Web3 Testing

This covers the essential testing patterns you'll actually use in production smart contract development. It sets up proper Hardhat and Foundry configurations with gas reporting, coverage, and mainnet forking capabilities. The examples show real testing scenarios like fuzzing with Foundry's property-based tests, impersonating whale accounts for DeFi integration tests, and using fixtures to avoid repetitive setup. What makes this genuinely useful is the focus on advanced patterns like snapshot testing for complex state changes and gas optimization comparisons between different implementations. If you're building anything beyond basic contracts, you'll need these testing strategies to catch edge cases and ensure your contracts behave correctly under real market conditions.
