The article details how Turso, a distributed SQLite implementation, used the Quint formal verification tool to identify over 10 bugs in SQLite itself. A community member modeled SQLite's C API in Quint and ran generated traces against the actual SQLite implementation, uncovering these issues during Turso's hardening process. This demonstrates the value of formal methods in database testing and quality assurance.
Background
SQLite is a widely-used, self-contained, serverless database engine known for its reliability and testing rigor. Turso is building a distributed version of SQLite, requiring even more rigorous testing approaches to ensure reliability at scale.
