Create test files for each module 2. Implement mock systems for external dependencies 3. Set up test environments with proper isolation 4. Add performance monitoring tools 5. Implement security checks and validations 6. Create cleanup routines for all operations ## Current Implementation Status ### Completed ✅ - Basic mouse movement and clicking - Basic keyboard input - Screen capture and size - Cursor position tracking - Basic active window detection (title, size, and position) - Mouse scrolling (up/down) - Window management functions (list, focus, resize, reposition) - Key combinations support - Clipboard operations (get, set, check, clear) - Advanced mouse operations (drag, speed control) - Advanced keyboard operations (key holding/releasing) - Unit tests for keyboard module - Unit tests for screen module - Unit tests for tools handler ### In Progress 🔄 - Integration testing setup - Security validation implementation - Performance monitoring tools - Error handling improvements ### Pending ❌ - UI element finding - Window minimize/restore operations (unsupported in libnut-core) - Complete integration test suite - Security test implementation - Performance test suite - Comprehensive error handling tests ### Unsupported in libnut-core ⛔ - Advanced screen information (multiple monitors, DPI settings, etc.) - Only main display size and capture are supported - No built-in support for secondary monitors - Would require implementing new methods using platform-specific APIs: - Windows: EnumDisplayMonitors() - Linux: XRandR extension - macOS: NSScreen API ## References - NutJS GitHub Repository: https://github.com/nut-tree/nut.js - API Documentation: https://nutjs.dev/
