Researchers have developed SemaDiff, a novel approach to distinguish between semantic-preserving and semantic-changing commits in software development. This method utilizes behavior-based analysis by comparing test executions on pre- and post-commit versions of code. To ensure consistent testing, SemaDiff generates additional calling methods and tests for the modified code using a large language model, classifying commits as semantic-preserving only if all generated tests yield identical outcomes across versions. In evaluations on open-source Java projects, SemaDiff accurately identified semantic-preserving versus changing commits 76% of the time, achieving 100% precision in detecting semantic-changing commits.
