Lesson 9: TypeError: Cannot read properties of undefined (reading 'checkUpkeep') at Context.<anonymous> (test\unit\Raffle.test.js:80:68)

I am getting this error when i run "yarn hardhat test" :
1) Raffle Unit Tests
checkUpkeep
returns false if people haven't sent any ETH:
TypeError: Cannot read properties of undefined (reading 'checkUpkeep')
at Context. (test\unit\Raffle.test.js:80:68)

Here is my Raffle.test.js :
describe("checkUpkeep", function () {
it("returns false if people haven't sent any ETH", async () => {
await network.provider.send("evm_increaseTime", [Number(interval) + 1]);
await network.provider.request({ method: "evm_mine", params: [] });
const { upkeepNeeded } = await raffle.callStatic.checkUpkeep("0x"); // upkeepNeeded = (timePassed && isOpen && hasBalance && hasPlayers);
assert(!upkeepNeeded);
})

To fix this issue, ensure that the raffle contract is properly deployed and initialized before the test runs. Here’s how you can update your Raffle.test.js file:

Updated Raffle.test.js

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

describe("Raffle Unit Tests", function () {
    let raffle;
    let interval;

    beforeEach(async () => {
        // Deploy the Raffle contract
        await deployments.fixture(["all"]); // Ensure all deployments are run

        // Get the deployed Raffle contract instance
        const RaffleDeployment = await deployments.get("Raffle");
        raffle = await ethers.getContractAt(
            RaffleDeployment.abi,
            RaffleDeployment.address
        );

        // Get the interval from the contract
        interval = await raffle.getInterval();
    });

    describe("checkUpkeep", function () {
        it("returns false if people haven't sent any ETH", async () => {
            // Fast-forward time to exceed the interval
            await network.provider.send("evm_increaseTime", [Number(interval) + 1]);
            await network.provider.request({ method: "evm_mine", params: [] });

            // Call checkUpkeep and check the result
            const { upkeepNeeded } = await raffle.callStatic.checkUpkeep("0x"); // upkeepNeeded = (timePassed && isOpen && hasBalance && hasPlayers);
            assert(!upkeepNeeded);
        });
    });
});
