+# Mindcraft Testing
+
+Test suite for the Mindcraft project.
+
+## Structure
+
+- `unit/` - Unit tests for individual components
+- `integration/` - Integration tests for component interactions
+
+## Running Tests
+
+```bash
+npm test              # Run all tests
+npm run test:watch    # Watch mode
+npm run test:coverage # With coverage
+npm run test:ci       # CI mode
+```
+
+## Test Files
+
+### Unit Tests
+- `commands.test.js` - Command parsing and execution
+- `utils.test.js` - Utility functions
+- `task.test.js` - Task validation and processing
+- `settings.test.js` - Settings configuration
+- `models.test.js` - Model configuration and API selection
+
+### Integration Tests
+- `basic.test.js` - Module loading and configuration
+
+## Guidelines
+
+1. Tests verify existing functionality without modifications
+2. Mock external dependencies (APIs, file system, network)
+3. Test edge cases and error conditions
+4. Use descriptive test names
+5. Keep tests independent
+
+## Coverage
+
+Tests cover core functionality while avoiding:
+- Minecraft server connections
+- External API calls
+- File system modifications
+
+## CI/CD
+
+Automated testing on:
+- Push to `develop`, `unit-test`, `main` branches
+- Pull requests to `develop` or `main` branches
+- Node.js versions 18.x and 20.x
+
+Coverage reports uploaded to Codecov.
