Chapter 7: Error: Timeout of 40000ms exceeded. For async tests and hooks, ensure "done()" is called

[b0nesss]

At 11:18:04 of this course while running the unit test I am facing an error :

FundMe
    constructor
      1) "before each" hook for "sets the aggregator addresses correctly"


  0 passing (40s)
  1 failing

  1) FundMe
       "before each" hook for "sets the aggregator addresses correctly":
     Error: Timeout of 40000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (/home/bones/vs-code/pat-col-tut/hardhat-fund-me-fcc/test/unit/FundMe.test.js)
      at listOnTimeout (node:internal/timers:557:17)
      at processTimers (node:internal/timers:500:7)



error Command failed with exit code 1.

Here's my FundMe.test.js file code:

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

describe("FundMe" , function(){
    let fundMe
    let deployer
    let mockV3Aggregator
    beforeEach(async ()=> {
        //deploy our fundMe contract using hardhat-deploy
        deployer = (await getNamedAccounts()).deployer
        // const accounts = await ethers.getSigners()
        // const accountZero = accounts[0]
        //above 2 are also ways of getting account or deployer
        await deployments.fixture(["all"])
        fundMe = await ethers.getContract("FundMe" , deployer)
        mockV3Aggregator = await ethers.getContract("MockV3Aggregator" , deployer)
    });
    describe("constructor" , function() {
        it("sets the aggregator addresses correctly" , async ()=> {
            const response = await fundMe.getpriceFeed()
            assert.equal(response,mockV3Aggregator.address)
        })
    })
})

I tried using

this.timeout(180000);

before the it statement but that didn't help.

I also tried adding

mocha:{
     timeout:120000,
}

in hardhat.config.js file but even that didn't help out and Timeout of 180000ms exceeded was shown in the error.

Please solve this issue.

P.S. I am using the same versions of dev dependencies given in github repo

check for this getpriceFeed() may be it's like this getPriceFeed()

const response = await fundMe.getPriceFeed()

[b0nesss]

In my FundMe.sol I've declared price feed variable as

AggregatorV3Interface public priceFeed;

so I think it should be

const response = await fundMe.getpriceFeed();

Nevertheless, I tried changing it and still got the same error mentioned above. I wonder if its even getting to that point in 40s because otherwise it would have showed some error in that line.
I tried commenting out this test and wrote a test for fund() function and got the same error as mentioned above.

nvm got it
There was actually some error in deploy part where I had fixed no. of block confirmations as 6 for both localhost and sepolia and I didn't deploy in localhost during that part so never got this error. But in testing it was waiting for 6 block confirmations in localhost which won't happen and hence those timeouts.
