+# Test Data Generator
+
+## Overview
+
+The Test Data Generator is a comprehensive testing utility that creates realistic submissions to test the moderation queue, versioning, and audit systems. It's accessible from **Admin Settings > Testing** tab.
+
+## Features
+
+- **Multiple Presets**: Small, Medium, Large, and Stress test configurations
+- **Entity Type Selection**: Choose which entities to generate (parks, rides, companies, etc.)
+- **Advanced Options**: Dependencies, conflicts, version chains, escalations
+- **Test Data Marking**: All generated data is marked with `is_test_data: true`
+- **Easy Cleanup**: Clear all test data with one click
+
+## Usage
+
+### Accessing the Generator
+
+1. Log in as a moderator or admin
+2. Navigate to **Admin Settings**
+3. Click the **Testing** tab
+4. Configure your test data generation
+
+### Presets
+
+#### Small (~20 submissions)
+- **Use Case**: Quick sanity checks, basic functionality testing
+- **Contents**: 5 parks, 10 rides, 3 companies, 2 ride models
+- **Time**: ~2-5 seconds
+
+#### Medium (~100 submissions)
+- **Use Case**: Standard testing, queue management validation
+- **Contents**: 20 parks, 50 rides, 20 companies, 10 ride models
+- **Time**: ~10-20 seconds
+
+#### Large (~500 submissions)
+- **Use Case**: Performance testing, pagination verification
+- **Contents**: 100 parks, 250 rides, 100 companies, 50 ride models
+- **Time**: ~45-90 seconds
+
+#### Stress (~2000 submissions)
+- **Use Case**: Load testing, database performance
+- **Contents**: 400 parks, 1000 rides, 400 companies, 200 ride models
+- **Time**: ~3-5 minutes
+
+### Entity Types
+
+Select which entity types to generate:
+
+- **Parks**: Theme parks, amusement parks, water parks
+- **Rides**: Roller coasters, flat rides, water rides, dark rides
+- **Manufacturers**: Companies that build rides
+- **Operators**: Companies that operate parks
+- **Property Owners**: Companies that own park properties
+- **Designers**: Individuals/companies that design rides
+- **Ride Models**: Specific ride model types from manufacturers
+
+### Advanced Options
+
+#### Include Dependencies
+- Creates parent-child relationships (e.g., rides linked to parks)
+- Tests dependency resolution in moderation queue
+- Essential for realistic testing scenarios
+
+#### Include Conflicts
+- Generates submissions with missing dependencies
+- Creates duplicate slug scenarios
+- Tests error handling and conflict resolution
+
+#### Include Version Chains
+- Creates multiple edits on the same entity
+- Tests versioning system and rollback functionality
+- Validates field-level change tracking
+
+#### Include Escalated Items
+- Marks some submissions as high priority
+- Tests escalation workflow
+- Priority queue sorting validation
+
+#### Include Expired Locks
+- Creates submissions with expired moderator locks
+- Tests auto-release mechanism
+- Queue cleanup validation
+
+## Test Data Structure
+
+All test submissions include:
+
+```json
+{
+  "content": {
+    "action": "create",
+    "metadata": {
+      "is_test_data": true,
+      "generated_at": "2024-01-15T10:30:00Z",
+      "generator_version": "1.0.0",
+      "preset": "medium"
+    }
+  }
+}
+```
+
+This metadata allows:
+- Easy identification in database queries
+- Selective cleanup without affecting real data
+- Version tracking of test data generator
+
+## Cleanup
+
+### Clear All Test Data
+
+1. Click **Clear All Test Data** button
+2. Confirm the action in the dialog
+3. All submissions with `is_test_data: true` will be deleted
+4. Process includes:
+   - Deletion of `content_submissions` records
+   - Cascade deletion of related `submission_items`
+   - Cascade deletion of type-specific tables
+   - Removal of photo submissions
+   - Cleanup of version history
+
+**Note**: This only removes test data. Real user submissions are never affected.
+
+## Testing Scenarios
+
+### Basic CRUD Testing
+1. Generate Small preset with all entity types
+2. Navigate to Moderation Queue
+3. Claim and approve a park submission
+4. Verify park appears in database
+5. Clear test data when done
+
+### Dependency Resolution
+1. Generate Medium preset with dependencies enabled
+2. Find a ride submission that depends on a new park
+3. Approve the park first
+4. Verify ride can now be approved
+5. Check that park ID is correctly linked
+
+### Queue Management
+1. Generate Large preset with escalated items
+2. Verify escalated items appear at top of queue
+3. Test claiming and lock expiration
+4. Verify priority sorting works correctly
+
+### Performance Testing
+1. Generate Stress preset
+2. Navigate to moderation queue
+3. Test pagination performance
+4. Test filtering and search performance
+5. Monitor database query times
+
+### Version Chain Testing
+1. Generate Medium preset with version chains
+2. Find an entity with multiple edits
+3. View version history
+4. Test rollback functionality
+5. Verify field-level changes tracked
+
+## Best Practices
+
+### During Development
+- Use **Small** preset for quick iterations
+- Enable only the entity types you're testing
+- Clear test data frequently to avoid clutter
+
+### Before Deployment
+- Run **Medium** preset with all options
+- Verify all workflows complete successfully
+- Test with **Large** preset for performance baseline
+
+### Performance Testing
+- Use **Stress** preset on staging environment
+- Monitor database performance metrics
+- Test concurrent moderator scenarios
+
+### Data Management
+- Clear test data after each testing session
+- Never deploy with test data in production
+- Document any test data used in demos
+
+## Troubleshooting
+
+### Generation Fails
+- Check browser console for errors
+- Verify moderator permissions
+- Check edge function logs in Supabase dashboard
+- Ensure database connection is stable
+
+### Slow Generation
+- Large/Stress presets take time (expected)
+- Check database performance
+- Verify edge function timeout settings
+- Consider generating in smaller batches
+
+### Cannot Clear Test Data
+- Verify test data exists (check stats display)
+- Check RLS policies on content_submissions
+- Ensure cascade delete is configured
+- Check edge function permissions
+
+### Test Data Appears in Production
+- **Never run generator in production**
+- Use separate testing/staging environment
+- If accidentally run, use Clear All Test Data immediately
+- Verify with database query that test data is removed
+
+## Technical Details
+
+### Implementation Files
+- **Service**: `src/lib/testDataGenerator.ts`
+- **UI Component**: `src/components/admin/TestDataGenerator.tsx`
+- **Seed Function**: `supabase/functions/seed-test-data/index.ts`
+- **Integration**: `src/pages/AdminSettings.tsx`
+
+### Database Tables Used
+- `content_submissions` - Main submission records
+- `submission_items` - Individual submission items
+- `park_submissions` - Park-specific data
+- `ride_submissions` - Ride-specific data
+- `company_submissions` - Company-specific data
+- `ride_model_submissions` - Ride model-specific data
+
+### Security
+- Requires moderator role
+- Uses service role key for bulk operations
+- Rate limited to prevent abuse
+- All operations logged in audit trail
+
+## Future Enhancements
+
+Planned features:
+- Photo submission generation
+- Report/moderation flag generation
+- Custom seed configuration
+- Export/import test scenarios
+- Automated test suite integration
+- Performance benchmarking tools
+
+## Support
+
+For issues or questions:
+1. Check edge function logs in Supabase dashboard
+2. Review browser console for client errors
+3. Verify database schema matches expectations
+4. Check RLS policies are correctly configured
