# 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");
const { loadFixture, time } = require("@nomicfoundation/hardhat-network-helpers");
describe("Token Contract", function () {
// Fixture for test setup
async function de
