Regression testing goals : View of practitioners and researchers

• Context: Regression testing is a well-researched area. However, the majority regression testing techniques proposed by the researchers are not getting the attention of the practitioners. Communication gaps between industry and academia and disparity in the regression testing goals are the main reasons. Close collaboration can help in bridging the communication gaps and resolving the disparities.Objective: The study aims at exploring the views of academics and practitioners about the goals of regression testing. The purpose is to investigate the commonalities and differences in their viewpoints and defining some common goals for the success of regression testing.Method: We conducted a focus group study, with 7 testing experts from industry and academia. 4 testing practitioners from 2companies and 3 researchers from 2 universities participated in the study. We followed GQM approach, to elicit the regression testing goals, information needs, and measures.Results: 43 regression testing goals were identified by the participants, which were reduced to 10 on the basis of similarity among the identified goals. Later during the priority assignment process, 5 goals were discarded, because the priority assigned to these goals was very low. Participants identified 47 information needs/questions required to evaluate the success of regression testing with reference to goal G5 (confidence). Which were then reduced to10 on the basis of similarity. Finally, we identified measures to gauge those information needs/questions, which were corresponding to the goal (G5).Conclusions: We observed that participation level of practitioners and researchers during the elicitation of goals and questions was same. We found a certain level of agreement between the participants regarding the regression testing definitions and goals.But there was some level of disagreement regarding the priorities of the goals. We also identified the need to implement a regression testing evaluation framework in the participating companies.
