Together We Are Stronger: EvidenceBased Reflections on IndustryAcademia Collaboration in Software Testing For a highly relevant and applied research area like software testing industryacademia collaboration is of uttermost importance. In this paper we reflect on how industryacademia collaboration can be improved based on evidence from four empirical studies. We therefore first present four studies providing evidence on the (1) perceived level of challenges in testing activities, (2) focus areas in industrial and academic software testing conferences, (3) synergies between industrial and academic software testing conferences, as well as (4) the need for consideration of grey literature. Then, we reflect on issues, which we think can improve the link and synergies between industry and academia in software testing, i.e., research topics, guidelines and evidence, value and risk, context and scalability, action research and education as well as grey literature and open science.

Code Reviews, Software Inspections, and Code Walkthroughs: Systematic Mapping Study of Research Topics Code reviews have been used to improve code quality since the 1970s. Most practitioners in the field of software have some experience with respect to the technique. In this mapping study we illustrate what kinds of research questions are addressed in code review literature. The following themes emerged from analysis of 75 original articles: (1) description or comparison of different code review practices, (2) behavior of reviewers (e.g., eye tracking studies), (3) communication and teamwork, (4) outcomes of code reviews (e.g., what kinds of problems are identified), (5) how properties of code to be reviewed affect reviewing, and (6) reasons for conducting code reviews. About half of the studies have been conducted with students and novices. The numbers of industry papers has significantly increased when compared to the previous reviews in the field.
