getting error in all the tests of fundme

[khushbusandhu]

this is my unit test code

const { deployments, ethers, getNamedAccounts } = require("hardhat");
const { assert, expect } = require("chai");
require("@nomiclabs/hardhat-ethers");
const { developmentChains } = require("../../helper-hardhat-config");

describe("FundMe", async function () {
  let fundMe;
  let deployer;
  let mockV3Aggregator;
  const sendValue = ethers.parseEther("1");
  beforeEach(async function () {
    deployer = (await getNamedAccounts()).deployer;
    await deployments.fixture(["all"]);
    fundMe = await ethers.getContractAt("FundMe", deployer);
    mockV3Aggregator = await ethers.getContractAt("MockV3Aggregator", deployer);
  });

  describe("constructor", function () {
    it("sets the aggregator addresses correctly", async () => {
      const response = await fundMe.target;
      assert.equal(response, mockV3Aggregator.target);
    });
  });
  describe("fundme", function () {
    it("Fails if you don't send enough ETH", async () => {
      await expect(fundMe.fund()).to.be.revertedWith(
        "You need to spend more ETH!"
      );
    });
    it("Updates the amount funded data structure", async () => {
      await fundMe.fund({ value: sendValue });
      const response = await fundMe.getAddressToAmountFunded(deployer);
      assert.equal(response.toString(), sendValue.toString());
    });
    it("Adds funder to funders array", async () => {
      await fundMe.fund({ value: sendValue });
      const funder = await fundMe.getFunder(0);
      assert.equal(funder, deployer);
    });
  });
  describe("withdraw", function () {
    beforeEach(async () => {
      await fundMe.fund({ value: sendValue });
    });
    it("withdraws ETH from a single funder", async () => {
      // Arrange
      const startingFundMeBalance = await ethers.provider.getBalance(
        fundMe.target
      );
      console.log(startingFundMeBalance);
      const startingDeployerBalance = await ethers.provider.getBalance(
        deployer
      );
      console.log(startingDeployerBalance);

      // Act
      const transactionResponse = await fundMe.withdraw();
      const transactionReceipt = await transactionResponse.wait(1);
      console.log(transactionReceipt);
      const { gasUsed, gasPrice } = transactionReceipt;
      const gasCost = gasUsed * gasPrice;
      const endingFundMeBalance = await ethers.provider.getBalance(
        fundMe.target
      );
      console.log(endingFundMeBalance);
      const endingDeployerBalance = await ethers.provider.getBalance(deployer);
      console.log(endingDeployerBalance);

      // Assert
      // Maybe clean up to understand the testing
      assert.equal(endingFundMeBalance, 0);
      assert.equal(
        startingFundMeBalance + startingDeployerBalance,
        endingDeployerBalance + gasCost
      );
    });
  });
});

and this is my terminal output
