Spadini, D. (author), Schvarcbacher, Martin (author), Oprescu, Ana (author), Bruntink, Magiel (author), Bacchelli, A. (author)Test smells are poor design decisions implemented in test code, which can have an impact on the effectiveness and maintainability of unit tests. Even though test smell detection tools exist, how to rank the severity of the detected smells is an open research topic. In this work, we aim at investigating the severity rating for four test smells...conference paper 2020

Spadini, D. (author), Calikli, Gul (author), Bacchelli, A. (author)In contemporary code review, the comments put by reviewers on a specific code change are immediately visible to the other reviewers involved. Could this visibility prime new reviewers' attention (due to the human's proneness to availability bias), thus biasing the code review outcome In this study, we investigate this topic by conducting a...conference paper 2020

di Biase, M. (author), Bruntink, Magiel (author), van Deursen, A. (author), Bacchelli, A. (author)Background: Code review is a cognitively demanding and time-consuming process. Previous qualitative studies hinted at how decomposing change sets into multiple yet internally coherent ones would improve the reviewing process. So far, literature provided no quantitative analysis of this hypothesis.<br/>Aims: (1) Quantitatively measure the effects...journal article 2019

Kovalenko, V.V. (author), Bogomolov, Egor (author), Bryksin, Timofey (author), Bacchelli, A. (author)One recent, significant advance in modeling source code for machine learning algorithms has been the introduction of path-based representation - an approach consisting in representing a snippet of code as a collection of paths from its syntax tree. Such representation efficiently captures the structure of code, which, in turn, carries its...conference paper 2019

Kovalenko, V.V. (author), Tintarev, N. (author), Pasynkov, Evgeny (author), Bird, Christian (author), Bacchelli, A. (author)Selecting reviewers for code changes is a critical step for an efficient code review process. Recent studies propose automated reviewer recommendation algorithms to support developers in this task. However, the evaluation of recommendation algorithms, when done apart from their target systems and users (i.e., code review tools and change...journal article 2019

Pascarella, L. (author), Palomba, F. (author), Bacchelli, A. (author)Defect prediction models focus on identifying defect-prone code elements, for example to allow practitioners to allocate testing resources on specific subsystems and to provide assistance during code reviews. While the research community has been highly active in proposing metrics and methods to predict defects on long-term periods (i.e.,at...journal article 2019

Spadini, D. (author), Palomba, F. (author), Baum, Tobias (author), Hanenberg, Stefan (author), Bruntink, Magiel (author), Bacchelli, A. (author)Test-Driven Code Review (TDR) is a code review practice in which a reviewer inspects a patch by examining the changed test code before the changed production code. Although this practice has been mentioned positively by practitioners in informal literature and interviews, there is no systematic knowledge of its effects, prevalence, problems, and...conference paper 2019

Pascarella, L. (author), Bruntink, Magiel (author), Bacchelli, A. (author)Code comments are a key software component containing information about the underlying implementation. Several studies have shown that code comments enhance the readability of the code. Nevertheless, not all the comments have the same goal and target audience. In this paper, we investigate how 14 diverse Java open and closed source software...journal article 2019

Sawant, A.A. (author), Robbes, Romain (author), Bacchelli, A. (author)Application Programming Interfaces (API) provide reusable functionality to aid developers in the development process. The features provided by these APIs might change over time as the API evolves. To allow API consumers to peacefully transition from older obsolete features to new features, API producers make use of the deprecation mechanism...journal article 2019

Pascarella, L. (author), Spadini, D. (author), Palomba, F. (author), Bruntink, Magiel (author), Bacchelli, A. (author)Contemporary code review is a widespread practice used by software engineers to maintain high software quality and share project knowledge. However, conducting proper code review takes time and developers often have limited time for review. In this paper, we aim at investigating the information that reviewers need<br/>to conduct a proper code...journal article 2018

Sawant, A.A. (author), Huang, Guangzhe (author), Vilen, Gabriel (author), Stojkovski, Stefan (author), Bacchelli, A. (author)In this study, we investigate why API producers deprecate features. Previous work has shown us that knowing the rationale behind deprecation of an API aids a consumer in deciding to react, thus hinting at a diversity of deprecation reasons. We manually analyze the Javadoc of 374 deprecated methods pertaining four mainstream Java APIs to see...conference paper 2018

Pascarella, L. (author), Palomba, F. (author), Di Penta, Massimiliano (author), Bacchelli, A. (author)Recent research has provided evidence that, in the industrial context, developing video games diverges from developing software systems in other domains, such as office suites and system utilities. In this paper, we consider video game development in the open source system (OSS) context. Specifically, we investigate how developers contribute to...conference paper 2018

Sawant, A.A. (author), Aniche, Maurício (author), van Deursen, A. (author), Bacchelli, A. (author)Deprecation is a language feature that allows API producers to mark a feature as obsolete. We aim to gain a deep understanding of the needs of API producers and consumers alike regarding deprecation. To that end, we investigate why API producers deprecate features, whether they remove deprecated features, how they expect consumers to react, and...conference paper 2018

Spadini, D. (author), Palomba, F. (author), Zaidman, A.E. (author), Bruntink, Magiel (author), Bacchelli, A. (author)Test smells are sub-optimal design choices in the implementation of test code. As reported by recent studies, their presence might not only negatively affect the comprehension of test suites but can also lead to test cases being less effective in finding bugs in production code. Although significant steps toward understanding test smells, there...conference paper 2018

Pascarella, L. (author), Geiger, Franz-Xaver (author), Palomba, F. (author), Di Nucci, Dario (author), Malavolta, Ivano (author), Bacchelli, A. (author)To gain a deeper empirical understanding of how developers work on Android apps, we investigate self-reported activities of Android developers and to what extent these activities can be classified with machine learning techniques. To this aim, we firstly create a taxonomy of self-reported activities coming from the manual analysis of 5,000...conference paper 2018
