## Testing Instructions
### Manual Testing
1. **Start Backend:**
```bash
cd ../BACKEND
dotnet run
```
2. **Start Frontend:**
```bash
flutter run -d macos # or chrome, ios, etc.
```
3. **Navigate to Agents:**
- Click "Agents" in sidebar
- Should see empty state with "No Agents Yet"
4. **Test Empty State:**
- Verify empty state icon displays
- Verify "Create Your First Agent" button shows
- Click button → should show "coming soon" snackbar
5. **Test Navigation:**
- Click other sidebar items
- Come back to Agents
- Verify page state persists
### Integration Testing (Once Backend Has List Endpoint)
```dart
// Future test scenarios
- Load agents list
- Display agent cards
- Click agent card → show details
- Click menu → show options
- Create agent → refresh list
- Delete agent → remove from list
```
---
## API Integration Status

| Create Agent | ✅ | ✅ | Ready to integrate |
| Get Agent | ✅ | ✅ | Ready to integrate |
| Update Agent | ✅ | ⏳ | UI pending |
| Delete Agent | ✅ | ⏳ | UI pending |
