SQLancer is a Java-based automated testing tool that finds logic and performance bugs in database management systems. It generates SQL test inputs and applies test oracles such as Ternary Logic Partitioning, NoREC, and Pivoted Query Synthesis to detect incorrect results, crashes, and performance issues.
Use cases
- find logic bugs in a database system
- fuzz test sqlite mysql postgresql
- detect incorrect query results in a dbms
- find performance bugs in query optimizers
- automated testing of cockroachdb or tidb
- discover crash bugs in database implementations
When to choose
- you develop or maintain a DBMS and want automated bug finding
- you want to validate query correctness with published test oracles
- you need to stress-test SQL implementations across many database engines
When to avoid
- you want to test your own SQL queries rather than the DBMS itself
- you need functional/load testing of an application's database usage
- you need a general-purpose web or API fuzzer
