2020

SATToSE is the Seminar Series on Advanced Techniques & Tools for Software Evolution. Its 13th edition will take place in Amsterdam (the Netherlands) on July 1-2, 2020. Past editions of SATToSE saw presentations on software visualisation techniques, tools for co-evolving various software artefacts, their consistency management, runtime adaptability and context-awareness, as well as empirical results about software evolution. SATToSE will host invited talks, paper presentations, tutorials, and a hackathon, fostering interactions among participants and stimulating lively debates and discussions around the topics of interest of the event. We expect attendees to be active participants and not just passive listeners. Presenters should be open to and encourage questions and discussions during their talks.

The goal of SATToSE is to gather both undergraduate and graduate students to showcase their research, exchange ideas, improve their communication skills, attend and contribute technology showdown and hackathons.

Given the current situation with COVID-19, the organizing and steering committee of SATToSE have decided to hold SATToSE 2020 virtually.

Keynote Speakers

Anne Etien
"Rotten Green Tests": Rotten Green Tests are tests that appear to pass, but which contain assertions that are not executed. As a test smell, it is one of the worst; the code under test appears to be valid despite not having been tested. We initially identified this concepts on projects in the Pharo language environment. We now show that Rotten Green Tests also exist in Java and Python projects.
For each of the three language environments, we conducted an empirical evaluation of around one hundred mature projects, taking into account test helper methods, inherited helpers, and trait composition. Our results show that rotten green tests are present in Java and Python as well as Pharo, and that they fall into similar categories in all these languages. Furthermore, we found bugs in code that were hidden by rotten tests in two languages. Finally, we discuss two potentially new smells concerning the misuse of testing frameworks that we saw in all three languages.

Anne Etien will be full professor at the Université de Lille from September 2020. She received a PhD degree from Université of Paris 1, France, in 2006. She is a member of Inria Lille and the RMoD team. Her research interests concern reengineering and evolution of complex legacy systems. She supervised 8 PhD students, published around 50 articles mainly in international conference or journal paper. Finally, she is member of various program committees such as ICSME 2020 or ICSE 2021 and was Sattose 2019 program chain in Bolzano.

"On the fragility of open source software packaging ecosystems": In the last couple of years, the Software Engineering Lab of the University of Mons has extensively studied different aspects of open source software package management ecosystems (including among others Cargo, npm, Packagist and Rubygems). These ecosystems contain a large number of package releases with many interdependencies. They face challenges related to their scale, complexity and rate of evolution. Typical problems are backward incompatible package updates, and the increasing proportion of "fragile" packages due to an excessive number of transitive dependencies. This talk reports on our findings based on multiple empirical studies that we have conducted to understand different aspects of dependency management and their practical implications. In particular, we focus on the outdatedness of package dependencies, measurable with the concept of "technical lag"; as well as on the implications of package dependency constraints on respecting the semantic versioning policy.

Tom Mens is full professor at the University of Mons, Belgium, where he has been directing the Software Engineering Lab for over 15 years. He co-edited two Springer books “Software Evolution” and “Evolving Software Systems” and published numerous highly-cited software engineering articles in peer-reviewed international software engineering conferences and journals. His current research revolves around empirical software engineering, software evolution, software ecosystems, and open source software health. He is coordinator of the Belgian FNRS-FWO Excellence of Science project SECO-ASSIST (https://secoassist.github.io)

Hackathon

The Software Improvement Group (SIG) will host the SATToSE 2020 hackathon with call graph data in the context of the FASTEN project. Stay tuned!

Programme

All sessions will take place on Zoom (provided by the UvA). To facilitate some social interaction, we would kindly ask participants to personalize their Zoom profile photo and try to turn on your camera at least during the Q&A part of each talk. Many thanks!

Contributions are solicited on all aspects of software and model evolution, practices, and technologies. In particular, we encourage submissions about the following (non-exhaustive) list of topics:

  • Supporting tools, processes, and models for managing software evolution
  • Industrial needs, case studies and experiences
  • Software analytics and visualisation techniques to support software evolution
  • Empirical studies in evolution and maintenance
  • Program transformation, refactoring, renovation, and migration

SaTToSE 2020 aims to increase the interaction between PhD students and more experienced researchers. For this reason, SATToSE will introduce for the first time the “mentor” concept. Each PhD student submitting a Work-in-Progress paper will have a senior member as a mentor during the seminar (different than their PhD supervisor). The goal is to stimulate discussion between PhD students and senior researchers to provide feedback on their research and promote discussions and collaborations.

Submission Guidelines

Contributions are managed through EasyChair. Please submit your paper using the following link:
https://easychair.org/conferences/?conf=sattose2020
We solicit papers/abstracts of up to 5 pages, in one of the following forms:

  • Work in Progress (5-page limit + up to 2 pages of references): Early ideas and achievements that you want to share with the community and get feedback on.
  • Publication Summary (3-page limit+ up to 2 pages of references): Overview of research results already published or ready to be submitted to a conference or a journal.
  • Artifact Presentation (5-page limit + up to 2 pages of references): Technical explanation of important features of an artifact (e.g., tool, library, data set, test suite, methodology)

To submit your contribution, you need to specify:

  • title of the presentation
  • list of author(s)
  • extended abstract of your presentation
  • desired category of your work as a subtitle and as a topic on easychair (Work in Progress, Publication Summary, or Artifact Presentation)

Please adhere to this latex style, two column style (paper2p.tex and twocolpceurws.sty). This format is compatible with the the CEUR Workshop Proceedings.

All submissions will be reviewed and screened for scope and compatibility by the program committee, which will provide feedback for improving the abstract and preparing the talk. All contributions accepted for presentation will receive 10–30 minutes during the event for presentation and discussion. Submitters will also be offered the opportunity to receive feedback and guidance to improve their submission towards a formally published paper, in a SATToSE post-proceedings issue of an open access journal. Please note that authors of publication summaries cannot publish their SATToSE summary as their work is already published.

All the presented slides and pointers to related resources will be collected and will be made publicly available.
