ABSTRACT: In this paper we investigate factors of the testability of object-oriented software systems. The starting point is given by a study of the literature to obtain both an initial model of testability and existing OO metrics related to testability. Subsequently, these metrics are evaluated by means of two case studies of large Java systems for which JUnit test cases exist. The goal of this paper is to define and evaluate a set of metrics that can be used to assess the testability of the classes of a Java system.

ABSTRACT: Code implementing a crosscutting concern is often spread over many different parts of an application. Identifying such code automatically greatly improves both the maintainability and the evolvability of the application. First of all, it allows a developer to more easily find the places in the code that must be changed when the concern changes, and thus makes such changes less time consuming and less prone to errors. Second, it allows a developer to refactor the code, so that it uses modern and more advanced abstraction mechanisms, thereby restoring its modularity. In this paper, we evaluate the suitability of clone detection as a technique for the identification of crosscutting concerns. To that end, we manually identify four specific concerns in an industrial C application, and analyze to what extent clone detection is capable of finding these concerns. We consider our results as a stepping stone toward an automated "concern miner" based on clone detection.

ABSTRACT: This paper reports upon our experience in automatically migrating the crosscutting concerns of a large-scale software system, writ-ten in C, to an aspect-oriented implementation. We zoom in on one particular crosscutting concern, and show how detailed information about it is extracted from the source code, and how this information enables us to characterise this code and define an appropriate aspect automatically. Additionally, we compare the already existing solu-tion to the aspect-oriented solution, and discuss advantages as well as disadvantages of both in terms of selected quality attributes. Our results show that automated migration is feasible, and can lead to significant improvements in source code quality.
