Lesson 9 - Testing - FulfillRandomWords - 0 Passing

[Leonardll]

Hi community, I am getting 0 passing but no error message for the fulfilRandomwords test function. Can someone help me with it, please? I have put the code snippet below :

        describe("checkupkeep", function () {
              it("returns false if people haven't sent ETH", async () => {
                  await network.provider.send("evm_increaseTime", [interval.toNumber() + 1])
                  await network.provider.request({ method: "evm_mine", params: [] })
                  const { upkeepNeeded } = await raffle.callStatic.checkupkeep("0x")
                  assert(!upkeepNeeded)
              })
              it("returns false if raffle isn't open", async () => {
                  await raffle.enterRaffle({ value: raffleEntranceFee })
                  await network.provider.send("evm_increaseTime", [interval.toNumber() + 1])
                  await network.provider.request({ method: "evm_mine", params: [] })
                  // pretend to be a keeper
                  await raffle.performUpkeep([])
                  const raffleState = await raffle.getRaffleState()
                  const { upkeepNeeded } = await raffle.callStatic.checkupkeep("0x")
                  assert.equal(raffleState.toString() == "1", (upkeepNeeded = false))
              })
              it("returns false if enough time hasn't passed", async () => {
                  await raffle.enterRaffle({ value: raffleEntranceFee })
                  await network.provider.send("evm_increaseTime", [interval.toNumber() - 5]) // use a higher number here if this test fails
                  await network.provider.request({ method: "evm_mine", params: [] })
                  const { upkeepNeeded } = await raffle.callStatic.checkupkeep("0x") // upkeepNeeded = (timePassed && isOpen && hasBalance && hasPlayers)
                  assert(!upkeepNeeded)
              })
              it("returns true if enough time has passed, has players, eth, and is open", async () => {
                  await raffle.enterRaffle({ value: raffleEntranceFee })
                  await network.provider.send("evm_increaseTime", [interval.toNumber() + 1])
                  await network.provider.request({ method: "evm_mine", params: [] })
                  const { upkeepNeeded } = await raffle.callStatic.checkupkeep("0x") // upkeepNeeded = (timePassed && isOpen && hasBalance && hasPlayers)
                  assert(upkeepNeeded)
              })
          })
          describe("performUpkeep", function () {
              it("it can only run if checkupkeep is true", async function () {
                  await raffle.enterRaffle({ value: raffleEntranceFee })
                  await network.provider.send("evm_increaseTime", [interval.toNumber() + 1])
                  await network.provider.request({ method: "evm_mine", params: [] })
                  const tx = await raffle.performUpkeep("0x")
                  assert(tx)
              })
              it("reverts when checkupkeep is false", async function () {
                  await expect(raffle.performUpkeep("0X")).to.be.revertedWith(
                      "Raffle_UpkeepNotNeeded"
                  )
              })
              it("updates the raffle state, emits and event", async function () {
                  await raffle.enterRaffle({ value: raffleEntranceFee })

                  const txResponse = await raffle.performUpkeep("0x")
                  const txReceipt = await txResponse.wait(1)
                  const requestId = txReceipt.events[1].args.requestId
                  const raffleState = await raffle.getRaffleState()
                  assert(requestId.toNumber() > 0)
                  assert(raffleState == "1")
              })
          })

          describe("fulfillRandomWords", function () {
              beforeEach(async () => {
                  await raffle.enterRaffle({ value: raffleEntranceFee })
                  await network.provider.send("evm_increaseTime", [interval.toNumber() + 1])
                  await network.provider.request({ method: "evm_mine", params: [] })
              })
              it("can only be called after performupkeep", async () => {
                  await expect(
                      vrfCoordinatorV2Mock.fulfillRandomWords(0, raffle.address)
                  ).to.be.revertedWith("nonexistant request")
                  await expect(
                      vrfCoordinatorV2Mock.fulfillRandomWords(1, raffle.address)
                  ).to.be.revertedWith("nonexistant request")
              })
          })

many thanks in advance :)

@Leonardll Show the complete script or it would be better to push it to GitHub and leave a link here, we will check it.

For quick check make sure describe function spelling is correct and unit tests folder is inside test folder (check spelling as well)

Hi Aly, how is it going? Thanks for coming around to help. Here is the repo's link.

@Leonardll For me it is working, showing errors that you need to solve.

Oh ok, for me when I run hh test --grep "can only be called after performupkeep", i am getting 0 passing but no error message to investigate. Thanks for pointing out the error on the others. I did not have them before to get to the fulfillRandomWords function. I beleive I added some errors in my code trying to fix the latter.
