错误：返回错误：处理事务时 VM 异常：还原只有所有者可以调用此 function

Question

我正在尝试使用“松露测试”来测试这个合同，但它显示以下错误：

错误：返回错误：处理事务时 VM 异常：还原只有所有者可以调用此 function - - 给出的原因：只有所有者可以调用此 function。

游戏.sol

pragma solidity ^0.5.0;

contract Gaming {
    /* Our Online gaming contract */
    address public owner;
    bool public online;

    struct Player {
        uint wins;
        uint losses;
    }

    mapping (address => Player) public players;

    constructor() public payable {
        owner = msg.sender;
        online = true;
    }

    modifier isOwner() {
        require(msg.sender == owner, "Only owner can call this function");
        _;
    }

}

测试游戏.sol

pragma solidity ^0.5.0;

import "truffle/Assert.sol";
import "truffle/DeployedAddresses.sol";
import "../contracts/Gaming.sol";

contract TestGaming {
    uint public initialBalance = 10 ether;
    Gaming gaming;
    address owner;

    function beforeAll() public {
        gaming = Gaming(DeployedAddresses.Gaming());
        owner = gaming.owner();

    }

    function testWithdrawFunds() public {
        uint ownerBalanceBefore = owner.balance;
        gaming.withdrawFunds();
        uint ownerBalanceAfter = owner.balance;

        Assert.equal (initialBalance, ownerBalanceAfter - ownerBalanceBefore, "The owner's balance should have increased by 10 ether");
}

错误

Error: Returned error: VM Exception while processing transaction: revert only owner can call this function - - Reason given: Only owner can call this function.
