Worst‐case testing evaluates the software's ability to deal with variation, tolerance stackup and environmental drift in the device's I/O, hardware, and circuits that is short of the total failure situations evaluated during fault injection testing. Worst‐case software testing requires a detailed understanding of the design of the device and its software structure. It is the responsibility of the system engineers and software architects to define the specific requirements, test plan scripts, and acceptance criteria for the device. The plan should be reviewed with the product team and the results reported after the testing. The evaluation procedure may reveal that the system requires addition operating state inputs like temperature sensor inputs to identify the extremes of worst‐case operating conditions.
