A Collaborative Filtering Recommender System for Test Case Prioritization in Web Applications
This work addresses test case prioritization for web application developers, but it is incremental as it applies an existing recommender method to a new domain.
The authors tackled the problem of test case prioritization in web applications by implementing an item-based collaborative filtering recommender system, which improved effectiveness compared to four control techniques in an empirical study with three web applications.
The use of relevant metrics of software systems could improve various software engineering tasks, but identifying relationships among metrics is not simple and can be very time consuming. Recommender systems can help with this decision-making process, many applications have utilized these systems to improve the performance of their applications. To investigate the potential benefits of recommender systems in regression testing, we implemented an item-based collaborative filtering recommender system that uses user interaction data and application change history information to develop a test case prioritization technique. To evaluate our approach, we performed an empirical study using three web applications with multiple versions and compared four control techniques. Our results indicate that our recommender system can help improve the effectiveness of test prioritization.
