reason of error [FAIL. Reason: log != expected log]

contract RaffleTest is Test {
 /** */
 event EnterRaffle(address indexed player);

 function testEmitsEventOnEntrance() public {
 // Arrange
 vm.prank(PLAYER);
 // Act / Assert
 vm.expectEmit(true, false, false, false, address(raffle));
 emit EnterRaffle(PLAYER);
 raffle.enterRaffle{value: entranceFee}();
 }
}

contract Raffle is VRFConsumerBaseV2 {
 /**Event */
 event EnterRaffle(address player);
 function enterRaffle() public payable {
 s_players.push(payable(msg.sender));
 emit EnterRaffle(msg.sender);
 }
}

when run the code above with forge test –match-test testEmitsEventOnEntrance

the test will fail and throw alarm like this

Suite result: FAILED. 0 passed; 1 failed; 0 skipped; finished in 6.44ms (506.96µs CPU time)

 

the reason is that event in RaffleTest is

event EnterRaffle(address indexed player);

event in Raffle is

event EnterRaffle(address player);

 

this two event with indexed param and without indexed param was considered as different events.

so i remove the indexed and then pass the test case.
