Sample Hardhat Project

This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, and a script that deploys that contract.

Try running some of the following tasks:

npx hardhat help
npx hardhat test
REPORT_GAS=true npx hardhat test
npx hardhat node
npx hardhat run scripts/deploy.js

---

Carry out a “test coverage” of a Truffle project with HardHat.

Install

npm i @nomiclabs/hardhat-truffle5
npm i @openzeppelin/test-helpers

hardhat.config.js

require("@nomicfoundation/hardhat-toolbox");
require("dotenv").config();
require("@nomiclabs/hardhat-truffle5"); // pour faire des tests truffle sous hardhat
// require("@nomiclabs/hardhat-ethers");
const { INFURIA_ID, PRIVATE_KEY } = process.env;

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  solidity: "0.8.20",
  networks: {
    hardhat_localhost: {
      url: "http://127.0.0.1:8545/",
      chainId: 31337,
    },
    // It works !
    goerli_infu: {
      url: `https://goerli.infura.io/v3/${INFURIA_ID}`,
      accounts:  [`0x${PRIVATE_KEY}`],
      network_id: 5,
    },
  },
};
