# Web3 Smart Contract Testing Master comprehensive testing strategies for smart contracts using Hardhat, Foundry, and advanced testing patterns. ## When to Use This Skill - Writing unit tests for smart contracts - Setting up integration test suites - Performing gas optimization testing - Fuzzing for edge cases - Forking mainnet for realistic testing - Automating test coverage reporting - Verifying contracts on Etherscan ## Hardhat Testing Setup ```javascript // hardhat.config.js require("@nomicfoundation/hardhat-toolbox"); require("@nomiclabs/hardhat-etherscan"); require("hardhat-gas-reporter"); require("solidity-coverage"); module.exports = { solidity: { version: "0.8.19", settings: { optimizer: { enabled: true, runs: 200, }, }, }, networks: { hardhat: { forking: { url: process.env.MAINNET_RPC_URL, blockNumber: 15000000, }, }, goerli: { url: process.env.GOERLI_RPC_URL, accounts: [process.env.PRIVATE_KEY], }, }, gasReporter: { enabled: true, currency: "USD", coinmarketcap: process.env.COINMARKETCAP_API_KEY, }, etherscan: { apiKey: process.env.ETHERSCAN_API_KEY, }, }; ``` ## Unit Testing Patterns ```javascript const { expect } = require("chai"); const { ethers } = require("hardhat")

What does the web3-testing skill do?
Test smart contracts comprehensively using Hardhat and Foundry with unit tests, integration tests, and mainnet forking. Use when testing Solidity contracts, setting up blockchain test suites, or validating DeFi protocols.
How do I install it?
Run `npx skills add wshobson/agents --skill web3-testing --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From wshobson/agents, a repository with 38,479 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
