无法在摩卡中测试数量转移的实效性。但是手动测试运行良好

Question

我的合同

pragma solidity ^0.8.13;

contract Escrow{
    address payable public dev;
    address public website;
    address public customer;
    uint public amount;

    constructor( address payable _dev, address _customer,uint _amount){
        dev = _dev;
        website = msg.sender;
        customer = _customer;
        amount = _amount;

    }

    function deposit() payable public{
        require(msg.sender == customer, "Only customer can add money");
        require(address(this).balance <= amount, "Money can not exceed given amount");
    }

    function sendMoney() public{
        dev.transfer(amount);
    }

}

部署脚本

const Escrow = artifacts.require("Escrow");

module.exports = function (deployer, network, accounts) {
  deployer.deploy(Escrow, accounts[1],accounts[2], 1000);
};

当我在混合网站上做手工测试时，它很好用。但是在测试sendMoney函数时，它是抛出错误

const Escrow = artifacts.require("Escrow");

contract("Escrow", (accounts) => {
  let escrow = null;
  const [website, dev, customer] = accounts;
  before(async () => {
    escrow = await Escrow.deployed();
  }); 

  it("Check money send", async ()=>{
    try{
      const prevDevBalance = web3.utils.toBN(await web3.eth.getBalance(dev))
      await escrow.sendMoney({from:accounts[0]})
      const newDevBalance = web3.utils.toBN(await web3.eth.getBalance(dev))
      assert(true)
      return
    }catch(e){
      assert(false)
      console.log("ERRORR",e)
    }
  }) 
});

有时测试是成功的，但90%的时间抛出这个问题。

       Check money send:
     Uncaught AssertionError: Unspecified AssertionError

您似乎没有初始化契约，它的构造函数需要3个参数address payable _dev, address _customer,uint _amount。

用这个来部署-

  before(async () => {
    escrow = await Escrow.new(dev, customer, "1");
  });
