my code is
const { assert, expect } = require("chai");
const { network, getNamedAccounts, ethers } = require("hardhat");
const { developmentChains } = require("../../helper-hardhat-config.js");

developmentChains.includes(network.name)
? describe.skip
: describe("Raffle", function () {
let raffle, raffleEntranceFee, deployer;

		beforeEach(async function () {
			deployer = (await getNamedAccounts()).deployer;
			raffle = await ethers.getContract("Raffle", deployer);
			raffleEntranceFee = await raffle.getEntranceFee();
		});
		describe("fulfillRandomWords", function () {
			it("works with live Chainlink keepers and Chainlink VRF, wwe get a random winner", async function () {
				const startingTimeStamp = await raffle.getLatestTimeStamp();
				const accounts = await ethers.getSigners();

				await new Promise(async (resolve, reject) => {
					raffle.once("WinnerPicked", async () => {
						console.log("WinnerPicked event fired!");
						resolve();

						try {
							const recentWinner = await raffle.getRecentWinner();
							const raffleState = await raffle.getRaffleState();
							const winnerEndingBalance = await accounts[0].getBalance();
							const endingTimeStamp = await raffle.getLatestTimeStamp();

							await expect(raffle.getPlayer(0)).to.be.reverted;
							assert.equal(recentWinner.toString(), accounts[0].address);
							assert.equal(raffleState, 0);
							assert.equal(
								winnerEndingBalance.toString(),
								winnerStartingBalance.add(raffleEntranceFee).toString()
							);
							assert(endingTimeStamp > startingTimeStamp);
							resolve();
						} catch (error) {
							console.error(error);
							reject(error);
						}
					});

					await raffle.enterRaffle({ value: raffleEntranceFee });
					const winnerStartingBalance = await accounts[0].getBalance();
				});
			});
		});
  });

Hello @umairahmed88, there is a small problem in your hardhat.config file. The mocha config is inside the namedAccounts config, and for this reason is not being accessed by hardhat and the test is running with the default time of 40000 ms which is too low for this staging test.

Let me know how it goes.

Hi @umairahmed88 @IceCreamSandwich98

If you search for same issue there are already tons of same topics solved in discussion tab of this course. If you have setup upKeep as custom you can also send to upKeep and VRF subscription more LINK's like 25 and there is chance that it will work. If still you will be facing issues just withdraw LINK's.
