Lesson 7: Error: invalid address or ENS name (argument="name", value=undefined, code=INVALID_ARGUMENT, version=contracts/5.7.0)

[vaibhavtevatia]

I'm having trouble testing my fund function. I have tried all the suggested solutions in this discussion (#2745) but none of them seems to work for me. Any suggestion will be appreciated.

Test script:

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

describe("FundMe", async function () {
    let fundMe = deployments
    let deployer
    let mockV3Aggregator
    const sendValue = ethers.utils.parseEther("50")
    beforeEach(async () => {
        const deployer = (await getNamedAccounts()).deployer
        await deployments.fixture(["all"])
        fundMe = await ethers.getContract("FundMe", deployer)
        mockV3Aggregator = await ethers.getContract(
            "MockV3Aggregator",
            deployer
        )
    })
    describe("constructor", async () => {
        it("sets the aggregator addresses correctly", async () => {
            const response = await fundMe.priceFeed()
            assert.equal(response, mockV3Aggregator.address)
        })
    })
    describe("fund", async () => {
        it("fails, not enough ETH", async () => {
            await expect(fundMe.fund()).to.be.revertedWith(
                "You need to spend more ETH!"
            )
        })
        it("updated the amount funded data structure", async () => {
            await fundMe.fund({ value: sendValue })
            const response = await fundMe.getAddressToAmountFunded(deployer)
            assert.equal(response.toString(), sendValue.toString())
        })
    })
})

}

@vaibhavtevatia In the test, you are defined the deployer again;

- const deployer = (await getNamedAccounts()).deployer
+ deployer = (await getNamedAccounts()).deployer

@alymurtazamemon Thank you, I just missed it somehow.
