I am facing this error here: 1) Raffle Staging Tests "before each" hook for "works with live Chainlink Keepers and Chainlink VRF, we get a random winner": Error: No Contract deployed with name Raffle at Object.getContract (node_modules/@nomiclabs/hardhat-ethers/src/internal/helpers.ts:447:11) at processTicksAndRejections (node:internal/process/task_queues:96:5) at Context. (test/staging/Raffle.staging.test.js:12:18)

can anybody help me out with this?

Are you sure this code block is valid?

        deployer = (await getNamedAccounts()).deployer;
        raffle = await ethers.getContract("Raffle", deployer);

I would say it is not correct, but I also assume there are may be multiple ways to deploy a contract in tests.

Here is how I did a similar case:

import { time, loadFixture } from "@nomicfoundation/hardhat-network-helpers";
import "./SwapChainV2";
import "./SwapValue";

describe.only("SwapChain V2 test", async function () {

    async function deploy() {
        const factoryUtils = await ethers.getContractFactory("Utils");
        const contractUtils = await factoryUtils.deploy();

        const factorySwapValue = await ethers.getContractFactory("SwapValue");
        const contractValue = await factorySwapValue.deploy();

        const factory = await ethers.getContractFactory("SwapChainV2");
        const contractSwapChain = await factory.deploy(

        const accounts = await ethers.getSigners();

        return { contractSwapChain, contractValue, contractUtils }

    it("On register new user, get users call returns relevant count", async function() {
        const { contractSwapChain } = await loadFixture(deploy);
        // the rest of the test case
