An Empirical Analysis of Defect Prone Design Pattern
Design patterns are problem-solution pairs that provide proven solutions for commonly occurring design problems. They are used to increase maintainability, reusability, comprehensibility and code quality. However, some studies have indicated relationship between design patterns and defects that doubts the claimed benefits of design patterns. In this paper we present an empirical study to evaluate the error proneness of design patterns. We extract the design patterns from open source software and map these patterns to post-release defects. Information on defects is extracted from version control repositories and bug databases. We have applied Mann-Whitney test to find the design patterns that are more error-prone than others.
Keywords: Design Patter, Code Quality, Reusability, Comprehensibility, Error-Prone Modules.
