkpoint run, fresh clone, migrations + pytest + all 4 Godot smoke tests +
both platform exports, all clean.
## Backend — `backend/tests/` (pytest)
Run: `cd backend && python -m pytest -v` (needs `DATABASE_URL` pointed at a
reachable Postgres — see the runner script).
**Current total: 68 tests, all passing on a clean `main` checkout.**
| File | Tests | What it covers |
|---|---|---|
| `test_auth_age_gate.py` | 17 | `calculate_age()` date-math correctness (exact boundary, leap years, birthday-not-yet-this-year) + `RegisterRequest` date-of-birth validation (parametrized valid/invalid date rejection). Backs the 18+ registration gate (PR #23). |
| `test_gltf_metadata.py` | 21 | glTF/GLB binary + JSON parsing: magic-byte detection, chunk-padding handling, mesh/animation/texture-reference metadata extraction, malformed-input rejection. Backs the asset-import pipeline (PR #27). |
| `test_auth_endpoints.py` | 11 | **Integration tests** for `POST /api/auth/register` and `POST /api/auth/login` against the real FastAPI app + real Postgres. Covers: successful register (201), duplicate username (409), duplicate email (409), underage rejection (400), invalid date format (422), exact-18 registration, successful login with correct credentials (200), wrong password (401), nonexistent user (401), form-encoded login (OAuth2), and JWT validity of returned tokens. |
| `test_refresh_endpoint.py` | 8 | **Integration tests** for `POST /api/auth/refresh`. Covers: successful refresh (200, new access token, same refresh token returned), refresh produces different access tokens on repeated calls, invalid refresh token (401), empty body (422), missing field (422), refresh token from login also works, returned access token is valid JWT decodable with public key, `access_token_expires_minutes` in response. |
| `test_refresh_token_jti.py` | 6 | Unit tests for refresh token uniqueness (jti claim) and model column length. Covers: two calls with same sub produce different tokens (jti uniqueness), jti is valid UUID, rapid repeated calls all produce unique jtis, jti survives decode, `RefreshToken.token` column is `String(512)`, column type is `String`. |
| `test_auth_expired_token.py` | 5 | **Integration tests** for expired-token rejection across auth endpoints. Covers: expired access JWT rejected by `GET /api/auth/me` (401), garbage access token rejected by `/me` (401), missing bearer token returns 401, expired refresh token (DB `expires_at` in past) rejected by `/refresh` (401), expired refresh JWT (past `exp` claim) rejected before DB lookup (401). |
**What these are, honestly:** a mix of pure unit tests (`test_auth_age_gate.py`,
`test_gltf_metadata.py`, `test_refresh_token_jti.py`) and real integration tests
(`test_auth_endpoints.py`, `test_refresh_endpoint.py`, `test_auth_expired_token.py`)
that hit the FastAPI app against a real Postgres database via `TestClient`.
The integration tests exercise the full stack: Pydantic validation → DB →
JWT → response. The suite is also re-runnable without manual cleanup —
`backend/tests/conftest.py` has a session-scoped autouse fixture that
truncates all app tables once before the suite runs.
**Known coverage gaps** (real gaps, not placeholders — nothing enforces filling
these yet):
- No endpoint tests for `GET /api/worlds`, `GET /api/assets/*`, or any
world/asset CRUD routes — only auth endpoints have integration coverage
(`GET /api/worlds` is covered indirectly via the Godot smoke tests below).
- No tests for the moderation schema/migration beyond "the migration runs."
- No tests for the `GET /api/auth/me` endpoint's response body (only its
auth-header validation is covered via expired-token tests).
- No tests for session management (create/validate/revoke sessions).
## Godot client — `scripts/smoke_test_*.gd`
**4 smoke tests merged into `main`.** Each needs a live backend —
`AGP_API_BASE_URL` env var, falling back to the
`application/agp/api_base_url` project setting (default
`http://127.0.0.1:8000`) if unset.
| File | What it covers |
|---|---|
| `smoke_test_api.gd` | Exercises `ApiClient.health_check()` against a live backend. Verifies the real HTTP request path (`HTTPRequest` node lifecycle, JSON parse, result-dictionary contract). Exits 1 on failure. |
| `smoke_test_auth.gd` | Tests the full auth flow via `ApiClient` autoload: register unique user (201), duplicate username (409), under-18 registration (400), correct login (200), wrong password (401), nonexistent user (401). |
| `smoke_test_e2e.gd` | End-to-end flow: health check → register → login → worlds list. Verifies the full request chain with a fresh user, including token storage and `get_worlds()` with auth header. |
| `smoke_test_world_list.gd` | Instantiates `world_list.tscn` as a real scene, adds to tree (catches `@onready` node-path bugs), waits for `_refresh_worlds()` to complete, confirms the screen reaches a real end state (world cards, empty-list message, or error label — not stuck loading). |
Run (once, to build the class cache): `godot --headless --path . --import`,
then for each smoke test: `godot --headless --path . --script
res://scripts/smoke_test_<name>.gd` — **no `--quit`**, it kills these before
their awaited HTTP calls finish.
**Known gaps:**
- No smoke tests for the main menu scene (`main_menu.tscn`).
- No smoke tests for chunk loading/streaming (`chunk.gd`, `chunk_scene.gd`).
- No smoke tests for dynamic/static object nodes.
- All smoke tests require a live backend; no offline/unit smoke tests exist.
- `smoke_test_world_list.gd` is the only one that exercises a real `.tscn`
scene instantiation — others only test the `ApiClient` autoload.
- `get_me()` (`GET /auth/me`) is implemented in `scripts/api_client.gd` but
has no smoke coverage yet.
## Client export
`scripts/build.sh` produces real Linux (`agp-game.x86_64`) and Windows
(`agp-game.exe`) binaries via `--export-release`. Verified 2026-08-20: both
exports complete clean from a fresh checkout and produce valid binaries
(confirmed via `file` — real ELF64/PE32+, not empty or truncated). Neither
export is exercised by an automated GUI test (headless Godot can't drive a
window) — actually launching and clicking through the exported binary is a
manual step, see `docs/checkpoints/PC1.md` for playtest instructions.
## What "full coverage" should eventually mean here
Not defined precisely yet — the honest target as of 2026-08-20 is
"integration tests for every endpoint + smoke tests for every major scene."
As real integration/endpoint tests get added, update the tables above
rather than letting this doc drift stale; a wrong inventory is worse than
no inventory.
