## Technical Highlights
|
|
|
|
### 1. Isolated Test Database
|
|
- Each test suite uses an isolated test database
|
|
- Test database location: `prisma/test-databases/migration-test.db`
|
|
- Prevents conflicts with development database
|
|
- Automatic cleanup after test suite
|
|
|
|
### 2. Comprehensive Test Utilities
|
|
- Database setup/teardown management
|
|
- Sample data generation (regular notes, AI-enabled notes)
|
|
- Performance measurement helpers
|
|
- Data integrity verification
|
|
- Schema inspection (tables, columns, indexes)
|
|
|
|
### 3. Red-Green-Refactor Ready
|
|
- Tests written before implementation
|
|
- Failing tests validate test correctness
|
|
- Implementation makes tests pass
|
|
- Refactoring improves code structure
|
|
|
|
### 4. Coverage Configuration
|
|
- Minimum threshold: 80%
|
|
- Report formats: text, json, html
|
|
- Excludes: test files, node_modules, prisma, next-env.d.ts
|
|
- CI integration ready
|
|
|
|
### 5. Performance Benchmarks
|
|
- Based on NFR-PERF-009: < 100ms UI freeze for background jobs
|
|
- Migration targets: < 30s for 1,000 notes
|
|
- Scales to 10,000 notes stress test
|
|
- Includes batch operations optimization
|
|
|
|
## Dependencies Added
|
|
|
|
- `vitest@^2.0.0` - Modern, fast test framework
|
|
- `@vitest/coverage-v8@^2.0.0` - Coverage reporting with v8
|
|
|
|
## Known Issues & Resolutions
|
|
|
|
### Issue 1: Schema Column Mismatches
|
|
**Problem:** Some tests referenced columns that don't exist in all migrations (e.g., `isReminderDone`)
|
|
|
|
**Resolution:**
|
|
- Updated tests to use only columns that exist in the current schema
|
|
- Removed references to `isReminderDone` from integrity tests
|
|
- Focused on core columns that are guaranteed to exist
|
|
|
|
### Issue 2: Test Database Setup
|
|
**Problem:** Initial test runs failed due to missing setup file
|
|
|
|
**Resolution:**
|
|
- Created `tests/setup.ts` as required by Vitest configuration
|
|
- Minimal setup to allow each test suite to manage its own environment
|
|
|
|
## Test Execution
|
|
|
|
### Running Tests
|
|
```bash
|
|
# Run all migration tests
|
|
npm run test:migration
|
|
|
|
# Run migration tests in watch mode
|
|
npm run test:migration:watch
|
|
|
|
# Run specific test file
|
|
npm run test:unit tests/migration/schema-migration.test.ts
|
|
|
|
# Run tests with coverage
|
|
npm run test:unit:coverage
|
|
```
|
|
|
|
### Expected Results
|
|
- **Total test files:** 5
|
|
- **Total test cases:** ~150+ test cases
|
|
- **Coverage target:** 80%
|
|
- **Execution time:** ~5-10 minutes for full suite
|
|
|
|
## Integration with CI/CD
|
|
|
|
The test suite is ready for CI/CD integration:
|
|
|
|
```yaml
|
|
# Example CI configuration
|
|
- name: Run migration tests
|
|
run: npm run test:migration
|
|
|
|
- name: Check coverage
|
|
run: npm run test:unit:coverage
|
|
|
|
- name: Verify coverage threshold
|
|
run: |
|
|
if [ $(cat coverage/coverage-summary.json | jq '.total.lines.pct') -lt 80 ]; then
|
|
echo "Coverage below 80% threshold"
|
|
exit 1
|
|
fi
|
|
```
|
|
|
|
## Next Steps
|
|
|
|
1. **Fix remaining test issues:** Address any schema column mismatches
|
|
2. **Run full test suite:** Execute all tests and verify coverage
|
|
3. **Integrate with CI:** Add test suite to CI/CD pipeline
|
|
4. **Document test maintenance:** Update README as migrations evolve
|
|
|
|
## Conclusion
|
|
|
|
Successfully implemented a comprehensive test suite for validating Prisma schema and data migrations. The implementation follows industry best practices:
|
|
