修復我的測試的事件聲明

我會試著把它簡單化。這是我的契約程式碼：

pragma solidity ^0.5.0;

contract Lottery {
   address public manager;
   address[] public players;
   event Deposit(address _from, uint value);

   constructor() public {
       manager = msg.sender;
   }

   function enter() public payable {
       require(msg.value > .01 ether, 'Not enough ether');
       players.push(msg.sender);
   }

   function numberPlayers() public view returns(uint) {
       return players.length;
   }
}

這是我的測試程式碼：

const lottery = artifacts.require('Lottery');

contract('Lottery', accounts => {
   let instance;

   beforeEach( async () => {
       instance = await lottery.deployed();
   });

   it('should have as manager the account which deployed', async () => {
       const manager = await instance.manager.call();

       assert.equal(manager, accounts[0]);
   });

   it('should create a player if the player send some ether', async () => {
       const payment = web3.utils.toWei("0.02", "ether");
       await instance.enter.sendTransaction({from: accounts[1], value: payment});
       const numberPlayers = await instance.numberPlayers.call();
       const player = await instance.players(numberPlayers - 1);

       assert.equal(player, accounts[1]);
   })
});

一切正常，但如果我像這樣在第 6 行評論存款事件：

pragma solidity ^0.5.0;

contract Lottery {
   address public manager;
   address[] public players;
   // event Deposit(address _from, uint value);

   constructor() public {
       manager = msg.sender;
   }

   function enter() public payable {
       require(msg.value > .01 ether, 'Not enough ether');
       players.push(msg.sender);
   }

   function numberPlayers() public view returns(uint) {
       return players.length;
   }
}

我收到下一個錯誤：

1) Contract: Lottery
      should create a player if the player send some ether:
    Error: Invalid number of parameters for "enter". Got 1 expected 2!

     at process._tickCallback (internal/process/next_tick.js:68:7)

我是solidity 的新手，所以我不知道我是否做錯了什麼，或者我是否在solidity 編譯器的0.5 版中遇到了錯誤。

這些是我的環境的版本：

Truffle v5.0.15 (core: 5.0.15)
Solidity v0.5.0 (solc-js)
Node v10.15.3
Web3.js v1.0.0-beta.37

非常感謝大家的時間

我註釋掉了這個Deposit事件然後跑了truffle test --network develop。結果很好：

 2 passing (143ms)

這很可能是一些奇怪的松露怪癖——它們經常發生。請嘗試刪除您的build目錄並再次執行測試。
