Goal

Create an automated end-to-end smoke test that validates:

Client loads — webpack builds, game scene renders (no blank screen)
Socket.IO connects — client establishes connection to backend at port 8081
Game server starts — backend process boots without crashing
Basic round trip — client sends a test message, server responds

Implementation

Server-side (gameServer/main.js)

io.on('connection', (socket) => {
  socket.on('smoke-test-ping', () => {
    socket.emit('smoke-test-pong', { status: 'ok', uptime: process.uptime() });
  });
});

Client-side (tests/e2e/smoke.test.js)

Start backend as child process
Wait for port 8081
Connect with socket.io-client
Send ping → verify pong
Clean up

Run: node tests/e2e/smoke.test.js

Dependencies

Blocked by: #1 (jsdom crash — backend must be fixed first)
Blocks: None
