Palomba, Fabio (author), Tamburri, Damian Andrew (author), Arcelli Fontana, Francesca (author), Oliveto, Rocco (author), Zaidman, A.E. (author), Serebrenik, Alexander (author)Code smells are poor implementation choices applied by developers during software evolution that often lead to critical flaws or failure. Much in the same way, community smells reflect the presence of organizational and socio-Technical issues within a software community that may lead to additional project costs. Recent empirical studies...journal article 2021

Vassallo, Carmine (author), Panichella, Sebastiano (author), Palomba, Fabio (author), Proksch, S. (author), Zaidman, A.E. (author), Gall, HC (author)Automatic static analysis tools (ASATs) are instruments that support code quality assessment by automatically detecting defects and design issues. Despite their popularity, they are characterized by (i) a high false positive rate and (ii) the low comprehensibility of the generated warnings. However, no prior studies have investigated the usage...journal article 2020

Catolino, G. (author), Palomba, F. (author), Zaidman, A.E. (author), Ferrucci, Filomena (author)Modern version control systems, e.g., GitHub, include bug tracking mechanisms that developers can use to highlight the presence of bugs. This is done by means of bug reports, i.e., textual descriptions reporting the problem and the steps that led to a failure. In past and recent years, the research community deeply investigated methods for...journal article 2019

Palomba, F. (author), Di Nucci, D. (author), Panichella, A. (author), Zaidman, A.E. (author), De Lucia, Andrea (author)Context. The demand for green software design is steadily growing higher especially in the context of mobile devices, where the computation is often limited by battery life. Previous studies found how wrong programming solutions have a strong impact on the energy consumption. Objective. Despite the efforts spent so far, only a little knowledge...journal article 2019

(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

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

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

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

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

Recently, researchers have suggested to add other non-coverage criteria, such as mem- ory consumption or readability, to increase the practical use- fulness of generated tests. In this paper, we observe that test code quality metrics, and test cohesion and...conference paper 2016
