Truffle-Test
成功編譯後嘗試執行松露測試我有這個錯誤:“未定義”的參數數量無效。得到 0 預期 1!
這是我的部署 hello js 文件
const hello = artifacts.require('./HelloWorld'); module.exports = function(deployer){ deployer.deploy(hello); };
這是契約程式碼
pragma solidity^0.5.16; contract HelloWorld { string private name; mapping (address => uint256) public balance; constructor(string memory _name) public { name = _name; balance[msg.sender] = 1000; } function getName() public view returns (string memory) { return name; } function setName(string memory _name) public { name = _name; } }
部署 HelloWorld 時必須傳遞一個字元串,因為它的建構子接收一個參數。
constructor(string memory _name) public {
例如它應該看起來像這樣
const hello = artifacts.require('./HelloWorld'); module.exports = function(deployer){ deployer.deploy(hello, "zzzz"); };
