## 📋 TEST COVERAGE ANALYSIS
|
||
|
||
### Coverage Metrics (From npm test)
|
||
```
|
||
Lines: 65.3% │ ██████░░░░░░░░░ │ ACCEPTABLE
|
||
Branches: 58.2% │ █████░░░░░░░░░░ │ NEEDS WORK
|
||
Functions: 72.5% │ ███████░░░░░░░░ │ GOOD
|
||
Statements: 66.8% │ ██████░░░░░░░░░ │ ACCEPTABLE
|
||
```
|
||
|
||
### Coverage Gaps (Top Priorities)
|
||
|
||
1. **Quality Validator Module: 0% coverage** ⚠️ CRITICAL
|
||
- Location: `src/lib/quality-validator/`
|
||
- Impact: 5,000+ lines untested
|
||
- **Fix:** Implement 100+ test cases (see test files in `tests/unit/quality-validator/`)
|
||
|
||
2. **Pyodide Runner: 9.7% coverage** ⚠️ CRITICAL
|
||
- Location: `src/lib/pyodide-runner.ts`
|
||
- Lines: 1-42, 45-93, 102-223
|
||
- **Fix:** Add integration tests for Python execution
|
||
|
||
3. **IndexedDB Storage: 25.31% coverage** ⚠️ CRITICAL
|
||
- Location: `src/lib/indexeddb-storage.ts`
|
||
- **Fix:** Add database operation tests
|
||
|
||
4. **Storage Utility: 75.75% coverage** ⚠️ MEDIUM
|
||
- Location: `src/lib/storage.ts`
|
||
- **Fix:** Cover error cases and edge cases
|
||
|
||
5. **Middleware: 70.41% coverage** ⚠️ MEDIUM
|
||
- Location: `src/store/middleware/`
|
||
- **Fix:** Test persistence configuration
|
||
|
||
### Test Effectiveness
|
||
- **Assertion Density:** Good (multiple assertions per test)
|
||
- **Mocking:** Excellent (proper mocking for external dependencies)
|
||
- **Isolation:** Good (tests properly isolated)
|
||
- **Edge Cases:** Moderate (could add more boundary testing)
