C)testing is context dependent
D)defect clustering

Question

Quizplus · Accepted Answer

Defect clustering implies that a small number of modules contain most of the defects detected during pre-release testing or show the most operational failures. This principle is based on the Pareto principle, which states that approximately 80% of problems are found in 20% of the modules. Therefore, focusing more on the complex parts of the software, where defects are more likely to cluster, is an application of the defect clustering principle.
