Detect Anti-Patterns and Design Violations

In this Master’s Thesis Project, two Code Smells, four Anti-Patterns and four types of Design Principle violations have been examined. We developed a detection program called the Anti-Pattern Scanner. This scanner has been used in an empirical evaluation where five open-source Java projects have been examined and scanned for these ‘pat-tern ’ problems. The results are that the examined problems generally do occur in software systems. The problems are estimated to be inconvenient to software develop-ment, depending on the strength of their presence. Based on the Anti-Pattern Scanner and the results from this evaluation, suggestions for follow-up studies are offered
