here is my staging test below which I am trying to test on goerli network:

const { assert, expect } = require("chai")
const { getNamedAccounts, ethers, network } = require("hardhat")
const { FacetCutAction } = require("hardhat-deploy/dist/types")
const { developmentChains } = require("../../helper-hardhat-config")

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

          beforeEach(async function () {
              const factoryRaffle = await ethers.getContractFactory("Raffle")
              raffle = await factoryRaffle.deploy()
              raffleEntranceFee = await raffle.getEntranceFee()
          })

          describe("fulfillRandomWords", function () {
              it("works with live Chainlink Keepers and Chainlink VRF, we get a random winner", async function () {
                  // enter the raffle
                  console.log("Setting up test...")
                  const startingTimeStamp = await raffle.getLastTimeStamp()
                  const accounts = await ethers.getSigners()

                  console.log("Setting up Listener...")
                  await new Promise(async (resolve, reject) => {
                      // setup listener before we enter the raffle
                      // Just in case the blockchain moves REALLY fast
                      raffle.once("WinnerPicked", async () => {
                          console.log("WinnerPicked event fired!")
                          try {
                              // add our asserts here
                              const recentWinner = await raffle.getRecentWinner()
                              const raffleState = await raffle.getRaffleState()
                              const winnerEndingBalance = await accounts[0].getBalance()
                              const endingTimeStamp = await raffle.getLastTimeStamp()

                              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.log(error)
                              reject(error)
                          }
                      })
                      // Then entering the raffle
                      console.log("Entering Raffle...")

                      await tx.wait(1)
                      console.log("Ok, time to wait...")
                      const winnerStartingBalance = await accounts[0].getBalance()

                      // and this code WONT complete until our listener has finished listening!
                  })
              })
          })
      })

its showing an error that goes like this: Raffle Staging Tests "before each" hook for "works with live Chainlink Keepers and Chainlink VRF, we get a random winner": Error: missing argument: in Contract constructor (count=0, expectedCount=6, code=MISSING_ARGUMENT, version=contracts/5.7.0)

I have all the constructor arguments there, I am not sure what is wrong. Can anybody help me out here?

you are not passing the constructor arguments in your test in the beforeEach code block, here is how you code do that using ether.js

beforeEach(async function () {
const factoryRaffle = await ethers.getContractFactory("Raffle")
raffle = await factoryRaffle.deploy(arg1, arg2, arg3, { gasLimit: 1000000 })
raffleEntranceFee = await raffle.getEntranceFee()

})
