PM2-Orchestrated E2E Test (Gateway Orchestrator)

This document describes how to run a full end-to-end test using the gateway orchestrator (PM2) so that game-api and game-engine run as real processes and communicate over Redis.

Goal

Validate the full process boundary:

gateway orchestrator starts/stops game-api and turn-daemon via PM2
game-api talks to the daemon over Redis streams
daemon publishes realtime events over Redis pub/sub
optional mutation commands flow from API to engine and back

Where to Implement

Use the existing integration test package and add a PM2-backed test.

Test file: tools/integration-tests/test/orchestrator.e2e.test.ts
Test helpers: tools/integration-tests/src/orchestratorHarness.ts
Reuse existing integration setup in docs/integration-tests.md

Core integration points:

Orchestrator entrypoint: app/gateway-api/src/orchestrator/orchestratorServer.ts
PM2 manager: app/gateway-api/src/orchestrator/pm2ProcessManager.ts
Process names: app/gateway-api/src/orchestrator/gatewayOrchestrator.ts:244
Redis stream keys: app/game-api/src/daemon/streamKeys.ts, app/game-engine/src/lifecycle/redisCommandStream.ts
Turn daemon status endpoint: app/game-api/src/router/turnDaemon/index.ts

Prerequisites

PM2 is installed and available on PATH.
pnpm --filter @sammo-ts/game-api build
pnpm --filter @sammo-ts/game-engine build
pnpm --filter @sammo-ts/gateway-api build (to run orchestrator in dist)
Postgres and Redis are running (use a dedicated DB/schema and Redis DB).

Minimum environment variables for the test:

DATABASE_URL or POSTGRES_* (both game-api and game-engine rely on this)
GATEWAY_DB_SCHEMA (gateway profile DB schema)
REDIS_URL
GAME_TOKEN_SECRET
GATEWAY_REDIS_PREFIX (optional but recommended to isolate keys)
GATEWAY_WORKSPACE_ROOT (workspace root with built dist/)
GATEWAY_WORKTREE_ROOT (worktree root for builds; can be temp)
GATEWAY_TRPC_PATH (e.g. /gateway/api/trpc)
GAME_TRPC_PATH (e.g. /che/api/trpc)
GAME_API_EVENTS_PATH (e.g. /che/api/events)

For profile alignment:

PROFILE and SCENARIO for game server processes
TURN_PROFILE_NAME should match ${PROFILE}:${SCENARIO}

Procedure

Reset state
- Truncate the game schema and gateway schema.
- Flush Redis (or use a dedicated Redis DB index).
Seed the game DB
- Use seedProfileDatabase to seed a scenario and create an admin general.
- Use a fixed INTEGRATION_WORLD_SEED to keep deterministic RNG.
Create/Update the gateway profile record
- Upsert a profile with status RUNNING (or PREOPEN) and a known apiPort.
- Ensure profileName is ${profile}:${scenario}.
Start the orchestrator
- Run app/gateway-api/dist/index.js with GATEWAY_ROLE=orchestrator.
- Or instantiate GatewayOrchestrator directly and call start().
- Wait for PM2 to report the processes as online.
Verify API <-> daemon
- Exchange a gateway session carrying superuser, admin, or admin.profiles.manage[:<profile>] for a game access token.
- Call turnDaemon.status with that administrator token and expect a non-null status.
- Send a mutation command that expects a result (e.g., troop.join) and verify commandResult is received.
Verify realtime events
- Trigger a run via turnDaemon.run with the administrator token.
- Subscribe to sammo:${profileName}:realtime:events and wait for turnCompleted.
Cleanup
- Stop orchestrator, then pm2 delete the processes by name: sammo:${profileName}:game-api and sammo:${profileName}:turn-daemon.
- Flush Redis and drop the test schemas.

What to Check

Mandatory checks:

PM2 reports both processes as online.
Authenticated profile administration is required for every turnDaemon.run/pause/resume/status call.
turnDaemon.status responds within the timeout for the administrator token.
A command with commandResult returns a success response.
A turnCompleted realtime event is observed after a run command.

Optional checks:

worldState.lastTurnTime advances after a run.
A mutation command changes DB state (e.g., troop join/exit).

Notes

turnDaemon.run is fire-and-forget; rely on status or realtime events for confirmation.
PM2 is global; use unique profileName per test run to avoid collisions.
Orchestrator starts binaries from dist/ under GATEWAY_WORKSPACE_ROOT. If build artifacts are missing, PM2 will start and immediately exit.

HWE GUI lifecycle

app/gateway-frontend/e2e/hwe-lifecycle.spec.ts verifies the operational browser flow with one administrator and two independent user contexts:

The administrator logs in, selects hwe:2, loads scenario 2 from a fixed commit, requests a reset, and waits for that exact operation to succeed.
The administrator returns to the gateway main page and sees the open HWE action.
Each user logs in with a separate Chromium context, sees the same open HWE row, creates a general, and reaches the HWE main dashboard without an error.

The test uses an ignored secret directory. It reads admin_password, user_a_password, and user_b_password from SAMMO_LIFECYCLE_SECRET_ROOT; passwords must not be passed on the command line. SAMMO_LIFECYCLE_SOURCE_COMMIT must be a full commit SHA.

Build the gateway frontend with the public prefix contract before starting its preview server:

VITE_APP_BASE_PATH=/gateway \
VITE_GATEWAY_API_URL=/gateway/api/trpc \
VITE_GAME_API_URL_TEMPLATE='/{profile}/api/trpc' \
VITE_GAME_WEB_URL_TEMPLATE='/{profile}/' \
pnpm --filter @sammo-ts/gateway-frontend build

Build the HWE frontend with VITE_APP_BASE_PATH=/hwe, VITE_GAME_API_URL=/hwe/api/trpc, and VITE_GAME_SSE_URL=/hwe/api/events. Start the isolated gateway API, orchestrator, both previews, Postgres, and Redis, then run:

SAMMO_LIFECYCLE_SECRET_ROOT=/path/to/ignored/secrets \
SAMMO_LIFECYCLE_SOURCE_COMMIT="$(git rev-parse HEAD)" \
pnpm --filter @sammo-ts/gateway-frontend test:e2e:hwe-lifecycle

The Playwright web server is a local prefix-preserving proxy on port 15140. It mirrors the Caddy route contract while keeping all navigation on one origin. Passing the test means the actual reset/build/seed/PM2 process path and both user creation flows completed; it is not a mocked API test.
