## Testing Guide
175+
176+
### Basic Functionality
177+
1. Enable logging in config.yml
178+
2. Set console_output to true
179+
3. Perform actions and verify console output
180+
4. Check log files in plugins/SmartSpawner/logs/spawner/
181+
182+
### Event Coverage Testing
183+
```
184+
✓ Place spawner → SPAWNER_PLACE
185+
✓ Break spawner → SPAWNER_BREAK
186+
✓ Stack by hand → SPAWNER_STACK_HAND
187+
✓ Open storage GUI → SPAWNER_STORAGE_OPEN
188+
✓ Open stacker GUI → SPAWNER_STACKER_OPEN
189+
✓ Destack via GUI → SPAWNER_DESTACK_GUI
190+
✓ Claim XP → SPAWNER_EXP_CLAIM
191+
✓ Sell items → SPAWNER_SELL_ALL
192+
✓ Execute command → COMMAND_EXECUTE_*
193+
✓ Give spawner → ADMIN_GIVE
194+
✓ Reload config → CONFIG_RELOAD
195+
```
196+
197+
