01
Testing Levels
- Unit tests validate isolated software behavior.
- Driver tests validate hardware interfaces.
- Integration tests validate subsystem interactions.
- Hardware-in-the-loop tests connect real controllers to simulated environments.
- System tests validate complete product behavior.
02
Fault Injection
Fault injection deliberately introduces failures such as missing communication, corrupted data, sensor errors, timing disturbances, or power interruptions to determine whether the system responds safely and predictably.
03
Environmental Validation
- Temperature.
- Humidity.
- Vibration.
- Shock.
- Electrical noise.
- Power variation.
- Long-duration operation.
