Testing is an important part of developing a reliable multiplayer game in Unity.
A multiplayer project needs to be tested not only for normal gameplay, but also for connection problems, synchronization issues, invalid actions, reconnection, different devices, and different network conditions.
This checklist provides a structured approach to testing Unity multiplayer games, including turn-based board games.

- Conclusion
A multiplayer game can appear to work correctly with one player while still having problems when multiple clients interact with the same game state.
Potential issues include:
- Players receiving different game states
- Incorrect turn ownership
- Lost network messages
- Duplicate actions
- Failed reconnections
- Incorrect player positions
- Lobby synchronization problems
- Matchmaking failures
- Invalid client requests
- Performance problems
Testing should therefore cover both normal gameplay and failure scenarios.
Start with the basic multiplayer flow.
- Client can connect to the server
- Connection status is displayed
- Player receives the correct player ID
- Multiple players can connect
- Player disconnects correctly
- Server detects disconnected players
- Match can start
- Players can perform valid actions
- Game state updates correctly
- Other players receive updates
- Match can finish correctly
Test different connection scenarios.
