Lesson 9: Events are not firing in unit test for localhost.

[sanjayojha]

while testing the following. I get error.

it("updates the raffle state and emits a requestId", async () => {
    await raffle.enterRaffle({ value: raffleEntranceFee });
    await network.provider.send("evm_increaseTime", [interval + 1]);
    await network.provider.request({ method: "evm_mine", params: [] }); 
    const transactipnResop = await raffle.performUpkeep("0x");
    const transactipnReceipt = await transactipnResop.wait();
    const raffleState = await raffle.getRaffleState();
    const reqstId = transactipnReceipt!.events![1].args!.requestId; 
    //^ this is type undefined if I assert the test. Its because `events` is missing.
    console.log(`----events----`);
    console.log(transactipnReceipt.logs);
    console.log(`----eventsends----`);

    //assert(reqstId.toNumber() > 0); 
    //assert.equal(raffleState.toString(), "1");
});

the console log output:

As we can see there is no event is fired in above log.

My Raffle.sol code

 event RequestRafflewinner(uint256 indexed requesetId);

//To pick a winner, used by chainlink keeper automatically.
    function performUpkeep(  bytes calldata /* performData */   ) external override { 
    (bool upkeepNeeded, ) = checkUpkeep("");

        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_CONFIRMATION,
            i_callbackGasLimit,
            NUM_WORDS
        );
        emit RequestRafflewinner(requestId);
    }

Never mind. I did a spelling error.

Instead of event RequestRafflewinner(uint256 indexed requesetId);
I should have
event RequestRafflewinner(uint256 indexed requestId);

Note the spelling of requestId.
