12.3. Target System
The target system is the entity under test. As robustness relates to input and environmental stresses, the target system definition is a key issue. Typically, a layered model of a system is used to indicate the different entities in the system. The OS is split into a suitably large number of components, as in Figure 12.1, depending on the goals of the study. A model similar to the one in Figure 12.1 allows for defining the input/output interfaces in the system and to isolate the target system under test.

The model chosen should be general enough to make the approach applicable to more than ...
