HOW SQLITE IS TESTED

Summary from the TLDR Dev newsletter

SQLite has a thorough and multi-faceted testing process, with test code outweighing its core library. This includes four independent test harnesses that collectively run billions of test cases to verify functionality, cross-database compatibility, and resilience to malicious inputs. Specialized anomaly tests simulate and verify proper handling of out-of-memory conditions, I/O errors, and power loss.
