Aniche, Maurício (author), Treude, Christoph (author), Zaidman, A.E. (author), van Deursen, A. (author), Gerosa, Marco Aurélio (author)Code metric analysis is a well-known approach for assessing the quality of a software system. However, current tools and techniques do not take the system architecture (e.g., MVC, Android) into account. This means that all classes are assessed similarly, regardless of their specific responsibilities. In this paper, we propose SATT (Software...conference paper 2016

Aniche, Maurício (author), Bavota, Gabriele (author), Treude, Christoph (author), van Deursen, A. (author), Gerosa, Marco Aurélio (author)Code smells are symptoms of poor design and implementation choices that may hinder code comprehension, and possibly increase change-and defect-proneness. A vast catalogue of smells has been defined in the literature, and it includes smells that can be found in any kind of system (e.g., God Classes), regardless of their architecture. On the other...conference paper 2016

(author)Teaching software architecture is hard. The topic is abstract and is best understood by experiencing it, which requires proper scale to fully grasp its complexity. Furthermore, students need to practice both technical and social skills to become good software architects. To overcome these teaching challenges, we developed the Collaborative...conference paper 2017

Wieman, Rick (author), Aniche, Maurício (author), Lobbezoo, Willem (author), Verwer, S.E. (author), van Deursen, A. (author)Passive learning techniques infer graph models on the behavior of a system from large trace logs. The research community has been dedicating great effort in making passive learning techniques more scalable and ready to use by industry. However, there is still a lack of empirical knowledge on the usefulness and applicability of such techniques in...conference paper 2017

Tómasdóttir, Kristín Fjóla (author), Aniche, Maurício (author), van Deursen, A. (author)Automatic static analysis tools help developers to automatically spot code issues in their software. They can be of extreme value in languages with dynamic characteristics, such as JavaScript, where developers can easily introduce mistakes which can go unnoticed for a long time, e.g., a simple syntactic or spelling mistake. Although research has...conference paper 2017

Spadini, D. (author), Aniche, Maurício (author), Bruntink, Magiel (author), Bacchelli, A. (author)When writing automated unit tests, developers often deal with software artifacts that have several dependencies. In these cases, one has the possibility of either instantiating the dependencies or using mock objects to simulate the dependencies' expected behavior. Even though recent quantitative studies showed that mock objects are widely used...conference paper 2017

Aniche, Maurício (author), Treude, Christoph (author), Steinmacher, Igor (author), Wiese, Igor (author), Pinto, Gustavo (author), Storey, Margaret Anne (author), Gerosa, Marco Aurélio (author)Many developers rely on modern news aggregator sites such as reddit and hn to stay up to date with the latest technological developments and trends. In order to understand what motivates developers to contribute, what kind of content is shared, and how knowledge is shaped by the community, we interviewed and surveyed developers that participate...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

Aniche, Maurício (author), Bavota, Gabriele (author), Treude, Christoph (author), Gerosa, Marco Aurélio (author), van Deursen, A. (author)Previous studies have shown the negative effects that low-quality code can have on maintainability proxies, such as code change- and defect-proneness. One of the symptoms for low-quality code are code smells, defined as sub-optimal implementation choices. While this definition is quite general and seems to suggest a wide spectrum of smells that...journal article 2018

Treude, Christoph (author), Aniche, Maurício (author)The documentation of popular APIs is spread across many formats, from vendor-curated reference documentation to Stack Overflow threads. For developers, it is often not obvious from where a particular piece of information can be retrieved. To understand this documentation landscape, we systematically conducted Google searches for the elements of...conference paper 2018

Aué, J. (author), Aniche, Maurício (author), Lobbezoo, Maikel (author), van Deursen, A.

The capabilities and complexity of Web APIs differ from service to service, and therefore the impact of API errors varies. API problem cases related to Adyen's payment service were found to have...conference paper 2018

These SQL commands can range from very simple selections to queries that involve several tables, subqueries, and grouping operations. And, as with any important piece of code, developers should properly test SQL queries. In order to completely test a SQL...conference paper 2018

However, with the increased complexity and heterogeneity of contemporary software, this might not be enough. This...conference paper 2019
