                         Preface by the BENEVOL 2022 Organizers

BENEVOL 2022, the 21st Belgium-Netherlands Software Evolution Workshop was held in
Mons, Belgium on September 12-13 2022.

Past editions of BENEVOL saw presentations on mining software repositories, source code
analysis and manipulation, software testing, bugs and socio-technical aspects in software
engineering. This year, the papers accepted at BENEVOL evolved around software
ecosystems, mining software repositories, software testing, open source software,
development, design and databases. More information about BENEVOL 2022 can be found

BENEVOL 2022 invited submissions of technical papers and presentation abstracts. Technical
papers concern novel results, possibly in the early stages of research and they are included
in the proceedings. On the other hand, presentation abstracts report research results that
are either already published or are novel results, so they are not included in the
proceedings. BENEVOL 2022 received 37 submissions in total; 22 presentation abstracts and
15 technical papers. All papers were reviewed by three referees. Ten technical papers were
accepted (out of 15 submissions) and 27 submissions were accepted as presentation
abstracts (including the five rejected technical papers). Thus, the proceedings include 10
technical papers; 7 of them are regular papers and 3 are short papers.

Two keynote speeches took place at BENEVOL 2022. Michail Papadakis (senior research
scientist at the University of Luxemburg, Luxemburg) gave the keynote speech “Applying
Mutation Testing in Evolving Systems”, while Gregorio Robles (Professor at the Universidad
Rey Juan Carlos, Spain) gave the second keynote “Let’s talk about bugs!”.

We would like to thank the program committee, the members of the organizing committee
and the student volunteers who contributed to have a very interactive BENEVOL 2022.
