Migrating them across frameworks is a behavior-preserving refactoring spanning build configuration, dependency injection, persistence, request handling, and deployment. Existing software-engineering benchmarks cover bug fixing, feature implementation, and language or version modernization, but leave cross-framework refactoring largely unmeasured.\n  We introduce ScarfBench, a benchmark for behavior-preserving cross-framework refactoring of enterprise Java applications.
