Dinkel: State-Aware and Granular Framework for Validating Graph Databases
Summary: Dinkel generates deep, valid Cypher by tracking query context and graph schema while evolving graph state clause by clause. Clause- and expression-level semantics-preserving transformations provide general oracles, exposing 127 bugs across three GDBMSs. (summarized by gpt-5.6-luna on Jul 24 2026)
