• Automated test generation: search-based and evolutionary test data generation, coverage-guided fuzzing, symbolic and concolic test generation, model-based test derivation, mutation-driven test generation, and generation of tests for concurrent and non-deterministic systems.
• Software testing methods and levels: unit, integration, and system testing strategies, regression test selection and prioritisation, combinatorial and pairwise interaction testing, user-session and usage-based testing, testing of web, mobile, and distributed applications, and testing of machine learning and data-driven systems.
• Test optimisation and adequacy: test suite minimisation and reduction, coverage criteria and their effectiveness, mutation analysis and mutation score, test oracle design and the oracle problem, flaky test detection, and cost–benefit analysis of testing strategies.
• Defect prediction and software quality modelling: fault-proneness prediction using computational intelligence, software metrics and feature selection for quality models, imbalanced data handling in defect datasets, cross-project and cross-version prediction, dataset quality and provenance, and reliability growth modelling.
• Verification, validation, and fault diagnosis: model checking and formal verification, runtime verification and monitoring, automated fault localisation and program repair, anomaly detection in software behaviour, and combined analytical and intelligent approaches to assurance.
• Applications of soft computing: optimisation in engineering design and scheduling, pattern recognition and classification tasks, forecasting and time series modelling, resource allocation in computing systems, and decision support in complex and uncertain domains.
