What is Defect Clustering?

Defect clustering is a general testing principle that suggests that a small number of modules or components in a software system tend to contain a large number of defects. This means that a programmer working on complex code should be aware that certain areas of the code are more likely to have defects than others. By understanding this principle, the programmer can focus their testing efforts on these areas and allocate more time and resources to ensure that these defect-prone components are thoroughly tested and debugged.
