It is important to check the environment of the software that is going to reside in. Thus, testing the external factors such as memory, disk space, CPU bandwidth, wall-clock time, disk bandwidth, network bandwidth, colour palette and video resolution should be done too according the #202206201159 principle. This is to know the expected environmental limitations that are going to imposed on the program.
It is the best if there are means for the program to recover fromthe hardware failure gracefully with nice error messages. If that is not possible for whatever reason, at least try to preserve its state to prevent the loss of work which could in turn affect the usability of the software.
