test(server): GameServer test harness, golden wire transcript, refactor plan - #5114
Conversation
…or plan Phase 0 of docs/GameServerRefactor.md. No production code changes. - tests/util/GameServerHarness.ts: shared mockLogger/makeMockWs/makeClient/ makeGame/startGame and cid() for schema-valid 8-char ids, replacing 13 per-file copies. - Fixture ids are now schema-valid, so the six tests that mocked the Schemas module to get past GameStartInfoSchema no longer need to. - tests/server/GameServerWire.test.ts: a scripted game whose per-client server frames, lobby view, live stats and archived record are snapshotted. A refactor that leaves the snapshot untouched has not changed the wire. - Wire.ts decode helpers accept the zbin dictionary context so post-start frames can be read. - Several tests assert on the wire (spectate/winner messages, start frame) instead of private state: (game as any) reach-ins ~150 -> 82.

Update the Phase 0 verification claim.
npm test runs the full vitest run suite before vitest run tests/server. With the reported client-test failures, npm test is not green and the server command does not run. Document vitest run tests/server as the server-only check, or record the client-test exception and its cause.

🤖 Claude Code ReviewVerdict: Solid test-infrastructure PR with the right intent (real code paths over ad-hoc mocks/reach-ins), but the new shared harness has three issues worth fixing before other PRs build on top of it — one makes a test assertion vacuous, one bakes a mock-only artifact into the new golden snapshot, and one is a latent id-collision trap. Findings: 1 high, 1 medium, 1 low.
|
- GameServerTribes: restore prestart -> flush -> start ordering in the
empty-pool test; startGame() ran start() before the fetch resolved, so the
assertion could not fail.
- Harness mock ws: close() and a triggered "close" now set readyState to
CLOSED like the real socket, so GameServer.end()'s readyState guard behaves
the same. Re-recorded the golden snapshot: p3's old socket is no longer
closed a second time.
- cid(): a second tag that pads to an already-issued id now throws instead of
silently aliasing ("c1" vs "c10"); makeClient's default ids are left-padded
so counter values never alias.

## Summary Phase 1 of `docs/GameServerRefactor.md` (Phase 0 landed in #5114). **Test-only** — no production code changes. Before the refactor moves these paths into their own modules, they need tests that pin what they do today; none of them had any. - **`tests/server/GameServerJoin.test.ts`** — the prod-only duplicate-session kick (the *old* connection is the one told to go), the three-connections-per-IP cap for public games outside dev (and that it does not apply to private games or in dev), a socket that is already closed when it joins, and an undecodable frame → `invalid_message` kick + ban. - **`tests/server/GameServerRejoin.test.ts`** — socket hand-over (old one closed, seat count unchanged), the pre-start identity update, the verified badge dropped only when the *username* changes, update ignored once started, turn replay from `lastTurn`, and a mid-game drop keeping its reconnect mapping. - **`tests/server/GameServerPhase.test.ts`** — Lobby → Active → Finished transitions, the full-lobby early exit, the 3h maximum, the 60s ping prune, and the `mark_disconnected` intents the turn loop injects every five turns (both directions; never for a spectator). - **`tests/server/GameServerDesync.test.ts`** — `findOutOfSyncClients` tallies (majority, no majority → everyone, even split, unreported turn, single client) and the turn loop's one-time desync notice, `numDesyncedClients()`, and agreed-hash recording. Everything goes through the public API and the wire (decoded frames) — no `(game as any)`. **Suspected bug, pinned as current behaviour rather than fixed** (documented in the plan doc for its own PR): a prod duplicate-session kick calls `kickClient()` on the old connection, which bans the *shared* persistentID — so the surviving session can no longer be looked up (`getClientIdForPersistentId`) or reconnect. ## Test plan - `npx vitest tests/server --run`: 45 files / 438 tests green (was 41 / 403). - Because characterization tests passing first try proves little, each file was checked against a hand mutation of the branch it covers in `GameServer.ts` (5-turn boundary → 6, strict-majority `>` → `>=`, identity update allowed after start, dup-session kick removed). Each mutation failed 1–4 of the new tests; all reverted. - prettier, oxlint, eslint, `tsc --noEmit` clean. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
## Summary Phase 2 of `docs/GameServerRefactor.md` (Phases 0–1: #5114, #5116). First PR in the series that touches production code, and it is a signature change only — no behaviour change (the golden wire snapshot's frames are byte-identical). - **`new GameServer(opts, deps?)`** replaces the 10-positional-argument constructor. `GameServerOptions` is what the game *is* (id, log, createdAt, config, creator, startsAt, publicGameType, matchmakingTeams). `GameServerDeps` is what it reaches *outside* itself for: `archive`, `fetchTribes`, `env`, `turnIntervalMs`, `telemetry`, `telemetryBuildHash`, with `defaultGameServerDeps()` wiring the real modules. `env`/`turnIntervalMs` are thunks so `ServerEnv` is read at use time (existing `vi.spyOn(ServerEnv, "env")` tests keep working). - **`GameManager.createGame`** — the only production caller — passes just telemetry. - **`archive` takes the partial record**; the default does `archive(finalizeGameRecord(record))`. This deviates from the plan doc deliberately: `finalizeGameRecord` calls `ServerEnv.gitCommit()`, which **throws when `GIT_COMMIT` is unset**. Once the module mock was gone, that throw landed inside `handleWinner`'s `catch` and silently dropped the archive in a test — precisely the hidden-dependency trap this phase exists to remove. Keeping the deployment stamp in the default dep means tests receive the record as the game built it and never need a `ServerEnv` spy. - `prestart()` logs a malformed prestart message through the game logger instead of `console.error`. - **Tests:** the harness `makeGame` builds the new shape and defaults `archive`/`fetchTribes` to inert spies (`deps: { archive }` to read the record); all 11 direct-constructor test files rewritten; every `vi.mock` of `Archive`/`CustomTribes` removed (5 → 0). Still open, documented in the plan: `archiveGame` remains spied in `WinnerVoteRetally` and `ArchivePlayerRecord`, which assemble game state by hand rather than joining/starting — they get rewritten with Phase 3's `Consensus` extraction. ## Test plan - `npx vitest tests/server --run`: 45 files / 438 tests green (same count as `main`). - Golden snapshot (`tests/server/__snapshots__/GameServerWire.test.ts.snap`): every frame unchanged; the only diff is the three deployment stamps (`gitCommit`/`subdomain`/`domain`) leaving the `archived` object, since the test now sees the record before `finalizeGameRecord`. - Full `npm test`: 30 failing files / 365 tests, identical to the pre-existing `localStorage` baseline on `main`; 36 more passing than before. - `tsc --noEmit`, prettier, oxlint, eslint clean. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
