• I am testing the last it function:

`

it("picks a winner, reset the lottery, and send money", async () => {
          const additionalEntrants = 3
          const startingAccountIndex = 1 // deployer = 0
          const accounts = await ethers.getSigners()


          for (let i = startingAccountIndex; i < startingAccountIndex + additionalEntrants; i++) {
            const accountConnectedLottery = lottery.connect(accounts[i])
            await accountConnectedLottery.enterLottery({ value: lotteryEntranceFee })
          }
          const startingTimeStamp = await lottery.getLatestTimeStamp()

          // performUpkeep (mock being chainlink keeper)
          // fulfilledRandomWords (mock being chainlink VRF)
          // we will have to wait for fulfilledRandomWords to be called
          await new Promise(async (resolve, reject) => {
            lottery.once("WinnerPicked", async () => {
              console.log("Found the event!")
              try {
                const recentWinner = await lottery.getRecentWinner()
                const lotteryState = await lottery.getLotteryState()
                const endingTimeStamp = await lottery.getLatestTimeStamp()
                const numPlayers = await lottery.getNumPlayers()
                const winnerEndingBalance = await accounts[1].getBalance()

                console.log(recentWinner)
                console.log(accounts[0].address)
                console.log(accounts[1].address)
                console.log(accounts[2].address)
                console.log(accounts[3].address)

                assert.equal(numPlayers.toString(), "0")
                assert.equal(lotteryState.toString(), "0")
                assert.equal(

                  winnerStartingBalance
                    .add(lotteryEntranceFee.mul(additionalEntrants).add(lotteryEntranceFee))
                    .toString()
                )
                assert(endingTimeStamp > startingTimeStamp)

                resolve()
              } catch (e) {
                reject(e)
              }
            })
            // setting up the listener
            //below, we will fire the event, and the listener will pick it up , and resolve
            const tx = await lottery.performUpkeep([])
            const txReciept = await tx.wait(1)
            const winnerStartingBalance = await accounts[1].getBalance()
            await vrfCoordinatorV2Mock.fulfillRandomWords(
              txReciept.events[1].args.requestId,
              lottery.address
            )
          })
        })

@muhammet72 you need to call .toString() with raffleEntranceFee
.mul(additionalEntrances)
.add(raffleEntranceFee) and you called it outside
replace this code

 assert.equal(
                                  winnerEndingBalance.toString(),
                                  winnerStartingBalance
                                      .add(
                                          lotteryEntranceFee
                                              .mul(additionalEntrants)
                                              .add(lotteryEntranceFee)
                                      )
                                      .toString()
                              )

to this

 assert.equal(
                                  winnerEndingBalance.toString(),
                                  winnerStartingBalance
                                      .add(
                                          lotteryEntranceFee
                                              .mul(additionalEntrants)
                                              .add(lotteryEntranceFee) .toString()
                                      )
                                    
                              )

it will work .
