在 Javascript 中测试 onlyOwner 函数

Question

我的智能合约中出现这种情况：

address[] public allowedUsers;

function allowUser(address _newUser) public onlyOwner {
   allowedUser.push(_newUser);
}

我正在使用 truffle 和他的测试套件然后我写了这个案例，失败了可能是因为我没有以正确的方式使用唯一的所有者方法：

const MyContract = artifacts.require("../contracts/MyContract.sol");

contract("MyContract", accounts => {
    it("should deploy the contract and allow the user", async () => {
        const contract = await MyContract.deployed();

        const account = accounts[0];
        const owner = await contract.owner.call()

        await contract.allowUser(account).call({ from: owner });

        const allowedUser = contract.allowedUser.call(0);

        assert.equal(whitelistedUser, account, 'new user is not allowed');
    })
});

有人可以帮助我吗？谢谢大家！

假设你在合约中正确设置了owner，在合约中为owner写一个getter：

function getContractOwner() public view returns (address)
  {
    return owner;
  }

在test.js

contract("MyContract", accounts => {
     let _contract = null
     let currentOwner=null

    before(async () => {
      _contract = await MyContract.deployed();
      currentOwner = await _contract.getContractOwner()          
    })    
    it("should deploy the contract and allow the user", async () => {
        const account = accounts[0];
        await contract.allowUser(account, {from: currentOwner});
        // I assume this is retrieving data from a mapping
        const allowedUser = _contract.allowedUser.call(0);
        assert.equal(whitelistedUser, account, 'new user is not allowed');
    })
});
