VarMeR - A variability mechanisms recommender for software artifacts

Research output: Contribution to journalConference articlepeer-review


Software is typically not developed from scratch and reuse of existing artifacts is a common practice. Consequently, variants of artifacts exist, challenging maintenance and future development. In this paper, we present a tool for identifying variants in object-oriented code artifacts (in Java) and guiding their systematic reuse. The tool, called VarMeR - a Variability Mechanisms Recommender, utilizes known variability mechanisms, which are techniques applied to adapt generic (reusable) artifacts to the context of particular products, for both identification of variants and recommendation on systematic reuse. Building on ontological foundations for representing variability of software behaviors, VarMeR visually presents the commonality and variability of the classes in different products and recommendations on suitable polymorphism variability mechanisms to increase systematic reuse.
