+"""
+Smoke test: two browser-like peers join a lobby with a bot and should receive addPeer messages.
+
+This test is intentionally simple and fast. It connects two websocket clients to the
+server WebSocket endpoint, sets distinct names, joins the same lobby, and asserts
+that each client receives at least one `addPeer` message (indicating the server
+attempted to establish WebRTC peers). The bot runs in a separate container; the
+test only verifies that the server signaled peers to the connected clients.
