概要
This skill provides a comprehensive framework for testing Solidity smart contracts, bridging the gap between standard unit testing and advanced blockchain-specific validation. It enables developers to set up robust test suites with Hardhat and Foundry, perform property-based fuzzing, simulate complex mainnet environments through forking, and monitor gas consumption. Whether you are building DeFi protocols or NFT collections, this skill ensures your code is resilient against edge cases and security vulnerabilities before deploying to production.
