*** Third Call for Papers *** 37th International Conference on Testing Software and Systems (ICTSS 2025) September 17-19, 2025, 5* St. Raphael Resort and Marina, Limassol, Cyprus https://conf.researchr.org/home/ictss-2025 (*** Proceedings to be published by Springer in LNCS ***) IFIP-ICTSS is a well-established conference where researchers, developers, testers, and users from industry get together to present and discuss the most recent innovations, experiences and open challenges related to testing software and systems and measuring software quality. Topics of interest include, but are not limited to: ■ AI for Software Testing and Testing of AI: the growing interest in the use of AI has also spread in to various aspects of software testing. In addition, work is underway to test and validate AI systems/applications (machine learning, expert systems, neural networks). ■ Aspects of testing: test derivation, test selection, test generation, test coverage, test concretization, test implementation and execution, test result analysis, test oracle, verdict computation, test management, active testing and passive testing, monitoring and runtime verification. ■ Testing new technologies: this year we encourage submissions focused on testing Large Language Models (LLMs), audit machine learning systems (especially for applications to Health) and Quantum systems (programs, computers, and simulators). ■ Diversity on testing: diverse generation, selecting diverse test suites, foundations of testing and diversity, applications of entropy and Kolmogorov complexity on test suite diversity. ■ Theoretical approaches: formalisms (such as automata, state machines, process algebra, logics, Markov-chains...), testing frameworks, results for compositionality, refinement, soundness and completeness, addressing complex systems, heterogeneous or hybrid systems. ■ Modelling languages (such as UML, MATLAB, Simulink, Modelica...) and associated tooling for model-based testing: test generation from models, model-based oracles. Scalability, traceability, quantification issues. Automated support of any parts of the testing activities, testing processes, test-driven development, sound metrics and measurements. ■ Testing of quality aspects: Functional, interoperability, unit, integration, performance, load, conformance, non-regression, reliability, robustness. ■ Security Testing: methodologies and techniques for continuous security assessment, security monitoring, security review, penetration testing, verification of certification compliance; automation of security testing processes. ■ Testing emerging technologies: quantum systems (programs, computers, and simulators), genetic algorithms, metaverse, and any other technology in the early stages of testing. ■ Human Aspects of Testing: human psychology and management attitude play major roles in formulating and adopting testing in practice. ■ Cross domains and combination of techniques: using other techniques such as proof, model-checking, symbolic execution, abstract interpretation, static analysis, simulation, model learning, ... to improve quality and reduce the effort in testing processes. ■ Cross domains and combination of techniques: using other techniques such as proof, model-checking, symbolic execution, abstract interpretation, static analysis, simulation, model learning, machine learning, expert systems, neural networks, genetic algorithms... to improve quality and reduce the effort in testing processes. ■ Application aspects and case studies: Communicating systems such as cyberphysical systems, systems of systems, embedded systems, web services systems, smart grids, cloud computing systems, business information systems, real-time systems, distributed and concurrent systems. Case studies and industrial applications involving qualified empirical evaluations. IFIP-ICTSS Invites: Full papers (12 to 15 pages plus at most 2 extra pages for references in the one-column Springer LNCS format) describing original research contributions with sufficient evidence for the interest of the proposed approach. Industry papers (12 to 15 pages plus at most 2 extra pages for references in the one-column Springer LNCS format) describing original research or experience report conducted within an industrial environment or in collaboration with an industry partner. Short papers or work-in-progress papers (up to 6 pages plus at most 1 extra page for references in the one-column Springer LNCS format) describing academic work in progress or tool implementations, as well as testing processes, achievements and feedback on testing methods for industrial case studies. Journal-First. The aim of the Journal-First (JF) submission category is to further enrich the program of ICTSS, as well as to provide an overall more flexible path to publication and dissemination of original research that is within the scope of ICTSS. A submission in this category must adhere to the following criteria: ■ It should be clearly within the scope of the conference. ■ It should be recent: it should have been accepted and made publicly available in a journal (online or in print) by January 1, 2023 or more recently. ■ It has not been presented at, and is not under consideration for, Journal- First tracks of other conferences or workshops. ■ The submission has to be in the form of a 4-page extended abstract and has to provide a concise summary of the published journal paper. ■ It must be marked as such in the submission’s, and must explicitly include full bibliographic details (including a DOI) of the journal publication they are based on. Since the referenced journal papers have already been reviewed and accepted by the corresponding journals, submissions in the JF category will not be reviewed again for technical content. Submissions will be judged on the basis of the above criteria, but also considering how well they would complement the conference’s technical program. Accepted submissions in this category will be part of the proceedings of ICTSS 2025, with the title equal to the original title of the article with the prefix. The submission link is: https://easychair.org/my/conference?conf=ictss2025 The papers will be published by Springer in the LNCS volume. Authors should consult Springer’s Instructions for Authors of Proceedings (https://www.springer.com/gp/computer-science/lncs/conference-proceedings-gui...) and use either the LaTeX or the Word templates provided on the authors’ page. Springer’s proceedings LaTeX templates are available in Overleaf. Authors are encouraged to include their ORCIDs in their papers. Journal Special Issue Best papers of the conference will be invited to submit an extended version of their article at a special (topical) issue of the Springer Nature of Computer Science (https://link.springer.com/journal/42979). Deadline will be near the end of December 2025 with a tentative publication date for the middle 2026. Collocation ICTSS 2025 will be collocated with the 19th European Conference on Software Architecture (https://conf.researchr.org/home/ecsa-2025).
