Tests for WebSocket handlers and connection management.
|
|
|
|
## What's Tested (Unit Tests)
|
|
|
|
- ConnectionManager class:
|
|
- connect(): accepts WebSocket, stores in active_connections
|
|
- disconnect(): removes WebSocket, auto-pauses when last client leaves
|
|
- broadcast(): sends JSON to all connections, handles errors gracefully
|
|
|
|
- WebSocket endpoint /ws:
|
|
- Connection acceptance
|
|
- LLM config required message on connect (when llm_check_failed=True)
|
|
- Ping/pong message handling
|
|
- Disconnect handling (via TestClient context manager)
|
|
|
|
- Control API endpoints:
|
|
- POST /api/control/pause
|
|
- POST /api/control/resume
|
|
- POST /api/control/reset
|
|
|
|
- State/Map API:
|
|
- GET /api/state (error handling, data serialization)
|
|
- GET /api/map (error handling, data serialization)
|
|
|
|
- Event serialization:
|
|
- serialize_events_for_client() function
|
|
|
|
## What's NOT Tested Here (Requires Integration Tests)
|
|
|
|
- game_loop():
|
|
- This is a background async task that runs continuously.
|
|
- It calls sim.step() and broadcasts tick updates every second.
|
|
- Testing this requires mocking the entire game simulation.
|
|
- Covered by: Issue #72 (Game initialization integration test)
|
|
|
|
- WebSocket exception path (non-WebSocketDisconnect errors):
|
|
- Line 684-686 in main.py
|
|
- Edge case when WebSocket throws unexpected exception.
|
|
|
|
Uses FastAPI TestClient with WebSocket support.
