Review Summary
This PR adds comprehensive test coverage for auth flows and 401 responses across all endpoints. The tests correctly verify both happy paths and error conditions.
Critical
None — no security issues or data isolation bugs.
Minor
- TIL formatting issue — one entry was accidentally split across two lines with another entry inserted in the middle. Clean read-through fix.
- Nice catch on the boundary test —
test_expiring_boundaryverifies the<=operator is correct, which prevents off-by-one bugs in expiry queries.
What I verified
✅ All auth tests match the actual fastapi-users behavior (login uses data= form encoding with username field)
✅ 401 tests correctly target unauthenticated access
✅ Household isolation tests still comprehensive
✅ No missing household_id filters in any query
✅ Boundary test aligns with the Batch.expiry_date <= cutoff logic in batches.py:271
Cost: $0.67
| - **Guard `TEST_DATABASE_URL != DATABASE_URL` at import time.** | ||
| - **`filterwarnings` in `pyproject.toml` scopes warning suppression to a specific package** — `"ignore::DeprecationWarning:fastapi_users_db_sqlalchemy"` suppresses only that library's warnings without risking hiding your own. Useful when a dependency emits unavoidable noise on every test run. A per-test TRUNCATE against production is catastrophic. Read both URLs via the settings class and raise `RuntimeError` at module import — fails before any connection is made. | ||

Typo in the TIL entry: The sentence "filterwarnings..." was inserted in the middle of the existing "Guard TEST_DATABASE_URL != DATABASE_URL..." entry, breaking it across lines 100 and 103. The guard entry should be on one line, and the filterwarnings entry should be separate.
Why this matters: This makes the TIL file harder to read — the guard note is split in half with an unrelated note in between.

Good boundary test! This confirms that the <= operator on line 271 of batches.py is correct — batches expiring on the cutoff day should be included. A common off-by-one bug in expiry logic.
This is the kind of test that catches subtle regressions when someone "simplifies" the query later.

Closes the remaining test gaps from the integration suite: auth flow, unauthenticated access, and two coverage holes identified on review.
Decisions worth noting
client, noauthfixture — testing the auth flow with a pre-authenticated state would defeat the purpose.GET /items/{id}isolation added explicitly — the existing isolation tests covered list, update, and delete for items but missed the single-item GET. The other resources don't have a GET-by-ID endpoint so this is items-specific./expiringboundary test checks both sides of the cutoff — the filter isexpiry_date <= today + days; a batch expiring exactly on the cutoff day must be included, one day after must not. Off-by-one bugs live at boundaries.filterwarningsscoped tightly tofastapi_users_db_sqlalchemy— the library emits a SQLModel deprecation warning on every query. Suppressing broadly would hide genuine warnings; the tight scope limits it to that package only.on_after_registeris not tested — verifying that the orphaned user is deleted when household creation fails would require mocking SQLAlchemy internals. The blanket no-mocks rule exists because isolation bugs are the risk here, not exception handling; this edge case doesn't meet the bar.What's next
