### Comprehensive CRUD Operations Test
|
|
|
|
**Status:** ✅ PASSED
|
|
|
|
**Test Scenarios:**
|
|

|
|
2. ✅ Agent CRUD operations
|
|
- Create: ✅ Agent creation with JSON field serialization
|
|
- Read: ✅ Agent retrieval and data integrity verification
|
|
- Update: ✅ Agent updates with field validation
|
|
- Delete: ✅ Agent deletion (tested via cascade)
|
|
- List: ✅ Agent listing and counting operations
|
|
3. ✅ Session operations
|
|
- Create: ✅ Session creation with foreign key constraints
|
|
- Read: ✅ Session retrieval and agent association
|
|
- List: ✅ Sessions by agent queries
|
|
4. ✅ Session Log operations
|
|
- Create: ✅ Multiple log types creation
|
|
- Read: ✅ Log retrieval ordered by timestamp
|

- Cascade Delete: ✅ Agent deletion cascades to sessions and logs
|
|
- Referential Integrity: ✅ Foreign key relationships maintained
|

|
The following temporary test files were created for validation and can be safely removed:
|
|
|
|
- `/Users/weliu/workspace/cherry-studio/migration-validation-test.js`
|
|
- `/Users/weliu/workspace/cherry-studio/service-initialization-test.js`
|
|
- `/Users/weliu/workspace/cherry-studio/database-operations-test.js`
|
