Analyzing the Evolution of WSDL Interfaces using Metrics

Recent studies have investigated the use of source code metrics to predict the change- and defect-proneness of source code. While the indicative power of these metrics was validated for several systems, it has not been tested on Service-Oriented Architectures (SOA). In particular, the SOA paradigm prescribes the development of systems through...

The Impact of Antipatterns on the Change-Proneness of Java Systems

We replicated a part of the recent study on the impact of design defects on the change-proneness of software applications and extended it by performing an analysis based on ?ne-grained source code changes (SCCs) performed on Java classes during the evolution of the systems. Using SCCs extracted from the version control systems of 16 Java open-...

Investigation of the impact of cohesion on the change-proneness of Java interfaces

A lack of cohesion is often associated with bad software quality, and could lead to more changes and bugs in software. In this thesis the impact of cohesion on the change-proneness of Java interfaces is investigated. Showing the existence of a relation between these concepts can lead to better change prediction models that can support software...
