})

On running the above test , i am getting the error .

      + expected - actual

      -Transaction NOT reverted.

@ImAnshuJoshi Make sure you have reset the variables inside fulfillRandomWords function because here

await expect(raffle.getPlayer(0)).to.be.reverted

you are expecting a revert. But it looks like players' array still returns the address on index 0.

[ImAnshuJoshi]

 function fulfillRandomWords(uint256 /*requestId*/ , uint256[] memory randomWords) internal override {
        //randomwords is going to be of size randomwords 1 
        //uint256 will be our randomNum
        uint256 indexOfWinner = randomWords[0] % s_players.length;
        address payable recentWinner = s_players[indexOfWinner];
        s_recentWinner = recentWinner;
        s_players = new address payable[](0);
        s_raffleState = RaffleState.OPEN;
        s_lastTimeStamp = block.timestamp;
        (bool success , ) = recentWinner.call{value : address(this).balance}("");

        if(!success){
            revert Raffle_TransferFail();
        }
        emit WinnerPicked(s_recentWinner);
    }

Yes , i have reset the variables and now getting this error .

@ImAnshuJoshi this is I think the assertion of balance, you are comparing the starting balance of account 1 with the winner balance of account 2.

Yea , missed that thing , thanks for the help
