[Shiv2116]

hello everyone

function testRevertsIfCollateralZero() public{
        vm.prank(USER);
        ERC20Mock(weth).approve(address(engine),AMOUNT_COLLATERAL); 

        vm.expectRevert(DSCEngine.DSCEngine__ZeroAmount.selector);
        engine.depositCollateral(weth, 0);
        vm.stopPrank();
    }
