Lesson 9: AssertionError: Unspecified AssertionError in fulfillRandomWords

[zubeirarhesta]

Hi Guys, I found similiar problem in #4479, but this different

Here is the error:

and here my test that failed:

 it("picks a winner, resets, and sends money", async () => {
                  const additionalEntrances = 3 // to test
                  const startingIndex = 2
                  for (let i = startingIndex; i < startingIndex + additionalEntrances; i++) {
                      // i = 2; i < 5; i=i+1
                      raffle = raffleContract.connect(accounts[i]) // Returns a new instance of the Raffle contract connected to player
                      await raffle.enterRaffle({ value: raffleEntranceFee })
                  }
                  const startingTimeStamp = await raffle.getLatestTimeStamp() // stores starting timestamp (before we fire our event)

                  // This will be more important for our staging tests...
                  await new Promise(async (resolve, reject) => {
                      raffle.once("WinnerPicked", async () => {
                          // event listener for WinnerPicked
                          console.log("WinnerPicked event fired!")
                          // assert throws an error if it fails, so we need to wrap
                          // it in a try/catch so that the promise returns event
                          // if it fails.
                          try {
                              // Now lets get the ending values...
                              const recentWinner = await raffle.getRecentWinner()
                              const raffleState = await raffle.getRaffleState()
                              const winnerBalance = await accounts[2].getBalance()
                              const endingTimeStamp = await raffle.getLatestTimeStamp()
                              await expect(raffle.getPlayer(0)).to.be.reverted
                              // Comparisons to check if our ending values are correct:
                              assert.equal(recentWinner.toString(), accounts[2].address)
                              assert.equal(raffleState, 0)
                              assert(endingTimeStamp > startingTimeStamp)
                              assert.equal(
                                  winnerBalance.toString(),
                                  startingBalance // startingBalance + ( (raffleEntranceFee * additionalEntrances) + raffleEntranceFee )
                                      .add(
                                          raffleEntranceFee
                                              .mul(additionalEntrances)
                                              .add(raffleEntranceFee)
                                      )
                                      .toString()
                              )
                              resolve() // if try passes, resolves the promise
                          } catch (e) {
                              reject(e) // if try fails, rejects the promise
                          }
                      })

                      // kicking off the event by mocking the chainlink keepers and vrf coordinator
                      const tx = await raffle.performUpkeep("0x")
                      const txReceipt = await tx.wait(1)
                      const startingBalance = await accounts[2].getBalance()
                      await vrfCoordinatorV2Mock.fulfillRandomWords(
                          txReceipt.events[1].args.requestId,
                          raffle.address
                      )
                  })
              })

and from the error message, the problem went to this specific line:

assert(endingTimeStamp > startingTimeStamp)

almost forgot and this is the getter function from Raffle.sol:

function getEntranceFee() public view returns (uint256) {
        return i_entranceFee;
    }

    function getPlayer(uint256 index) public view returns (address) {
        return s_players[index];
    }

    function getRecentWinner() public view returns (address) {
        return s_recentWinner;
    }

    function getRaffleState() public view returns (RaffleState) {
        return s_raffleState;
    }

    function getNumWords() public pure returns (uint256) {
        return NUM_WORDS;
    }

    function getNumberOfPlayers() public view returns (uint256) {
        return s_players.length;
    }

    function getLatestTimeStamp() public view returns (uint256) {
        return s_lastTimeStamp;
    }

    function getRequestConfirmations() public pure returns (uint256) {
        return REQUEST_CONFIRMATIONS;
    }

    function getInterval() public view returns (uint256) {
        return i_interval;
    }

function getLatestTimeStamp() public view returns (uint256) {
        return s_lastTimeStamp;
    }

all the rest fo the tests are successful, only this one. Really hope for the answer. :)
I'm sorry for bad english and bad formatting.

Hmm it should work but i guess if nothing in mind you can log endingTimeStamp > startingTimeStamp and comment some of other asserts and see exactly where the problem is.

Thank You for your reply 🙂 I'll try it.

@zubeirarhesta got the same error. so if you are facing issue for eg as you said

assert(endingTimeStamp > startingTimeStamp)

change it to

assert.isAbove(endingTimeStamp,startingTimeStamp)

Seems like some issue with bigInt in JS in my case it was with

assert.isAbove(winnerEndingBalance, winnerStartingBalance)

I hope this helps

Bro thanks for help me up. I am sorry for the long respond. Actually, can you help with upgradeable contract using chugsplash? Pada tanggal Min, 29 Jan 2023 pukul 00.20 Rajan lagah < ***@***.***> menulis:
