Adds 215 tests across three tiers using node:test + node:assert/strict
(no new test framework dependencies):
- test/tools/ — middleware and utility tests (token, hash, authenticate,
jsonBody, convertError, validators)
- test/shared/ — DbInterface/BackendDbInterface contract suites reusable
across backends (users, abodes, residents, apikeys, sessions, auth)
- test/backends/sqlite/ — SQLite-private tests (sql builder, WrappedDb,
migrator) + shared suites via SqliteInterface
- test/backends/api/ — ApiInterface unit tests + shared suites via a
live Koa server backed by SQLite
Also fixes four bugs uncovered by the tests:
- ApiInterface: path params leaked into query string (slice(1) fix)
- ApiInterface: calling res.json() on 204 No Content responses
- SqliteInterface.updateResident: missing comma in SET clause
- WrappedBetterSqlite3Db: readonly:undefined rejected by better-sqlite3
