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.

The system testing
test plan
creation activity should start as the system requirements and system
specificaton artifacts become
relatively stable and mature.
