Lesson 9: Error while running Raffle__UpkeepNotNeeded while running Unit tests

[harshuo2]

I'm getting this error while running the unit tests for lesson 9, hardhat smart lottery:

1) Raffle Unit Tests
       performUpkeep
         reverts if upkeep is not needed:
     Error: VM Exception while processing transaction: reverted with custom error 'Raffle__UpkeepNotNeeded(0, 0, 0)'
    at Raffle.performUpkeep (contracts/Raffle.sol:129)

    at EthersProviderWrapper.send (node_modules/@nomiclabs/hardhat-ethers/src/internal/ethers-provider-wrapper.ts:13:20)

This is my code:

it("reverts if upkeep is not needed", async function () {
          await expect(await raffle.performUpkeep("0x")).to.be.reverted

My solidity code goes like:

if (!upkeepNeeded) {
      revert Raffle__UpkeepNotNeeded(
        address(this).balance,
        s_players.length,
        uint256(s_raffleState)
      );

Great formatted question. Right now, you're running await inside await expect, so you code is executing:

await raffle.performUpkeep("0x")

We don't want it to do await for performUpkeep to finish, so we just remove the await

await expect(raffle.performUpkeep("0x")).to.be.reverted
