No Contract deployed with Name "FundMe"

[Nikhil8847]

while creating unit test for FundMe Contract, I have got this error.

Error: No Contract deployed with name FundMe

The testing code is below

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

describe("FundMe", async function() {
    let fundMe
    let deployer
    let mockV3Aggregator
    beforeEach(async function() {
        // const { accounts } = await ethers.getSigners()
        // const accountsZero = accounts[0]
        deployer = (await getNamedAccounts()).deployer
        deployments.fixture(["all"])
        fundMe = await ethers.getContract("FundMe", deployer)
        mockV3Aggregator = await ethers.getContract(
            "MockV3Aggregator",
            deployer
        )
    })
    describe("constructor", async function() {
        it("Sets the Aggregator address correctly", async function() {
            const response = await fundMe.priceFeed()
            assert.equal(response, mockV3Aggregator.address)
        })
    })
})

I have checked the deployments folder and it too show the deployments have been made: The full error is as follows:

  FundMe
    constructor

      1) "before each" hook for "Sets the Aggregator address correctly"

  0 passing (1s)
  1 failing

  1) FundMe
       "before each" hook for "Sets the Aggregator address correctly":

I have tried redeploying using yarn hardhat deploy and deploy happens without any error, but test still doesn't detect the deployments. I have tried other hit and trials methods too, but no luck. Does anyone know some troublsheeoting tips.

Ok, I got it fixture is async function, but I forgot to put await.
