# System Command

System Commands are used to control the device environment, app lifecycle, and system-level behaviors during a test run. **These commands follow a strict, fixed syntax and must be executed exactly as defined**. System Commands operate outside the UI layer and are not influenced by on-screen elements.

They are typically used for:<br>

1. Managing the app lifecycle (open, kill, clear)
2. Simulating device actions (going back to previous screen)
3. Updating device state (GPS/location)
4. Switching between apps
5. Storing or reusing values within a test
