I try to run a simple test in Hardhat but for some reason it is not working it always returns:

0 passing (1ms)

This is the test:

const { ethers } = require("hardhat")
const { expect, assert } = require("chai")

describe("SimpleStorage", async function () {
  let simpleStorageFactory, simpleStorage
  beforEach(async function () {
    simpleStorageFactory = await ethers.getContractFactory("SimpleStorage")
    simpleStorage = await simpleStorageFactory.deploy()
  })

  it("Should start with a favorite number of 0", async function () {
    const currentValue = await simpleStorage.retrieve()
    const expectedValue = "0"

    assert.equal(currentValue.toString(), expectedValue)
  })
})

When I run:

yarn hardhat test

it returns 0. As if the test file is empty

0 passing (1ms)

This is hardhat.config.js:

require("@nomicfoundation/hardhat-toolbox")
require("dotenv").config()
require("@nomiclabs/hardhat-etherscan")
require("./tasks/block_number")
require("@nomicfoundation/hardhat-chai-matchers")
require("@nomiclabs/hardhat-ethers")
require("@nomiclabs/hardhat-waffle")

const RINKEBY_RPC_URL = process.env.RINKEBY_RPC_URL
const PRIVATE_KEY = process.env.PRIVATE_KEY
const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  defaultNetwork: "hardhat",
  networks: {
    rinkeby: {
      url: RINKEBY_RPC_URL,
      accounts: [PRIVATE_KEY],
      chainId: 4,
    },
    localhost: {
      url: "http://127.0.0.1:8545",

      chainId: 31337,
    },
  },
  solidity: "0.8.8",
  etherscan: {
    apiKey: ETHERSCAN_API_KEY,
  },
}

    what's your folder structure / name of the file. It has to be in the "test" folder

  • @PinPiguin consider using my Hardhat-based template so you don't have to configure this yourself.

Your beforEach(async function () is missing an "e" at the end of before

Should be beforeEach(async function ()

I think the issue is that you have the async included in the top level describe block. Removing it should allow your tests to be executed. Replacing line 4 with this should solve your issue:

describe("SimpleStorage", function () {
