+## Running Tests
+
+### Local Development
+```bash
+# Run all unit tests
+npm run test:unit
+
+# Watch mode for development
+npm run test:unit:watch
+
+# Interactive UI
+npm run test:unit:ui
+
+# Coverage report
+npm run test:unit:coverage
+
+# Run all tests (unit + e2e)
+npm run test:all
+```
+
+### CI/CD Pipeline
+Unit tests automatically run on:
+- Push to main/master/develop branches
+- Pull requests
+- After linting, before build
+
+## Test Statistics
+
+- **Total Test Files**: 13
+- **Package Test Files**: 12 (2 per package × 6 packages)
+- **Integration Test Files**: 1
+- **Total Packages Tested**: 6
+- **Documentation Files**: 8 (6 package READMEs + 1 integration README + 1 main doc)
+
+## Benefits
+
+1. **Quality Assurance**: Validates package structure and metadata
+2. **Early Detection**: Catches configuration errors before deployment
+3. **Documentation**: Tests serve as living documentation
+4. **CI/CD Integration**: Automated validation on every PR
+5. **Developer Experience**: Quick feedback during development
+6. **Maintainability**: Easier to refactor with test coverage
+7. **Confidence**: Ensures package system integrity
+
+## Next Steps
+
+Potential enhancements:
+- [ ] Add Lua script validation tests
+- [ ] Add workflow definition tests
+- [ ] Add schema validation tests
+- [ ] Add component rendering tests
+- [ ] Add API endpoint tests
+- [ ] Increase coverage thresholds
+- [ ] Add snapshot testing
+- [ ] Add performance benchmarks
+
+## Conclusion
+
+The MetaBuilder platform now has comprehensive unit test coverage for all packages, ensuring package metadata integrity, component structure validation, and system-wide consistency. The tests are integrated into the CI/CD pipeline and provide immediate feedback to developers.

+# Package Unit Tests Documentation
+
+This document describes the unit testing structure for all packages in the MetaBuilder platform.
+
+## Overview
+
+Each package in the `/packages` directory has its own `tests/` folder containing unit tests that validate:
+- Package metadata structure
+- Component definitions
+- Configuration validation
+- Data integrity
+
+## Test Structure
+
+```

+        ├── README.md
+        ├── metadata.test.ts
+        └── components.test.ts
+```
+
+## Running Tests
+
+### Run all unit tests
+```bash
+npm run test:unit
+```
+
+### Run tests in watch mode
+```bash
+npm run test:unit:watch
+```
+
+### Run tests with UI
+```bash
+npm run test:unit:ui
+```
+
+### Run tests with coverage
+```bash
+npm run test:unit:coverage
+```
+
+### Run all tests (unit + e2e)
+```bash
+npm run test:all
+```
+
+## Test Coverage
+
+### Metadata Tests
+Each package includes `metadata.test.ts` that validates:
+- Package ID format (lowercase with underscores)
+- Semantic versioning format
+- Required metadata fields
+- Export configurations
+- Dependency declarations
+
+### Component Tests
+Each package includes `components.test.ts` that validates:
+- Component array structure
+- Component ID and type fields
+- Data integrity
+
+## Testing Framework
+
+- **Framework**: Vitest
+- **Environment**: jsdom
+- **Configuration**: `vitest.config.ts`
+
+## CI/CD Integration
+
+Unit tests are automatically run in the CI/CD pipeline on:
+- Pull requests
+- Push to main branch
+- Manual workflow dispatch
+
+## Adding New Tests
+
+When creating a new package:
+
+1. Create a `tests/` directory in the package folder
+2. Add `metadata.test.ts` for metadata validation
+3. Add `components.test.ts` for component validation
+4. Add `README.md` documenting the tests
+5. Follow the existing test patterns
+
+### Example Test Template
+
+```typescript
+import { describe, it, expect } from 'vitest'
+import metadata from '../seed/metadata.json'
+
+describe('Package Name Metadata', () => {
+  it('should have valid package structure', () => {
+    expect(metadata.packageId).toBe('package_id')
+    expect(metadata.name).toBeDefined()
+    expect(metadata.version).toBeDefined()
+  })
+
+  it('should have semantic version', () => {
+    expect(metadata.version).toMatch(/^\d+\.\d+\.\d+$/)
+  })
+})
+```
+
+## Best Practices
+
+1. **Keep tests focused**: Each test should validate one specific aspect
+2. **Use descriptive names**: Test names should clearly state what is being tested
+3. **Follow AAA pattern**: Arrange, Act, Assert
+4. **Test edge cases**: Include tests for boundary conditions and error states
+5. **Maintain independence**: Tests should not depend on execution order
+
+## Troubleshooting
+
+### Tests not found
+Ensure the test file pattern matches `**/*.test.ts` or `**/*.test.tsx`
+
+### Import errors
+Check that the relative paths to seed data are correct
+
+### Configuration issues
+Verify `vitest.config.ts` includes the correct test paths
+
+## Future Enhancements
+
+- [ ] Add integration tests for package loading
+- [ ] Add snapshot tests for component rendering
+- [ ] Add performance benchmarks
+- [ ] Add mutation testing
+- [ ] Add visual regression tests

+# Source Unit Tests
+
+This directory contains integration tests for the MetaBuilder platform.
+
+## Test Files
+
+- `package-integration.test.ts` - Tests package system integration and validation
+
+## Package Integration Tests
+
+The integration tests validate:
+- Unique package IDs across all packages
+- Semantic versioning compliance
+- Complete metadata for all packages
+- Valid category assignments
+- Export configurations
+- Dependency declarations
+- No circular dependencies
+- All dependencies reference valid packages
+
+## Running Tests
+
+```bash
+npm run test:unit
+```
+
+## Adding New Tests
+
+When adding new integration tests:
+1. Create test files with `.test.ts` extension
+2. Import from `vitest`
+3. Use descriptive test names
+4. Follow existing patterns
