- **Integration Tests**:
- Introduced `api-integration.test.ts` to validate API functionality:
- Verifies text insertion, vector embedding generation, and search operations.
- Confirms HNSW index correctness for vector similarity search.
- Ensures no dimensional mismatches in embeddings.
- **Test Server**:
- Added test server utilizing Express for endpoint simulation (`/insert` and `/search/text`).
- **Dependencies**:
- Introduced `express` and `node-fetch` as new dependencies for testing purposes.
- **Vitest Fix**:
- Updated `vitest.config.ts` to resolve the `process.memoryUsage` error by setting `logHeapUsage: false`.
- **Package Updates**:
- Modified `package-lock.json` to include newly added dependencies and updates.
**Purpose**: Guarantees the stability of core API endpoints and vector-related functionality, ensuring reliable behavior for end-to-end scenarios.
- Introduced comprehensive mock for the Origin Private File System (OPFS) in `tests/mocks/opfs-mock.ts`, simulating environment for detailed storage testing.
- Added `tests/opfs-storage.test.ts`, containing extensive test cases for `OPFSStorage` operations including metadata, nouns, verbs, and storage status.
- Improved S3 mock implementation in `tests/mocks/s3-mock.ts` with better object persistence, validation, and logging to emulate real S3 behavior.
- Resolved issues related to metadata, nouns, verbs, and storage usage inconsistencies in mock storage adapters.
- Enhanced logging and error handling to aid in debugging and test reliability.
Purpose: Improve test completeness and reliability by introducing detailed mocks and extended test cases for S3 and OPFS storage systems.
