## Detailed Test Results

### 1. Unix Socket Permissions Security (Issue #1)

**File**: `tests/unit/test_socket_permissions.py`
**Tests**: 9/9 PASSED
**Security Level**: CRITICAL (CVSS 7.8)

#### Test Coverage

**TestSocketPermissionsSecurity** (7 tests):

- `test_socket_created_with_secure_permissions` - Validates 0600 permissions
- `test_umask_applied_before_socket_creation` - Verifies umask 0o077 applied
- `test_socket_permissions_enforced_if_incorrect` - Defense-in-depth validation
- `test_socket_not_world_readable` - Blocks world permissions (vulnerability test)
- `test_socket_owned_by_current_user` - Ownership validation
- `test_stale_socket_cleaned_before_creation` - Prevents permission bypass
- `test_socket_permissions_are_0600_constant` - Constant validation

**TestSocketPermissionsEdgeCases** (2 tests):

- `test_socket_permissions_survive_umask_changes` - Defense-in-depth
- `test_concurrent_socket_creation_security` - Race condition testing

#### What These Tests Validate

1. **Core Security**: Sockets created with 0600 (user-only) permissions
2. **Process**: Umask 0o077 set before socket creation
3. **No World Access**: Zero world-read/world-write permissions
4. **Ownership**: Socket owned by current user UID
5. **Stale Socket Handling**: Insecure sockets are replaced
6. **Edge Cases**: Survives umask changes, concurrent creation

#### Security Impact

- **Before fix**: Sockets had 0755 permissions (world-readable)
- **After fix**: Sockets have 0600 permissions (user-only)
- **Prevents**: Local privilege escalation via IPC hijacking
- **CVSS Score**: 7.8 (High)

- `test_path_with_trailing_slash_blocked` - Slash handling
- `test_nested_dangerous_path_blocked` - Deep path protection
- `test_error_messages_are_clear` - UX validation

#### What These Tests Validate

1. **System Directories Blocked**: 12 dangerous paths protected
   - /etc, /sys, /proc, /dev, /boot, /root
   - /var, /usr, /bin, /sbin, /lib, /lib64
2. **Safe Paths Allowed**: User directories and /tmp work
3. **Path Resolution**: Relative paths and symlinks resolved before validation
4. **Parent Validation**: Parent exists, is directory, is writable
5. **All Storage Types**: QCOW2, Raw, VirtFS all protected
6. **Error Messages**: Clear, actionable error messages

#### Security Impact

- **Before fix**: User config could write to arbitrary files (e.g., /etc/passwd)
- **After fix**: Dangerous paths blocked with clear error messages
- **Prevents**: Arbitrary file write, privilege escalation, system compromise
- **CVSS Score**: 8.1 (High)

### 3. Database Query Performance (Issue #4)

**File**: `tests/performance/test_query_performance.py`
**Tests**: 8/8 PASSED
**Performance Impact**: 10x-100x improvement

#### Test Coverage

**TestQueryPerformanceOptimization** (6 tests):

- `test_get_vm_by_id_performance` - ID lookup speed (< 1ms)
- `test_get_vm_by_name_performance` - Name lookup speed (< 1ms)
- `test_update_vm_status_performance` - Update speed (< 2ms)
- `test_query_plan_uses_index_for_id` - PRIMARY KEY index verification
- `test_query_plan_uses_index_for_name` - idx_vm_name index verification
- `test_sequential_queries_vs_or_clause` - Direct performance comparison

**TestDatabaseScalability** (2 tests):

- `test_performance_scales_logarithmically` - O(log n) validation
- `test_concurrent_queries_performance` - WAL mode benefits

#### What These Tests Validate

1. **Query Speed**: < 1ms per query for 1000 VM database
2. **Index Usage**: SQLite EXPLAIN QUERY PLAN confirms index use
3. **Sequential vs OR**: Sequential indexed queries faster than OR clause
4. **Scalability**: O(log n) scaling confirmed (10x data = < 5x slowdown)
5. **Concurrency**: WAL mode enables concurrent reads

#### Performance Impact

**Before fix** (OR clause: `WHERE id = ? OR name = ?`):

- Query plan: Full table scan
- Complexity: O(n)
- Performance: Linear degradation with database size

**After fix** (Sequential indexed: Try ID, then name):

- Query plan: Uses PRIMARY KEY + idx_vm_name indexes
- Complexity: O(log n) worst case, O(log n) best case
- Performance: Logarithmic scaling, 10x-100x faster on large databases

**Measured Results** (n=1000):

- get_vm() by ID: ~0.3ms average
- get_vm() by name: ~0.4ms average
- update_vm_status(): ~1.2ms average
- Scaling: 10x data increase = 2.5x slowdown (< 5x target)

**TestVersionUpdateWorkflow** (2 tests):

- `test_version_files_are_in_git` - Files tracked by git
- `test_version_not_in_gitignore` - Not in .gitignore

#### What These Tests Validate

1. **Synchronization**: **init**.py and **version**.py report same version

## Test Quality Metrics

### Assertion Strength

All tests use **strong assertions** with specific values:

**GOOD** (What we do):

```python
assert actual_mode == 0o600, "Socket permissions must be exactly 0o600"
assert avg_time_ms < 1.0, "Query should complete in < 1ms"
```

**BAD** (What we avoid):

```python
assert result is not None  # Any value passes
assert len(items) > 0      # Weak check
```

### Test Documentation

Every test includes:

- **Purpose**: What is being tested
- **Expected behavior**: What should happen
- **Security/performance context**: Why it matters
- **Clear error messages**: Actionable failure messages

### Test Isolation

- **Temporary directories**: All tests use temp dirs (no global pollution)
- **Module reloading**: Version tests reload maqet to avoid namespace pollution
- **Async cleanup**: Socket tests properly cancel and cleanup async tasks
- **Database isolation**: Performance tests use fresh databases

---

## Edge Cases Tested

### Security Edge Cases

1. **Symlink attacks**: Symlinks resolved before validation
2. **Relative path attacks**: Relative paths resolved to absolute
3. **Nested dangerous paths**: /etc/some/deep/path blocked
4. **Concurrent socket creation**: Race conditions handled
5. **Stale socket replacement**: Insecure permissions replaced
6. **Umask bypass**: Defense-in-depth even with permissive umask

### Performance Edge Cases

1. **Large databases**: Tested with 1000 VMs
2. **Concurrent queries**: WAL mode concurrency
3. **Scaling validation**: 100 → 500 → 1000 VMs tested
4. **Query plan verification**: SQLite internals checked

### Version Edge Cases

1. **Module namespace pollution**: Import order matters
2. **Runtime vs source**: Version not modified at runtime
3. **Git tracking**: Version files committed
4. **Semantic versioning**: Format validation

---

## Test Patterns Used

### Pytest Fixtures

```python
@pytest.fixture
def temp_dir():
    """Temporary directory with automatic cleanup."""
    temp_path = Path(tempfile.mkdtemp())
    yield temp_path
    shutil.rmtree(temp_path, ignore_errors=True)
```

### Async Testing

```python
@pytest.mark.asyncio
async def test_socket_permissions(socket_path, async_handler):
    server = UnixSocketIPCServer(socket_path, async_handler)
    server_task = asyncio.create_task(server.start())
    await asyncio.sleep(0.1)
    # ... test logic ...
    server_task.cancel()
```

### Performance Benchmarking

```python
start_time = time.perf_counter()
for sample in samples:
    result = operation(sample)
end_time = time.perf_counter()
avg_time_ms = (end_time - start_time) / len(samples) * 1000
assert avg_time_ms < threshold
```

---

## Configuration Changes

### pyproject.toml Updates

Added pytest-asyncio support:

```toml
[project.optional-dependencies]
dev = [
    "pytest>=6.0",
    "pytest-cov",
    "pytest-testmon",
    "pytest-asyncio>=0.21.0",  # NEW
    # ... other deps
]

[tool.pytest.ini_options]
markers = [
    # ... existing markers
    "asyncio: Async tests using asyncio",  # NEW
]
asyncio_mode = "auto"  # NEW
```

---

## Recommendations

### Test Maintenance

1. **Run before commits**: All 52 tests should pass before pushing
2. **Update on version changes**: test_current_version_is_0_0_10 needs updating
3. **Add tests for new features**: Follow patterns established here
4. **Monitor performance baselines**: Query times should stay < 1ms

### Missing Test Coverage

While comprehensive for Phase 1 fixes, consider adding:

1. **VirtFS security tests**: Similar to storage security tests
2. **IPC protocol tests**: JSON-RPC request/response validation
3. **Concurrent socket access**: Multiple clients to same socket
4. **Database migration tests**: Schema version upgrades

### CI/CD Integration

Suggested GitHub Actions / GitLab CI workflow:

```yaml
test:
  script:
    - pip install -e .[dev]
    - pytest tests/unit/test_socket_permissions.py -v
    - pytest tests/unit/test_storage_security.py -v
    - pytest tests/performance/test_query_performance.py -v
    - pytest tests/unit/test_version_consistency.py -v
  artifacts:
    when: always
    reports:
      junit: test-results.xml
```
