One of the key mechanisms of object-oriented programming is inheritance. Some empirical studies show that classes inheriting behavior from more classes (i.e., ancestors) are more defect prone than the other classes. Since various collaborations are found among the instances of classes, classes are not isolated within the source code of object-oriented systems. In this paper, we investigate if classes...
Despite software history being indispensable for developers, there is little empirical knowledge about how they examine software history. Without such knowledge, researchers and tool builders are in danger of making wrong assumptions and building inadequate tools. In this paper we present an in-depth empirical study about the motivations developers have for examining software history, the strategies...
In the current demonstration we present a new instrument that provides for each existing class in an analyzed system information related to the problems the class reveals. We associate different types of problems to a class: design flaws, vulnerabilities and defects. In order to validate its usefulness, we perform some experiments on a suite of object-oriented systems and some results are briefly...
