+# Testing Strategy
+
+This project uses a focused testing approach that combines unit tests with integration tests that use examples as test fixtures.
+
+## Testing Philosophy
+
+**"Examples as Test Fixtures"** - Our examples serve dual purposes:
+1. **Documentation** - Show real-world usage patterns
+2. **Test Fixtures** - Provide real projects to test against
+
+This approach ensures the library works in real scenarios while keeping examples clean and focused.
+
+## Test Structure
+
+### Unit Tests (`packages/arkenv/src/*.test.ts`)
+- Test individual functions and edge cases
+- Validate error handling and type checking
+- Fast, isolated tests for core logic
+
+### Integration Tests (`packages/vite-plugin/src/*.test.ts`)
+- Test the vite plugin using the `with-vite-react-ts` example as a fixture
+- Validate that the plugin works with real Vite projects
+- Ensure environment variable injection works correctly
+
+## Running Tests
+
+```bash
+# Run all tests
+pnpm test -- --run
+
+# Run only unit tests
+pnpm test --project arkenv -- --run
+
+# Run only vite plugin tests
+pnpm test --project vite-plugin -- --run
+```
+
+## Test Coverage
+
+### Core Package (`arkenv`)
+- ✅ Environment variable parsing and validation
+- ✅ Type checking and error handling
+- ✅ Default value handling
+- ✅ Custom type validation (host, port, etc.)
+
+### Vite Plugin (`@arkenv/vite-plugin`)
+- ✅ Plugin integration with Vite
+- ✅ Environment variable loading and injection
+- ✅ Real project build testing using the example as a fixture
+- ✅ Error handling for missing environment variables
+
+## Benefits of This Approach
+
+1. **Clean Separation** - Examples remain pure examples, not test files
+2. **Real-World Validation** - Plugin tests use actual Vite projects
+3. **Low Maintenance** - Examples don't need test maintenance
+4. **Focused Testing** - Each package tests its own functionality
+5. **Integration Coverage** - Plugin tests catch real-world issues
+
+## Examples
+
+Examples are kept clean and focused on demonstrating usage:
+- `examples/basic` - Basic Node.js usage
+- `examples/with-bun` - Bun runtime usage  
+- `examples/with-vite-react-ts` - Vite plugin usage (also used as test fixture)
+
+## CI Integration
+
+The CI pipeline runs:
+- Unit tests for core functionality
+- Integration tests for the vite plugin using real examples
+- Ensures no regressions in real-world usage scenarios
+
+This approach provides comprehensive test coverage while maintaining clean, focused examples.
