Work Summary — 2026-08-04 19:14

Task

Broaden test coverage beyond server/ui/charts/*_test.go (which was the only tested package). Final step in the dev-iteration plan.

Context

Surveyed domains/accounts, domains/reports, domains/raw_events, domains/amazon and found the codebase is almost entirely thin Store methods wrapping SQL - there's very little pure logic to unit test in isolation. The real risk lives in the queries themselves (already proved this by finding a live bug: RefreshAccessToken in domains/authentication/auth.go:270 passes the empty named return accessToken instead of the oldAccessToken parameter to getRefreshTokenForAccessToken - token refresh is silently broken. Not fixed here, flagging for a decision - see Follow-ups.).

Asked the user how to test DB-heavy code; they chose a dedicated test database with the explicit ability to point the same suite at the real dev DB when wanted.

Infra changes

• Created inventory_2_test Postgres database (owned by app_client, matching inventory_2's setup). The angel OS-peer-auth Postgres role has CREATEDB; app_client does not, so this had to be created out-of-band, not from app code.
• Found and fixed a real migration bug while doing this: database_migrations/000010_oauth_login_states.up.sql had invalid SQL (NOW() + 10 'minute') that fails on any fresh database - a hard blocker for setting up the test DB, and for anyone else spinning up this project from scratch. Fixed to NOW() + '10 minutes'::interval, matching what the live dev DB actually runs (confirmed via psql \d).
• Found and fixed schema drift: migrating fresh revealed oauth_tokens in the migration files still has a claims JSONB NOT NULL column and a TEXT-typed id_token_custom_claims_updated_at - neither matches the live dev DB (no claims column at all; that column is timestamptz), and no application code reads/writes claims. Someone patched the dev DB by hand at some point without ever committing the migration. Added database_migrations/000030_fix_oauth_tokens_schema_drift.{up,down}.sql to close the gap, then migrate force 30 on the dev DB (schema already matched, just needed the migration bookkeeping to catch up) and a normal migrate up on the new test DB. Verified both DBs now have an identical oauth_tokens shape (column ordering differs cosmetically, doesn't matter - the app scans by column name).
• New internal/testdb package: Pool(t) connects via TEST_DATABASE_URL (skips the test if unset, so go test ./... doesn't hard-require Postgres), Logger() for a discard-output logger, NewUserID(t) for collision-safe fixture IDs, SeedOAuthUser/SeedOAuthSession for tests that need a valid oauth_users/oauth_tokens row. All seed helpers register t.Cleanup in FK-safe order.
• Makefile: added test (migrates the test DB, then go test ./...), test-against-dev-db (same suite, TEST_DATABASE_URL overridden to DATABASE_URL for one run - the "option to run against the real database" the user asked for), and migrate-test-up/down/version.
• .env / .env.example: added TEST_DATABASE_URL.

Test coverage added

• domains/authentication/dev_test.go: DevLogin round-trips through GetAccessTokenClaimsAndExpiration correctly, is safe to call twice for the same user_id (mints a new token each time), and GetAccessTokenClaimsAndExpiration returns ErrNotFound for an unknown token.
• domains/accounts/accounts_test.go: CreateAccount happy path + round-trip through GetAccount; duplicate user_id returns ErrConflict; GetAccount on a missing ID returns ErrNotFound; GetUserAndAccountByAccessToken correctly resolves the user-but-no-account state and the user-with-account state (the same join logic the auth middleware depends on for every request).
• domains/raw_events/events_test.go: Save + LoadEventsForStore round-trip, ordering (newest first), and the empty-store case.

Verification

• make test: all new tests pass against inventory_2_test. make test-against-dev-db: same suite, same results, against the real dev DB - confirmed zero leftover rows afterward (SELECT count(*) FROM oauth_users WHERE user_id LIKE 'test-%' → 0, same for raw_store_events).
• go build ./... and go vet ./... clean except two pre-existing unreachable-code warnings unrelated to this work.
• The only test failures are ExampleBar/ExampleLineChart in server/ui/charts - confirmed pre-existing and unrelated (verified via git stash that they fail identically on the pre-session code; see Incident below). Their hardcoded // Output: expectations are stale relative to the current chart-rendering code (missing padding/border/label styling that's since been added).

Incident during verification (self-caused, recovered cleanly)

Used git stash / git stash pop to check whether the chart test failures were pre-existing, and the pop conflicted on server/ui/charts/test.svg (a file the chart tests overwrite as a side effect of running - it was already dirty before this session even started). Resolved by discarding the working-tree's post-test-run test.svg (disposable scratch content) and re-running git stash pop, which then applied cleanly. Verified afterward with go build ./... and a full git status review that every change from this session (and the prior two) was intact. No work was lost, but noting it: don't reach for git stash casually in a working tree with substantial uncommitted work when a narrower check (e.g. git worktree or just re-reading the file) would do.

Follow-ups / not done here

• RefreshAccessToken bug (domains/authentication/auth.go:270): passes the empty named-return accessToken instead of the oldAccessToken parameter to getRefreshTokenForAccessToken, so token refresh looks up an empty string instead of the real token and will always fail to find a refresh token. This means the "refresh when access token is old enough" path in server/auth/auth.go (AuthenticateHandler) is currently broken for real (non-dev) sessions - users would get bounced to / with a "failed to refresh access token" body once their 48-hour ID token crosses the refresh floor, instead of transparently refreshing. Did not fix it in this pass since it's a production auth-flow behavior change, not a test-coverage change - flagging for an explicit decision. It's a one-line fix (accessToken → oldAccessToken on that call).
• No coverage added for domains/reports or domains/amazon - reports.GetRawShopEvents needs a mock-shop fixture (depends on accts.GetMockShop, which lives in the much larger mocks.go/sync_groups.go surface) and domains/amazon's mock event pipeline is stateful/background-process-shaped, both meaningfully bigger lifts than what fit in this pass.
