(author)“There can be no vulnerability without risk; there can be no community without vulnerability; there can be no peace, and ultimately no life, without community.” - [M. Scott Peck]<br/><br/>The open-source phenomenon has reached the point in which it is virtually impossible to find large applications that do not rely on it. Such grand adoption may...journal article 2019

Beller, M.M. (author), Gousios, G. (author), Panichella, A. (author), Proksch, Sebastian (author), Amann, Sven (author), Zaidman, A.E. (author)Software testing is one of the key activities to achieve software quality in practice. Despite its importance, however, we have a remarkable lack of knowledge on how developers test in real-world projects. In this paper, we report on a large-scale field study with 2,443 software engineers whose development activities we closely monitored over...journal article 2019

Elazhary, Omar (author), Storey, Margaret-Anne (author), Ernst, Neil (author), Zaidman, A.E. (author)Developer contribution guidelines are used in social coding sites like GitHub to explain and shape the process a project expects contributors to follow. They set standards for all participants and 'save time and hassle caused by improperly created pull requests or issues that have to be rejected and re-submitted' (GitHub). Yet, we lack a...conference paper 2019

Catolino, G. (author), Palomba, F. (author), Zaidman, A.E. (author), Ferrucci, Filomena (author)The impact of developers' experience on several development practices has been widely investigated in the past. One of the most promising research fields is software testing, as many researchers found significant correlations between developers' experience and testing effectiveness. In this paper, we aim at further studying this relation, by...conference paper 2019

Catolino, G. (author), Palomba, F. (author), Arcelli Fontana, Francesca (author), De Lucia, Andrea (author), Zaidman, A.E. (author), Ferrucci, Filomena (author)Code smells are sub-optimal implementation choices applied by developers that have the effect of negatively impacting, among others, the change-proneness of the affected classes. Based on this consideration, in this paper we conjecture that code smell-related information can be effectively exploited to improve the performance of change...journal article 2019

Danglot, Benjamin (author), Vera-Perez, Oscar (author), Yu, Zhongxing (author), Zaidman, A.E. (author), Monperrus, Martin (author), Baudry, Benoit (author)The adoption of agile approaches has put an increased emphasis on testing, resulting in extensive test suites. These suites include a large number of tests, in which developers embed knowledge about meaningful input data and expected properties as oracles. This article surveys works that exploit this knowledge to enhance manually written...journal article 2019

Palomba, F. (author), Panichella, A. (author), Zaidman, A.E. (author), Oliveto, Rocco (author), De Lucia, Andrea (author)Code smells are symptoms of poor design or implementation choices that have a negative effect on several aspects of software maintenance and evolution, such as program comprehension or change- and fault-proneness. This is why researchers have spent a lot of effort on devising methods that help developers to automatically detect them in source...journal article 2018

Di Nucci, D. (author), Panichella, A. (author), Zaidman, A.E. (author), De Lucia, Andrea (author)Regression testing is performed during maintenance activities to assess whether the unchanged parts of a software behave as intended. To reduce its cost, test case prioritization techniques can be used to schedule the execution of the available test cases to increase their ability to reveal regression faults earlier. Optimal test ordering can be...journal article 2018

Beller, M.M. (author), Spruit, Niels (author), Zaidman, A.E. (author), Spinellis, D. (author)Debugging is an inevitable activity in most software projects, often difficult and more time-consuming than expected, giving it the nickname the “dirty little secret of computer science.” Surprisingly, we have little knowledge on how software engineers debug software problems in the real world, whether they use dedicated debugging tools, and how...conference paper 2018

Adams, Bram (author), Baudry, Benoit (author), Eldh, Sigrid (author), Zaidman, A.E. (author)This report documents the program and the outcomes of Dagstuhl Seminar 18122 "Automatic Quality Assurance and Release". The main goal of this seminar was to bridge the knowledge divide on how researchers and industry professionals reason about and implement DevOps for automatic quality assurance. Through the seminar, we have built up a common...report 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

Palomba, F. (author), Zaidman, A.E. (author), De Lucia, Andrea (author)Software testing is a key activity to control the reliability of production code. Unfortunately, the effectiveness of test cases can be threatened by the presence of faults. Recent work showed that static indicators can be exploited to identify testrelated issues. In particular test smells, i.e., sub-optimal design choices applied by developers...conference paper 2018

Catolino, G. (author), Palomba, F. (author), De Lucia, Andrea (author), Ferrucci, Filomena (author), Zaidman, A.E. (author)Continuous changes applied during software maintenance risk to deteriorate the structure of a system and are a threat to its maintainability. In this context, predicting the portions of source code where specific maintenance operations should be focused on may be crucial for developers to prevent maintainability issues. Previous work proposed...journal article 2018

Zhu, Q. (author), Panichella, Annibale (author), Zaidman, A.E. (author)Mutation testing is widely considered as a high-end test coverage criterion due to the vast number of mutants it generates. Although many efforts have been made to reduce the computational cost of mutation testing, in practice, the scalability issue remains. In this paper, we explore whether we can use compression techniques to improve the...conference paper 2018

Zhu, Q. (author), Panichella, A. (author), Zaidman, A.E. (author)Mutation testing has been very actively investigated by researchers since the 1970s, and remarkable advances have been achieved in its concepts, theory, technology, and empirical evidence. While the most influential realisations have been summarised by existing literature reviews, we lack insight into how mutation testing is actually applied....journal article 2018
