Cannot solve Error: Invalid Chai property: revertedWith

[SamarthBagga]

I am trying to run a test on my contract using hardhat and chai. But I am running into this error. I have tried install ethereum-waffle. But it did not solve the problem. I also added ethereum-waffle using require to my hardhat config but that gave this error-

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './lib/utils' is not defined by "exports" in /home/samarth/web3/hardhat-fundme/node_modules/ethers/package.json

}
error Command failed with exit code 1.

Here is my FundMe.test file-

const { deployments, ethers, getNamedAccounts } = require("hardhat")
const { assert, expect } = require("chai")
describe("FundMe", async function () {
    let fundMe
    let deployer
    let mockV3Aggregator
    beforeEach(async function () {
        // const accounts = await ethers.getSigners()
        // const accountZero = accounts[0]
        deployer = (await getNamedAccounts()).deployer
        await deployments.fixture(["all"])
        fundMe = await ethers.getContract("FundMe", deployer)
        mockV3Aggregator = await ethers.getContract(
            "MockV3Aggregator",
            deployer
        )
    })
    describe("constructor", async function () {
        it("sets the aggregator addresses correctly", async function () {
            const response = await fundMe.gePriceFeed()
            assert.equal(response, await mockV3Aggregator.getAddress())
        })
    })

    describe("fund", async function () {
        it("Fails if you dont send enough ETH", async function () {
            await expect(fundMe.fund()).to.be.revertedWith(
                "You need to spend more"
            )
        })
    })
})

please share your repo

Hi @alfaqi Here is the repo-
link to the repo

[alfaqi]

I made some changes,
Delete artifacts cache node_modules yarn.lock, then install these packages:
1- package.json

{
  "devDependencies": {
    "@chainlink/contracts": "^0.6.1",
    "@nomicfoundation/hardhat-chai-matchers": "1",
    "@nomicfoundation/hardhat-ethers": "^3.0.0",
    "@nomicfoundation/hardhat-network-helpers": "^1.0.8",
    "@nomicfoundation/hardhat-toolbox": "^3.0.0",
    "@nomicfoundation/hardhat-verify": "^1.0.0",
    "@nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers",
    "@nomiclabs/hardhat-etherscan": "^3.1.7",
    "@typechain/ethers-v6": "^0.4.0",
    "@typechain/hardhat": "^8.0.0",
    "chai": "^4.3.7",
    "ethers": "^6.6.2",
    "hardhat": "^2.16.1",
    "hardhat-deploy": "^0.11.34",
    "hardhat-gas-reporter": "^1.0.9",
    "solidity-coverage": "^0.8.4",
    "typechain": "^8.2.0",
    "dotenv": "^16.3.1"
  }
}

2- hardhat.config.js
after you install packages, delete all requires and put just these:

require("@nomicfoundation/hardhat-toolbox")
require("dotenv").config()
require("hardhat-deploy")

3- FundMe.test.js
change these:

- const sendValue = ethers.utils.parseEther("1")
+ const sendValue = ethers.parseEther("1")

- const response = await fundMe.gePriceFeed()
+ const response = await fundMe.getPriceFeed()

- const response = await fundMe.addressToAmountFunded(deployer)
+ const response = await fundMe.getAddressToAmountFunded(deployer)

the message of revertedWith

- "You need to spend more"
+ "You need to spend more ETH!"

I hope this helps

Hi @alfaqi your advice has solved the issue ! Thank you so much ! But now I am getting this error even though I am parsing 1 eth-

FundMe
    constructor
      ✓ sets the aggregator addresses correctly
    fund

      1) Fails if you dont send enough ETH
      ✓ amount funded


  2 passing (3s)
  1 failing

  1) FundMe
       fund
         Fails if you dont send enough ETH:
     AssertionError: Expected transaction to be reverted with reason 'You need to spend more ETH', but it reverted with reason 'You need to spend more ETH!'
      at processTicksAndRejections (internal/process/task_queues.js:95:5)
      at Context.<anonymous> (test/unit/FundMe.test.js:28:13)



error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

The transaction is reverting with the message from the contract and not the test for some reason.

[alfaqi]

you are missing ! just that.
AssertionError: Expected transaction to be reverted with reason 'You need to spend more ETH', but it reverted with reason 'You need to spend more ETH!'

try to read the error, and you will get it.

[alfaqi]

you must write exactly what you wrote in your contract.

[SamarthBagga]

yes it worked thank you

[NickoMenty]

this helped me

yarn remove ethereum-waffle

yarn add --dev ethereum-waffle@3.0.0

[AntoineF4C5]

This did the trick for me ! Thanks
