## Testing Priorities
|
|
|
|
### High Priority (Block Progress)
|
|
1. Delta validation tests
|
|
2. Transaction support tests
|
|
3. Basic schema validation tests
|
|
4. Negation handling tests
|
|
|
|
### Medium Priority (Needed for Features)
|
|
1. Advanced resolver tests
|
|
2. Nested object tests
|
|
3. Query engine tests
|
|
4. Relational constraint tests
|
|
|
|
### Low Priority (Nice to Have)
|
|
1. Performance benchmarks
|
|
2. Network resilience tests
|
|
3. Large-scale integration tests
|
|
|
|
## Implementation Order
|
|
|
|
1. **Start with Phase 1** - These are foundational requirements
|
|
2. **Phase 2.1 (Negation)** - Core spec feature that affects all views
|
|
3. **Phase 2.2 (Resolvers)** - Needed for proper lossy views
|
|
4. **Phase 3 (Query)** - Unlocks powerful data access
|
|
5. **Phase 2.3 (Nesting)** - Depends on schemas and queries
|
|
6. **Phase 4 (Relational)** - Builds on query system
|
|
7. **Phase 5 & 6** - Optimization and polish
|
|
|
|
## Notes
|
|
|
|
- Each phase should include comprehensive tests before moving to the next
|
|
- Schema design in Phase 1.3 will impact many subsequent phases
|
|
- Query system (Phase 3) may reveal needs for index structures
|
|
- Consider creating integration tests that span multiple phases |
