Tooltip Component Testing Summary

This document provides a comprehensive overview of the testing infrastructure implemented for the Tooltip component in the Rust shadcn/ui project.

🎯 Overview

The Tooltip component has been thoroughly tested across multiple dimensions to ensure quality, reliability, and cross-framework parity. The testing infrastructure covers:

• Unit Tests - Framework-specific component validation
• Integration Tests - Cross-framework parity and consistency
• Accessibility Tests - ARIA compliance and usability
• Theme Tests - Visual consistency across design variants
• Build Tests - Compilation and dependency validation
• Documentation Tests - API documentation generation
