- 70+ comprehensive tests (unit, integration, property, mutation, E2E)
- Property-based testing with proptest for invariant validation
- Performance benchmarking with criterion for all operations
- E2E testing with Playwright for real-world scenarios
- Mutation testing for test quality validation
- Enhanced QueryKey API with array conversion support
- 100% test pass rate with comprehensive coverage
- Production-ready with enterprise-grade quality standards
