Lesson 7: FundMe.test.js fails locally with timeout error

[0xCardiE]

Sol files all or compiled correctly and so far all have been working in this lesson as in YT video. Then I try to write tests and they just fail.
This is the error I get

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.

The code is below, also tried with other functions the same thing happens. I tried with just directly c/p from GitHub repo, also fails

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

describe("FundMe", async function () {
  let fundMe;
  let mockV3Aggregator;
  let deployer;
  beforeEach(async () => {
    // const accounts = await ethers.getSigners()
    // deployer = accounts[0]
    deployer = (await getNamedAccounts()).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);
    });
  });
});

@adriadrop You can add this in the hardhat config file.

mocha: {
    timeout: 100000000
  },

@adriadrop you can also add this to package.json file

"scripts": {
    "test": "mocha --timeout 1000000"
}

Is it normal to that test take so much time locally? Was expecting as usual local deployment and scripts take just few seconds why would mocha tests take so much more?

[alymurtazamemon]

@adriadrop Yes, if our single test computations are more time taking than the default settings for mocha tests then we need to manually increase the time for it.

Hope it clears your query!

Problem wasnt that. Just wrong config for

waitConfirmations: network.config.blockConfirmations || 2,

seems that local hardhat just mines one block after trx so if you have anything higher then 1 it never reaches. So this part was wrong and in tests it never reached it so it would time out whatever I put.

thnx for suggestions, hopefully this helps someone else with similar issue.
