Abstract
Feature traceability refers to the ability to locate features in software artifacts. Traceability helps developers to identify relevant artifacts during development and maintenance. Feature-oriented programming already establishes a one-to-one mapping between features and artifacts, whereas conditional compilation comes with a many-to-many mapping. While all artifacts belonging to a feature are contained in a single feature module, the inherent complexity of variable software poses challenges for developers. The interaction of a feature module with other feature modules can easily lead to unwanted feature interactions. Thus, developers need support to understand which other feature modules are also relevant for their intended changes. In addition, debugging feature-oriented programs is typically challenging, as during the composition of feature modules the mapping disappears.
