Live Programming and Software Evolution: Questions during a Programming Change Task

Several studies provide the questions developers ask during software evolution tasks, providing foundations for subsequent work. Nevertheless, none of them focus on Live Programming environments that gain in popularity as they are perceived to have a positive effect on programming tasks. Studying the impact of a Live Programming environment on software development activities is thus the goal of this study. In a partial replication of the study by Sillito et al., we conducted 17 software evolution sessions in a Live Programming environment and report 1,161 developer questions asked during these sessions. We contrast our results with the results by Sillito et al., focusing on the question occurrences, question complexity and what information participants used to gain a required knowledge. We report eight new questions and observe that the Live Programming facilities do have an impact on the way developers ask questions about source code and use tools to gain corresponding knowledge.
