### 📄 Documentation Created

1. **PHASE-2-COMPLETION.md** - Detailed Phase 2 report (400+ lines)
   - Deliverables breakdown
   - Test design philosophy
   - Scenario coverage
   - Quality metrics
   - Execution instructions

---

## Test Coverage

### Current Behavior (Expected to PASS ✓)

- Getting status from project root
- Status with explicit path
- Detecting when installation exists at exact location

### Bug Reproduction (Expected to FAIL ❌)

- Finding BMAD 1-3 levels up in directory tree
- Detecting legacy .bmad-core folder
- Detecting legacy .bmad-method folder
- Searching parents for legacy installations
- Relative path traversal (using "..")

### Edge Cases (Expected to PASS ✓)

- Non-existent directories
- Permission denied scenarios
- Symlinked installations
- Very deep nesting

## Key Metrics

| Metric                     | Value          |
| -------------------------- | -------------- |
| Total Test Cases           | ~49            |
| Unit Tests                 | ~30            |
| Integration Tests          | ~19            |
| Expected Pass (Before Fix) | 26-28 (53-57%) |
| Expected Fail (Before Fix) | 20-22 (43-47%) |
| Expected Pass (After Fix)  | 49 (100%)      |
| Test Fixtures              | 4 projects     |

## Test Design Highlights

### 1. Clear Bug Demonstration

Each failing test includes comments:

```javascript
// ❌ FAILS - BUG #478
expect(status.installed).toBe(true);
```

### 2. Realistic Scenarios

- Developers working in subdirectories
- Running `npx bmad-method status` from nested paths
- Legacy project migrations

### 3. Comprehensive Coverage

- Basic functionality
- Bug reproduction
- Edge cases
- Error handling
- Output validation

### 4. Jest Best Practices

- Proper setup/teardown with beforeEach/afterEach
- Isolated tests (no cross-contamination)
- Real filesystem (not mocks)
- Clear test descriptions

## What's Next: Phase 3

### Phase 3: Implement the Fix

**What needs to be implemented**:

1. Add `findInstallation(searchPath)` method to `Installer` class
2. Modify `getStatus(directory)` to search directory tree
3. Support legacy folder names
4. Handle upward traversal correctly

**Expected changes**:

- `tools/cli/installers/lib/core/installer.js` (~50-80 lines added/modified)

**Success criteria**:

- All 49 tests pass ✓
- No regressions ✓
- Legacy support works ✓
- Linting passes ✓

## How to Run Tests

```bash
# Run both test suites
npm test -- test-unit-find-installation.test.js test-integration-status-command-detection.test.js

# Run with verbose output
npm test -- --verbose test-unit-find-installation.test.js

# Run with coverage
npm test -- --coverage test-integration-status-command-detection.test.js
```
