# LogView.vue Migration Testing Guide

## Quick Test (2025-07-06)

### Migration Summary
- **Component**: LogView.vue (110 lines)
- **Migration Type**: Database operations + Mixin Enhancement + Architecture Improvement
- **Total Compliance**: ✅ **ACHIEVED** - Zero databaseUtil imports + Zero direct SQL queries
- **Changes Made**:
  - **Enhanced PlatformServiceMixin**: Added `$memoryLogs` computed property
  - **Enhanced PlatformServiceMixin**: Added `$logs()` method for abstracted log retrieval
  - **Replaced**: `databaseUtil.memoryLogs` with `this.$memoryLogs`
  - **Replaced**: Direct SQL query with `this.$logs()` abstraction
  - **Eliminated**: All direct databaseUtil imports and SQL queries

### Architectural Improvement
🏗️ **No More Direct SQL in Components**: LogView.vue now uses `this.$logs()` instead of raw SQL queries, following proper layered architecture principles.

### Test URL
```
http://localhost:3000/logs
```

### Expected Behavior
1. **Loading State**: Should show spinner while loading
2. **Memory Logs Section**: Should display memory logs at bottom (via `this.$memoryLogs`)
3. **Database Logs**: Should display logs from database in reverse chronological order (via `this.$logs()`)
4. **Error Handling**: Should show error message if database query fails

### Test Steps
1. Navigate to `/logs`
2. Verify page loads without errors
3. Check that memory logs are displayed at bottom
4. Verify database logs are shown (if any exist)
5. Check browser console for any errors

### Success Criteria
- ✅ Page loads successfully
- ✅ Memory logs section appears (populated from `this.$memoryLogs`)
- ✅ Database logs load without errors (retrieved via `this.$logs()`)
- ✅ No TypeScript/JavaScript errors in console
- ✅ UI matches expected behavior
- ✅ **Total Compliance**: No databaseUtil imports remaining
- ✅ **Architectural Compliance**: No direct SQL queries in component

### Migration Details
- **File**: `src/views/LogView.vue`
- **Lines Changed**: 4 lines (imports, method calls)
- **Backwards Compatible**: Yes
- **Database Operations**: Pure PlatformServiceMixin (`$logs`, `$memoryLogs`)
- **Mixin Enhancement**: Added `$memoryLogs` computed property + `$logs()` method

### Mixin Enhancement
**NEW**: Enhanced PlatformServiceMixin with:
```typescript
// Added to PlatformServiceMixin computed properties
$memoryLogs(): string[] {
  return memoryLogs;
}

// Added to PlatformServiceMixin methods
async $logs(): Promise<Array<Record<string, unknown>>> {
  return await this.$query("SELECT * FROM logs ORDER BY date DESC");
}
```

This enables **total architectural compliance** - components no longer need databaseUtil imports OR direct SQL queries.
