29th International Conference on Fundamental Approaches to Software Engineering
FASE is concerned with the foundations on which software engineering is built.
Submissions should make novel contributions to making software engineering a more mature and soundly-based discipline. Contributions should be supported by appropriate arguments and validation. Contributions that combine the development of conceptual and methodological advances with their formal foundations and tool support are particularly encouraged. We welcome contributions to all such fundamental approaches, including:
Please find a list of accepted papers below:
The important dates are available in the Joint Call for Papers.
Selected papers from the FASE proceedings will be invited to submit an extended version to the Springer journal Formal Methods in System Design (FMSD). All publications in the special issue will be open access.
Detailed information on artifact evaluation can be found here.
FASE 2026 solicits four types of submissions: research papers, empirical evaluation papers, new ideas and emerging results (NIER) papers, tool demonstration papers and data showcase papers. Submissions must follow the formatting guidelines of Springer’s LNCS (use the llncs.cls class) and be submitted electronically in pdf through the Easychair author interface.
Research papers clearly identify and justify a principled advance to the fundamentals of software engineering. Research papers should clearly articulate their contribution, and provide sufficient evidence for the soundness and applicability of the proposed approach. Research papers are expected to be 15–18 pp (excluding bibliography). Additional material intended for reviewers but not for publication in the final version may be included in a clearly marked appendix.
Empirical evaluation papers evaluate existing software challenges or critically validate current proposed solutions with scientific means, i.e., by empirical studies, controlled experiments, rigorous case studies, simulations, etc. Scientific reflection on problems and practices in the software industry also falls into this category. We also encourage authors to replicate results from previous papers. A replicability study must go beyond simply re-implementing an algorithm and/or re-running the artifacts provided by the original paper, but should at least apply the approach to new, significantly broadened inputs, and clearly report on results that the authors were able to replicate as well as on aspects of the work that were not replicable. Empirical evaluation papers are expected to be 15–18 pp (excluding bibliography). Additional material intended for reviewers but not for publication in the final version may be included in a clearly marked appendix.
New Ideas and Emerging Results (NIER) papers seek to disrupt the status quo with forward-looking, thought-provoking, innovative research on the foundations of software engineering, as well as lessons learned from the past. Our aim is to accelerate the exposure of the ETAPS community to early yet potentially ground-breaking research results, and to techniques and perspectives that challenge the status quo. To broadly capture this goal, the NIER track at FASE 2026 will publish the following types of papers:
NIER papers are expected to be 6–8 pp (excluding bibliography). NIER papers will be assessed primarily on their level of originality, relevance, and potential for impact on the field in terms of promoting innovative thinking. Hence, inadequacies in the state-of-the-art and the pertinence, correctness, and impact of the idea/vision/lesson must be described clearly. A full evaluation is not required for FASE NIER papers, but preliminary evaluation results may help the reviewers understand the scope of the work better.
Tool demonstration papers and data showcase papers present a new tool, a new tool component, novel extensions to an existing tool, or a new dataset. They should provide a short description of the theoretical foundations and emphasize the design and implementation concerns, including software architecture. Tool papers should give a clear account of the tool’s functionality and discuss the tool’s practical capabilities with reference to the type and size of problems it can handle. Authors are strongly encouraged to make their tools publicly available, preferably on the web. Experimental evaluation is not required for tools, however, a motivation as to why the tool is interesting and significant should be provided. Dataset papers should describe the curation of datasets essential for software engineering research, replication studies, reporting of negative results, and insights gleaned from mining software repositories. Papers in this category are expected to be 6–8 pp (excluding bibliography). They should have an appendix of up to 6 additional pages with details on the actual demonstration.
FASE 2026 hosts the 8th edition of the Competition on Software Testing (Test-Comp 2026).
