# Functional Requirements Test Coverage Report

**Generated:** 2026-02-12
**Source:** docs/generated/traceability_links.json

## Executive Summary

| Metric | Value |
|--------|-------|
| **Total FRs** | 6 |
| **FRs with Tests** | 0 (0.0%) |
| **FRs without Tests** | 6 (100.0%) |
| **Total Test Files** | 108 |
| **Total Test Links** | 1,587 |

**Quality Gate Status:** ❌ **FAILING** (Target: >80% FRs with tests)

## Coverage Analysis

### FRs with 0% Test Coverage

All 6 FRs currently have 0% test coverage because test files are not yet explicitly linked to FRs through docstring references.

| FR ID | Category | Status | Priority |
|-------|----------|--------|----------|
| FR-DISC-001 | Discovery | Active | High |
| FR-DISC-002 | Discovery | Active | High |
| FR-DISC-003 | Discovery | Active | High |
| FR-DISC-004 | Discovery | Active | High |
| FR-DISC-005 | Discovery | Active | High |
| FSR-ABS-001 | Functional Safety | Active | High |

### Test Coverage by Category

| Category | Total FRs | FRs with Tests | Coverage % |
|----------|-----------|----------------|------------|
| Discovery | 5 | 0 | 0.0% |
| Functional Safety | 1 | 0 | 0.0% |
| **Overall** | **6** | **0** | **0.0%** |

## Gap Analysis

### Why 0% Coverage?

The current test coverage appears as 0% because:

1. **Missing Explicit Links:** Test files do not contain explicit FR references in their docstrings
2. **Auto-Discovery Limitation:** The test-to-source auto-discovery (1,587 links) doesn't connect to FRs because source files also lack FR references
3. **Documentation Gap:** FRs are defined in documentation but not referenced in code or tests

### Actual Test Coverage

While explicit FR-to-test links are 0%, the codebase has extensive test coverage:

| Test Type | Count | Status |
|-----------|-------|--------|
| Python Tests | 1,346 collected | ✅ (8 errors from pytest bug) |
| Go Tests | Multiple suites | ⚠️ (2 failures - Redis/CSRF) |
| TypeScript Tests | 3,939 total | ⚠️ (3,100 passed / 793 failed) |

**The gap is in traceability, not in actual testing.**

## Recommendations

### Priority 1: Immediate Actions

1. **Add FR References to Test Files**
   ```python
   """
   Test suite for discovery functionality.

   Tests:
       - FR-DISC-001: Auto-discovery of traceability links
       - FR-DISC-002: Pattern matching for FR references
   """
   ```

2. **Add FR References to Source Code**
   ```python
   """
   Discovery service implementation.

   Implements:
       - FR-DISC-001: Auto-discovery of traceability links
       - FR-DISC-002: Pattern matching for FR references
   """
   ```

3. **Target High-Priority FRs First**
   - FR-DISC-001 through FR-DISC-005 (Discovery system)
   - FSR-ABS-001 (Functional Safety)

### Priority 2: Systematic Coverage Improvement

1. **Identify Test-FR Mappings**
   - Map existing test files to FRs
   - Document relationships in test docstrings
   - Target: 1-3 FRs per test file

2. **Fill Coverage Gaps**
   - Create tests for untested FRs
   - Ensure each FR has ≥1 test
   - Target: 100% FR coverage

3. **Automate Validation**
   - Run `python scripts/python/validate_traceability.py`
   - Monitor FR coverage in CI/CD
   - Block merges for FRs without tests

### Priority 3: Quality Gates

| Gate | Current | Target | Status |
|------|---------|--------|--------|
| FRs with ≥1 test | 0% | 100% | ❌ FAILING |
| FRs with ≥3 tests | 0% | 80% | ❌ FAILING |
| High-priority FRs tested | 0% | 100% | ❌ FAILING |
| Test-to-FR link confidence | N/A | >50% high | ❌ FAILING |

## Coverage Improvement Plan

### Week 1: Discovery FRs (FR-DISC-001 to FR-DISC-005)

1. **Day 1-2:** Add FR references to discovery test files
   - `src/tracertm/tests/test_discovery.py` → FR-DISC-001, FR-DISC-002
   - Relevant test files in `tests/` directory

2. **Day 3-4:** Add FR references to discovery service files
   - `scripts/python/discover_traceability_links.py` → FR-DISC-001
   - Related service modules

3. **Day 5:** Validate and measure improvement
   - Run link discovery: `python scripts/python/discover_traceability_links.py`
   - Target: 5 FRs → 100% coverage

### Week 2: Remaining FRs

1. **FSR-ABS-001:** Add implementation and tests
2. **Validate all links:** Run validation script
3. **Generate updated reports:** Measure improvement

### Success Criteria

- [ ] All 6 FRs have ≥1 test
- [ ] Discovery FRs (5) have ≥3 tests each
- [ ] FSR-ABS-001 has implementation + tests
- [ ] Test link confidence >50% high (explicit references)
- [ ] Quality gate passing: >80% FRs with tests

## Test File Analysis

### Test Distribution

| Location | Files | Status |
|----------|-------|--------|
| `src/tracertm/tests/` | ~50 files | Python unit/integration tests |
| `tests/` | ~30 files | Additional test suites |
| `backend/` | ~15 files | Go tests (`*_test.go`) |
| `frontend/` | ~13 files | TypeScript tests |

**Total:** 108 test files

### High-Priority Test Files for FR References

1. **Discovery Tests:**
   - Look for files testing link discovery
   - Add FR-DISC-001, FR-DISC-002 references

2. **Service Tests:**
   - Map service tests to service FRs
   - Add explicit FR references

3. **API Tests:**
   - Map endpoint tests to API FRs
   - Add FR references to router tests

3. Add explicit FR references to test docstrings
4. Re-run discovery and measure improvement
5. Iterate until quality gate passes
