Foundations of Software Testing: Fundamental Algorithms and Techniques

Preliminaries

and in a given environment this probability is 0, then the program

is perfectly reliable despite the possible presence of errors. Certainly,

one could define other metrics to assess software reliability. A num-

ber of other product quality metrics, based on defects, are listed in

Table 1.3.

The OO metrics in the table are due to Shyam Chidamber and Chris

F. Kemerer. These metrics measure program or design complexity. These

are of direct relevance to testing in that a product with a complex design

is likely to require more test effort to obtain a given level of defect density

than a product with less complexity.
