differential-fuzzer
Property-based fuzzer that compares Turso against SQLite to catch SQL correctness bugs.
Works with
What it does
Generates random SQL statements and schemas, then executes them on both Turso and SQLite to detect mismatches in row sets, error handling, or schema state
Supports deterministic reproduction via seed-based runs, configurable statement/table/column counts, and verbose output for debugging
Includes continuous loop mode for extended fuzzing campaigns and Docker runner for CI with configurable timeout
