| | Query Plan Guidance (QPG) | QPG is a test case generation method guided by query plan coverage. Given a database state, we mutate it when no new unique query plan has been covered by the random generated queries on the database state aiming to cover more unqiue query plans for exposing more logics of DBMSs. This approach is enabled by option `--qpg-enable` and now supports TLP and NoREC oracles for SQLite, CockroachDB, and TiDB. | |
