Title: The Role of Similarity in Detecting Feature Interaction in Software Product Lines

Abstract: As a software product line evolves, it typically introduces new features and includes new products over time. A feature is a unit of functionality. Unwanted feature interactions, wherein one feature hinders another feature‚Äôs operation, are a significant problem, especially as large software product lines evolve. This can lead to failures, performance degradation, and hazardous states in a new product. Software product line developers currently identify new, unwanted feature interactions primarily in the testing of each new product. This incurs significant costs, comes late in development, and does not exploit the knowledge of prior feature interactions within a product line. The contribution of our work is to leverage knowledge of prior feature interactions in a software product line, together with similarity measures between the features in known feature interactions and the new features, in order to detect similar feature interactions in a new product much earlier in the development process. Results from application to three small software product lines from the literature show that this approach accurately detected 69% to 73% of feature interactions.
