Model-based test case prioritization: A systematic literature review

Abstract

Re-testing all test cases during regression testing is costly and time-consuming. These problems motivate researchers to come up with various techniques to overcome them. One of the techniques is Test Case Prioritization that prioritizes test cases in test suite by ordering them according to a desired objective goal. Model-based is one of the approaches which utilizes the system models to make prioritization. The main purpose of this systematic review is to identify and categorize the current state-of-the-art while providing a baseline for future research in model-based Test Case Prioritization. A general search term related to model-based approach was used during the study search in selected digital libraries ranging from 2005 to 2016 to find primary studies that propose model-based approach. A total of 32 primary studies consisting of 21 combinations of conference proceedings, workshop, and symposium and 12 journal articles were finalized after going through a strict selection process. A sum of 48 distinct approaches with their respective characteristics and models used have been identified, and some general constraints of model-based Test Case Prioritization have been highlighted. Future research is recommended to put more focus in detailing the introduced category to benefit the researchers and practitioners.
