The
system testing procedure tests for errors resulting from unexpected
interactions among sub-systems and system components.
System testing is black-box testing. System testing will often involve load testing and stress testing of the system under development. The testers need to verify that the system handles loads within its specified range while still meeting the specified non-functional requirements. The testers need to verify that the system fails gracefully when pushed beyond its specified maximum load.
The procedure tests for the accurate processing of input by the Command Processing System. The Command Processing System must also send correct signals and information to the other sub-systems based on this input. The Oven Control System must correctly receive signals and information from the Command Processing System and send the appropriate signals to the microwave generator. Likewise, the Output Processing System must also correctly accept signals and information from the Command Processing System and send appropriate signals to the LCD and beeper mechanism. The hardware components must all correctly accept signals from their assigned sub-system.
