Lesson 9 . Staging test never ends

[Amrit-ko]

Hello to everyone. My staging test pending after returning Promise. All logic is executed, but the test does not ends. And its not trowing timeout error. Maybe somebody had same issue

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

developmentChains.includes(network.name)
    ? describe.scip
    : describe("Raffle Unit Test", function () {
          let raffle, deployer, raffleEntranceFee

          beforeEach(async () => {
              deployer = (await getNamedAccounts()).deployer
              raffle = await ethers.getContract("Raffle", deployer)
              raffleEntranceFee = await raffle.getEntranceFee()
          })

          describe("fulfillRandomWords", function () {
              it("works with life ChainlinkKeepers and Chainlunk VRF, randomly picks winner", async function () {
                  console.log("Setting up test...")
                  const startingTimeStamp = await raffle.getLatestTimeStamp()
                  const accounts = await ethers.getSigners()

                  console.log("Setting up Listener...")
                  await new Promise(async (resolve, reject) => {
                      raffle.once("WinnerPicked", async () => {
                          console.log("WinnerPicked event fired!")
                          try {
                              const recentWinner = await raffle.getRecentWinner()
                              const winnerEndingBalance = await ethers.provider.getBalance(
                                  accounts[0].address,
                              )
                              const endingTimeStamp = await raffle.getLatestTimeStamp()
                              const raffleState = await raffle.getRaffleState()
                              await expect(raffle.getPlayers(0)).to.be.reverted
                              assert(endingTimeStamp > startingTimeStamp)
                              assert.equal(raffleState, 0n)
                              assert.equal(
                                  winnerEndingBalance,
                                  winnerStartingBalance + raffleEntranceFee,
                              )
                              assert.equal(recentWinner, accounts[0].address)
                              resolve()
                              console.log("resolve done")
                          } catch (error) {
                              console.log(error)
                              reject(error)
                          }
                      })
                      console.log("Entering Raffle...")
                      const tx = await raffle.enterRaffle({ value: raffleEntranceFee })
                      await tx.wait(1)
                      console.log("Ok, time to wait...")
                      const winnerStartingBalance = await ethers.provider.getBalance(
                          accounts[0].address,
                      )
                  })
                  console.log("Success")
              })
          })
      })

i added some extra logs to see where its stops:

Raffle Unit Test
    fulfillRandomWords
Setting up test...
Setting up Listener...
Entering Raffle...
Ok, time to wait...
WinnerPicked event fired!
resolve done
Success

so its resolving promise, but in some reason test is not finishing.

Here is my Repo

hi @Amrit-ko

Please try changing below:

      assert.equal(raffleState, 0n)
      assert.equal(winnerEndingBalance,winnerStartingBalance + raffleEntranceFee,)
      assert.equal(recentWinner, accounts[0].address)

Into:

assert.equal(raffleState, 0)
assert.equal(winnerEndingBalance.toString(), winnerStartingBalance.add(raffleEntranceFee).toString())
assert.equal(recentWinner.toString(), accounts[0].address)

Please also change below in your hardhat.config.js into this:

 sepolia: {
            url: SEPOLIA_RPC_URL,
            accounts: [PRIVATE_KEY],
            chainId: 11155111,
            saveDeployments: true,
            blockConfirmations: 6,
        },
goerli: {
            url: GOERLI_RPC_URL,
            accounts: [PRIVATE_KEY],
            chainId: 5,
            saveDeployments: true,
            blockConfirmations: 6,
        },
    mocha: {
        timeout: 500000,
    },

@Amrit-ko

Whole course is made on ethers v5, so I highly recommend you downgrading from v6 as it will keep causing you tons of errors, up to you if you want to struggle or not.

[Amrit-ko]

Yes you are right, it gives me a lot of struggeling, but while solving all this errors im diving much deeper to understanding of what is going on)))

[Nlferu]

Yup thats true ;) All depends on you then

[Amrit-ko]

I have tried today without any changes) and it passed successfully) but it tooks 21 min)))

Raffle Unit Test
    fulfillRandomWords
Setting up test...
Setting up Listener...
Entering Raffle...
Ok, time to wait...
WinnerPicked event fired!
resolve done
Success
      ✓ works with life ChainlinkKeepers and Chainlink VRF, randomly picks winner (80828662 gas)


  1 passing (21m)

[Nlferu]

Hmm that should not happen, it usually takes like 2 mins max maybe, but I have no idea unfortunately what can cause such delay (network seems to be fine)

[Nlferu]

Oh by the way have you been testing it on both sepolia and goerli?

[Amrit-ko]

no, i tried only in Soplia, but i think i need to try also on Goerli

[TucanCrypto]

I have the same problem as you, I'm using ethers v6 too

In my case, it doesn't finish because the next error is threw before than 20 mins

Error: Timeout of 200000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (/home/joan/hh-fcc/hardhat-smartcontract-lottery-fcc/test/unit/Raffle.test.js)
