10th International Workshop on Metamorphic Testing (MET 2026)

Goal of the workshop

The workshop aims to foster cooperation among practitioners and researchers of software engineering, especially software quality assurance, and in particular, software testing. It provides a platform for the discussion of novel ideas, new perspectives, new applications, and state-of-the-art research, related to or inspired by Metamorphic Testing (MT).

Workshop theme

Metamorphic Testing (MT) is a testing technique that exploits the relationships among the inputs and outputs of multiple executions of the program under test: These are called Metamorphic Relations (MRs). MT has been proven highly effective in testing programs that face the oracle problem – a major challenge for software testing and software quality assurance, where the correctness of individual outputs is difficult (or impossible) to determine. Since its introduction in the late 1990s, interest in MT has grown immensely, with numerous applications in various domains such as machine learning, bioinformatics, computer graphics, simulations, search engines, decision support, cloud computing, databases, compilers, and large language models (LLMs). The 10th International Workshop on Metamorphic Testing (MET) will bring together researchers and practitioners in academia and industry to discuss research results and experiences.

Some topics of interest include, but are not limited to, the following:
▪ Emerging and innovative applications of MT (e.g., AI, autonomous systems, LLMs)
▪ Guidelines and techniques for the construction of MRs or MT test cases
▪ Prioritization and minimization of MRs or MT test cases
▪ Theoretical analysis and empirical evaluation of MRs or MT test cases (e.g., metrics)
▪ Application of MT and MRs beyond testing
▪ Automation of MT
▪ Formal methods involving MRs
▪ Case studies from practice
▪ Tools
▪ Surveys
▪ Empirical studies
▪ Integration/comparison with other techniques
▪ Novel applications, perspectives, or theories inspired by MT
