## 🔍 Detailed Test Gap Analysis

### 1. Core ConflictDetector Tests (✅ EXCELLENT)

**Existing Coverage** (18 tests):
- ✅ File overlap detection (basic, multiple, no overlap)
- ✅ Risk scoring (high, medium, low, edge cases)
- ✅ Safe order recommendation (with/without dependencies)
- ✅ File conflict checking
- ✅ Error handling (task not found, empty files)
- ✅ Pydantic validation

**Identified Gaps** (3 missing tests):

#### Gap 1.1: Circular Dependency in recommend_safe_order
**Severity**: 🟡 Medium
**Missing Test**:
```python
def test_recommend_safe_order_circular_dependency():
    """Test that circular dependencies are detected and handled."""
    # TASK-001 depends on TASK-002
    # TASK-002 depends on TASK-001
    # Should raise CircularDependencyError or return partial order
```
**Risk**: Users might create circular dependencies
**Impact**: Low (TaskManager already validates, but defense-in-depth)

#### Gap 1.2: Large Task Set Performance
**Severity**: 🟢 Low
**Missing Test**:
```python
def test_detect_conflicts_performance_50_tasks():
    """Test performance with 50 tasks (real-world scenario)."""
    # Create 50 tasks
    # Measure time < 2 seconds
    # Verify correctness
```
**Risk**: Performance degradation not caught early
**Impact**: Low (manual testing done, but not automated)

#### Gap 1.3: Same File, Different Sections (Future)
**Severity**: 🟢 Low (Phase 3 feature)
**Missing Test**:
```python
def test_detect_conflicts_same_file_different_sections():
    """Test that line-level analysis reduces false positives."""
    # TASK-001 edits lines 1-50
    # TASK-002 edits lines 100-150
    # Risk should be LOW, not HIGH
```
**Risk**: False positives in current version
**Impact**: Low (documented limitation, Phase 3 enhancement)

---

### 2. CLI Commands Tests (✅ EXCELLENT)

**Existing Coverage** (21 tests):
- ✅ All 3 commands (detect, order, check)
- ✅ Success paths
- ✅ Error paths (task not found, empty list)
- ✅ Verbose mode
- ✅ Details mode
- ✅ Multiple files/tasks
- ✅ Edge cases (empty files, special characters, completed tasks)
- ✅ Help output

**Identified Gaps** (2 missing tests):

#### Gap 2.1: Output Format Regression Test
**Severity**: 🟡 Medium
**Missing Test**:
```python
def test_conflict_detect_output_format_stable():
    """Test that output format remains stable for parsing."""
    # Ensure output contains:
    # - "Conflict Detection Report"
    # - "Risk: HIGH|MEDIUM|LOW"
    # - "→" for recommendations
    # Prevents accidental UI changes breaking scripts
```
**Risk**: CLI output changes break user scripts
**Impact**: Medium (users may parse output)

#### Gap 2.2: Color Output Test
**Severity**: 🟢 Low
**Missing Test**:
```python
def test_conflict_detect_color_output():
    """Test that color codes are correctly applied."""
    # High risk: red
    # Medium risk: yellow
    # Low risk: blue
    # Verify Click color rendering
```
**Risk**: Color coding inconsistency
**Impact**: Low (cosmetic, manual verification done)

---

### 3. MCP Tools Tests (🟡 NEEDS VERIFICATION)

**Current Status**:
- MCP server tests exist in `tests/mcp/test_server.py`
- Grep shows 14 conflict-related tests (estimated)
- **No explicit grep matches** for conflict tool tests

**Verification Needed**:
```bash
# Need to verify:
grep -n "detect_conflicts\|recommend_safe_order\|check_file_conflicts" \
  tests/mcp/test_server.py
```

**Identified Gaps** (3 missing tests):

#### Gap 3.1: MCP Tool Input Validation
**Severity**: 🟡 Medium
**Missing Test**:
```python
@pytest.mark.asyncio
async def test_detect_conflicts_tool_invalid_input():
    """Test MCP tool validates input correctly."""
    # Missing task_id
    # Invalid task_id format
    # Should return error response
```
**Risk**: MCP tool crashes on bad input
**Impact**: Medium (Claude Code sends unexpected data)

#### Gap 3.2: MCP Tool Output Format
**Severity**: 🟡 Medium
**Missing Test**:
```python
@pytest.mark.asyncio
async def test_detect_conflicts_tool_output_schema():
    """Test MCP tool output matches schema."""
    # Verify JSON structure
    # Ensure all required fields present
    # Validate types
```
**Risk**: Claude Code cannot parse response
**Impact**: Medium (integration breakage)

#### Gap 3.3: MCP Tool Error Handling
**Severity**: 🟡 Medium
**Missing Test**:
```python
@pytest.mark.asyncio
async def test_mcp_tools_handle_task_manager_errors():
    """Test MCP tools handle TaskManager errors gracefully."""
    # Mock TaskManager.get() to raise NotFoundError
    # Verify MCP returns user-friendly error
```
**Risk**: Unhelpful error messages in Claude Code
**Impact**: Medium (user experience)

---

### 4. Integration Tests (🔴 CRITICAL GAP)

**Current Status**:
- **File `tests/integration/test_conflict_workflows.py` does NOT exist**
- No end-to-end workflow tests found
- Integration testing claimed but not verified

**Severity**: 🔴 High
**Impact**: High (no full workflow validation)

**Missing Test File**: `tests/integration/test_conflict_workflows.py`

**Required Tests** (5 workflows):

#### Test 4.1: Pre-Start Check Workflow
```python
def test_workflow_pre_start_check(tmp_path):
    """
    Test complete pre-start check workflow.

    1. Create 2 in_progress tasks with overlapping files
    2. Add new task with same files
    3. Run: clauxton conflict detect TASK-003
    4. Verify: Conflict detected, recommendation shown
    5. Run: clauxton conflict order TASK-001 TASK-002 TASK-003
    6. Verify: Safe order returned
    """
```

#### Test 4.2: Sprint Planning Workflow
```python
def test_workflow_sprint_planning(tmp_path):
    """
    Test sprint planning workflow.

    1. Create 10 tasks with various priorities and file overlaps
    2. Run: clauxton conflict order TASK-*
    3. Verify: Order respects priorities and minimizes conflicts
    4. Simulate starting tasks in order
    5. Verify: No conflicts occur
    """
```

#### Test 4.3: File Coordination Workflow
```python
def test_workflow_file_coordination(tmp_path):
    """
    Test file coordination workflow.

    1. Start TASK-001 (in_progress, edits file.py)
    2. Run: clauxton conflict check file.py
    3. Verify: File locked by TASK-001
    4. Complete TASK-001
    5. Run: clauxton conflict check file.py
    6. Verify: File available
    """
```

#### Test 4.4: MCP-CLI Integration
```python
@pytest.mark.asyncio
async def test_workflow_mcp_cli_consistency(tmp_path):
    """
    Test MCP and CLI produce consistent results.

    1. Create test scenario
    2. Call MCP detect_conflicts tool
    3. Call CLI: clauxton conflict detect
    4. Verify: Both return same conflicts
    """
```

#### Test 4.5: Error Recovery Workflow
```python
def test_workflow_error_recovery(tmp_path):
    """
    Test error handling across components.

    1. Corrupt tasks.yml
    2. Run: clauxton conflict detect TASK-001
    3. Verify: Clear error message
    4. Restore tasks.yml from backup
    5. Run: clauxton conflict detect TASK-001
    6. Verify: Works correctly
    """
```
