A software tester’s work life includes making sure that systems that have been designed to achieve specific results behave exactly as they should. These systems are a combination of different hardware and software which have been configured to perform the desired task. What is Configuration Testing? An Example.

This is a companion paper to the " persistent problem " piece that we looked at earlier this week, going a little deeper into the object pointer representation choices and the mapping of a virtual object space into physical address spaces. Both abstractions must be implemented in a way that is efficient using existing hardware.
