lesson 9, some unit tests didn't pass, error: "raffle.performUpKeep is not a function"

[leung100]

when running these unit tests

 describe("checkUpKeep", async function () {
             it("returns false if people havent't sent any ETH yet", async function () {
                 await network.provider.send("evm_increaseTime", [interval.toNumber() + 1])
                 await network.provider.send("evm_mine", [])
                 const { upKeepNeeded } = await raffle.callStatic.checkUpKeep([]) // similating a call by using a staticcall method
                 assert(!upKeepNeeded)
             })
             it("returns false if raffle isn't open", async function () {
                 await raffle.enterRaffle({ value: raffleEnteranceFee })
                 await network.provider.send("evm_increaseTime", [interval.toNumber() + 1])
                 await network.provider.send("evm_mine", [])
                 await raffle.performUpKeep([]) //this will also works: ("0x")
                 const raffleState = await raffle.callStatic.checkUpKeep([])
                 assert.equal(raffleState.toString(), "1")
                 assert.equal(upKeepNeeded, false)

solidity function code:

 function checkUpkeep(
        bytes memory /* checkData */
    )
        public
        view
        override
        returns (
            bool upkeepNeeded,
            bytes memory /* performData */
        )
    {
        bool isOpen = (RaffleState.OPEN == s_raffleState);
        bool timePassed = ((block.timestamp - s_lastTimeStamp) > i_interval);
        bool hasPlayers = s_players.length > 0;
        bool hasBalance = address(this).balance > 0;
        upkeepNeeded = (timePassed && isOpen && hasBalance && hasPlayers);
        return (upkeepNeeded, "0x0"); // can we comment this out?
    }

    /**
     * @dev Once `checkUpkeep` is returning `true`, this function is called
     * and it kicks off a Chainlink VRF call to get a random winner.
     */
    function performUpkeep(
        bytes calldata /* performData */
    ) external override {
        (bool upkeepNeeded, ) = checkUpkeep("");
        // require(upkeepNeeded, "Upkeep not needed");
        if (!upkeepNeeded) {
            revert Raffle__UpkeepNotNeeded(
                address(this).balance,
                s_players.length,
                uint256(s_raffleState)
            );
        }
        s_raffleState = RaffleState.CALCULATING;
        uint256 requestId = i_vrfCoordinator.requestRandomWords(
            i_gasLane,
            i_subscriptionId,
            REQUEST_CONFIRMATIONS,
            i_callbackGasLimit,
            NUM_WORDS
        );
        // Quiz... is this redundant?
        emit RequestedRaffleWinner(requestId);
    }

I got these errors back

 1) Raffle uint test
       checkUpKeep
         returns false if people havent't sent any ETH yet:
     TypeError: raffle.callStatic.checkUpKeep is not a function

 1) Raffle uint test
       checkUpKeep
         returns false if raffle isn't open:
     TypeError: raffle.performUpKeep is not a function

hope someone can help me to fix the error, thanks in advance

Here is your error

await raffle.performUpKeep([]) //this will also works: ("0x")
const raffleState = await raffle.callStatic.checkUpKeep([])

These should be:

await raffle.performUpkeep([]) //this will also works: ("0x")
const raffleState = await raffle.callStatic.checkUpkeep([])
