“…From the 29 offline evaluations, most (51.72%) focuses on reviewer recommenders. Approaches to support code checking are the second most common (34.48%) [109,114,117,119,138,141,142,145,148,143]. From the remaining works, two target review prioritization support [135,137], and the last two studies evaluate feedback provision assistance [21] and a variation in the MCR process [150].…”

“…Support for code checking has been focused on providing information to ease the manual work of reviewers, mainly the understanding of a change. To provide this support, the main strategies presented in the studies are (i) provide visualizations of code changes [109,138,114,119,111,117,141,142,148,143], (ii) present properties associated with them [131,121,130], and (iii) support the analysis of change impact [133,145].…”

“…Some proposals assume that a change can be decomposed to ease understanding. ClusterChanges [109], JClus-terChanges [138], CoRA [142], and ChgCutter [148] are techniques for decomposing changes based on static analysis. ClusterChanges and JClusterChanges, instantiated for C# and Java language, respectively, analyze composite changes to uncover definitions and their uses, clustering diff-regions into trivial and non-trivial.…”

“…Studies of this type are present in six (13.64%) papers. From these, four [109,111,148,142] were used to complement the results of another study detailed in the same publication. One study [107] consists of a preliminary evaluation in which the subjects interact with a prototype of the proposed approach.…”

Context: Modern Code Review (MCR) is a widely known practice of software quality assurance. However, the existing body of knowledge of MCR is currently not understood as a whole. Objective: Our goal is to identify the state of the art on MCR, providing a structured overview and an in-depth analysis of the research done in this field. Method: We performed a systematic literature review, selecting publications from four digital libraries. Results: A total of 139 papers were selected and analyzed in three main categories. Foundational studies are those that analyze existing or collected data from the adoption of MCR. Proposals consist of techniques and tools to support MCR, while evaluations are studies to assess an approach or compare a set of them. Conclusion: The most represented category is foundational studies, mainly aiming to understand the motivations for adopting MCR, its challenges and benefits, and which influence factors lead to which MCR outcomes. The most common types of proposals are code reviewer recommender and support to code checking. Evaluations of MCR-supporting approaches have been done mostly offline, without involving human subjects. Five main research gaps have been identified, which point out directions for future work in the area.

An exploratory study on confusion in code reviews

et al. 2021

Context Code review is a widely used technique of systematic examination of code changes which aims at increasing software quality. Code reviews provide several benefits for the project, including finding bugs, knowledge transfer, and assurance of adherence to project guidelines and coding style. However, code reviews have a major cost: they can delay the merge of the code change, and thus, impact the overall development process. This cost can be even higher if developers do not understand something, i.e., when developers face confusion during the code review. Objective This paper studies the phenomenon of confusion in code reviews. Understanding confusion is an important starting point to help reducing the cost of code reviews and enhance the effectiveness of this practice, and hence, improve the development process. Method We conducted two complementary studies. The first one aimed at identifying the reasons for confusion in code reviews, its impacts, and the coping strategies developers use to deal with it. Then, we surveyed developers to identify the most frequently experienced reasons for confusion, and conducted a systematic mapping study of solutions proposed for those reasons in the scientific literature. Results From the first study, we build a framework with 30 reasons for confusion, 14 impacts, and 13 coping strategies. The results of the systematic mapping study shows 38 articles addressing the most frequent reasons for confusion. From those articles, we found 13 different solutions for confusion proposed in the literature, and five impacts were established related to the most frequent reasons for confusion. Conclusions Based on the solutions identified in the mapping study, or the lack of them, we propose an actionable guideline for developers on how to cope with confusion during code reviews; we also make several suggestions how tool builders can support code reviews. Additionally, we propose a research agenda for researchers studying code reviews.
