The error says that there is no variable named fundme. This is because you have initialized fundme and MockV3Aggregator variables inside the BeforeEach() , therefore describe block of constructor does not know fundme variable.

To fix issue Change the code from:

describe("FundMe", async () => {
    beforeEach(async function () {
        let fundMe
        let deployer
        let MockV3Aggregator
        //deploy our fundme contract
        // using hardhat deploy
        deployer = (await getNamedAccounts()).deployer
        await deployments.fixture(["all"])
        fundMe = await ethers.getContractAt("FundMe", deployer)
        MockV3Aggregator = await ethers.getContractAt(
            "MockV3Aggregator",
            deployer,
        )
    })
    ```
    
    TO:
    
    ```javascript
    describe("FundMe", async () => {
        let fundMe
        let deployer
        let MockV3Aggregator
        beforeEach(async function () {
        //deploy our fundme contract
        // using hardhat deploy
        deployer = (await getNamedAccounts()).deployer
        await deployments.fixture(["all"])
        fundMe = await ethers.getContractAt("FundMe", deployer)
        MockV3Aggregator = await ethers.getContractAt(
            "MockV3Aggregator",
            deployer,
        )
    })
    ```
    
    The change in the code is that the fundme, deployer and MockV3Aggregator variavbles are initialized outside the beforeEach so that decribe("Constructor") block knows these variable.
    Hope this helps :)
