Help Me to Understand this Commit! – A Vision for Contextualized Code Reviews
CoRR(2024)
摘要
Background: Modern Code Review (MCR) is a key component for delivering
high-quality software and sharing knowledge among developers. Effective reviews
require an in-depth understanding of the code and demand from the reviewers to
contextualize the change from different perspectives. Aim: While there is a
plethora of research on solutions that support developers to understand changed
code, we have observed that many provide only narrow, specialized insights and
very few aggregate information in a meaningful manner. Therefore, we aim to
provide a vision of improving code understanding in MCR. Method: We classified
53 research papers suggesting proposals to improve MCR code understanding. We
use this classification, the needs expressed by code reviewers from previous
research, and the information we have not found in the literature for
extrapolation. Results: We identified four major types of support systems and
suggest an environment for contextualized code reviews. Furthermore, we
illustrate with a set of scenarios how such an environment would improve the
effectiveness of code reviews. Conclusions: Current research focuses mostly on
providing narrow support for developers. We outline a vision for how MCR can be
improved by using context and reducing the cognitive load on developers. We
hope our vision can foster future advancements in development environments.
