openzeppelin批量测试Solidity合约

openzeppelin是用于Solidity合约进行审计、代码安全测试的库，其中test-environment、test-helpers使用起来非常方便。下面，介绍对ERC20GuDingToken.sol、ERC20XiaoHuiToken.sol这2个合约的批量测试。

1、创建工程onecoin

1.1 创建工程和文件夹

## 1、创建工程
mkdir onecoin
cd onecoin
npm init -y
truffle init## 2、创建文件夹
mkdir -p test/ERC20
mkdir -p test/inc
mkdir -p contracts/ERC20
mkdir script

1.2 修改package.json

a) 修改onecoin/package.json文件，如下：

{"name": "onecoin","version": "1.0.0","description": "","main": "","directories": {"test": "test"},"scripts": {"test": "node script/test.js","compile": "truffle compile","ganache": "ganache-cli -e 1000","migrate": "truffle migrate","mocha": "mocha --exit --recursive"},"mocha": {"timeout": 100000,"useColors": true,"comment": "这里是彩蛋:下面这一行改成nyan然后再运行npm run test试一下","reporter": "spec"},"keywords": [],"author": "","license": "ISC","dependencies": {"@openzeppelin/contracts": "^2.5.1","@truffle/debug-utils": "^5.1.17","@truffle/hdwallet-provider": "^1.5.0","bip39": "^3.0.4","ethers": "^5.4.7","inquirer": "^8.1.5","web3": "^1.6.0"},"devDependencies": {"@openzeppelin/test-environment": "^0.1.9","@openzeppelin/test-helpers": "^0.5.13","chai": "^4.3.4","eth-gas-reporter": "^0.2.22","mocha": "^9.1.2","@babel/core": "^7.15.5","@babel/preset-env": "^7.15.6"}
}

b) 安装依赖包

npm config set registry https://registry.npm.taobao.org
npm install

1.3 修改truffle-config.js

修改后的truffle-config.js如下：


module.exports = {networks: {// Useful for testing. The `development` name is special - truffle uses it by default// if it's defined here and no other network is specified at the command line.// You should run a client (like ganache-cli, geth or parity) in a separate terminal// tab if you use this network and you must also set the `host`, `port` and `network_id`// options below to some value.//development: {host: "127.0.0.1",     // Localhost (default: none)port: 8545,            // Standard Ethereum port (default: none)network_id: "*",       // Any network (default: none)},// Another network with more advanced options...// advanced: {// port: 8777,             // Custom port// network_id: 1342,       // Custom network// gas: 8500000,           // Gas sent with each transaction (default: ~6700000)// gasPrice: 20000000000,  // 20 gwei (in wei) (default: 100 gwei)// from: <address>,        // Account to send txs from (default: accounts[0])// websocket: true        // Enable EventEmitter interface for web3 (default: false)// },// Useful for deploying to a public network.// NB: It's important to wrap the provider as a function.// ropsten: {// provider: () => new HDWalletProvider(mnemonic, `https://ropsten.infura.io/v3/YOUR-PROJECT-ID`),// network_id: 3,       // Ropsten's id// gas: 5500000,        // Ropsten has a lower block limit than mainnet// confirmations: 2,    // # of confs to wait between deployments. (default: 0)// timeoutBlocks: 200,  // # of blocks before a deployment times out  (minimum/default: 50)// skipDryRun: true     // Skip dry run before migrations? (default: false for public nets )// },// Useful for private networks// private: {// provider: () => new HDWalletProvider(mnemonic, `https://network.io`),// network_id: 2111,   // This network is yours, in the cloud.// production: true    // Treats this network as if it was a public net. (default: false)// }},// Set default mocha options here, use special reporters etc.mocha: {timeout: 300000,reporter: 'eth-gas-reporter',reporterOptions: { excludeContracts: ['Migrations'] }},// Configure your compilerscompilers: {solc: {version: "0.5.12",    // Fetch exact version from solc-bin (default: truffle's version)// docker: true,        // Use "0.5.1" you've installed locally with docker (default: false)// settings: {          // See the solidity docs for advice about optimization and evmVersion//  optimizer: {//    enabled: false,//    runs: 200//  },//  evmVersion: "byzantium"// }}},// Truffle DB is currently disabled by default; to enable it, change enabled:// false to enabled: true. The default storage location can also be// overridden by specifying the adapter settings, as shown in the commented code below.//// NOTE: It is not possible to migrate your contracts to truffle DB and you should// make a backup of your artifacts to a safe location before enabling this feature.//// After you backed up your artifacts you can utilize db by running migrate as follows: // $ truffle migrate --reset --compile-all//// db: {// enabled: false,// host: "127.0.0.1",// adapter: {//   name: "sqlite",//   settings: {//     directory: ".db"//   }// }// }
};

1.4 ERC20GuDingToken合约

路径: onecoin/contracts/ERC20GuDingToken.sol

pragma solidity >=0.4.21 <0.7.0;import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
import "@openzeppelin/contracts/token/ERC20/ERC20Detailed.sol";//固定总量Token
contract ERC20GuDingToken is ERC20,ERC20Detailed {constructor(string memory name,  //全称 string memory symbol,//简称 uint8 decimals,      //精度uint256 totalSupply  //总量 ) public ERC20Detailed(name,symbol,decimals) {_mint(msg.sender, totalSupply*(10**uint256(decimals)));}
}

1.5 ERC20XiaoHuiToken合约

路径: onecoin/contracts/ERC20XiaoHuiToken.sol

pragma solidity >=0.4.21 <0.7.0;import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

import "@openzeppelin/contracts/token/ERC20/ERC20Burnable.sol";contract ERC20XiaoHuiToken is ERC20,ERC20Detailed,ERC20Burnable {constructor(string memory name,   //全称string memory symbol, //简称uint8 decimals,       //精度uint256 totalSupply   //总量) public ERC20Detailed(name,symbol,decimals) {_mint(msg.sender,totalSupply*(10**uint256(decimals)));}
}

1.6 开启ganache

在 ganache里设置IP:127.0.0.1, 端口:8545，重启ganache，如图(1)所示：

// 2_deploy_ERC20GuDingToken.js

const ERC20GuDingToken = artifacts.require("ERC20GuDingToken");module.exports = function(deployer) {deployer.deploy(ERC20GuDingToken,"GuDingToken","GDT",18,80000);
};

b) ERC20XiaoHuiToken合约的部署脚本：onecoin/migrations/3_deploy_ERC20XiaoHuiToken.js
// 3_deploy_ERC20XiaoHuiToken.js

const ERC20XiaoHuiToken = artifacts.require("ERC20XiaoHuiToken");module.exports = function(deployer) {deployer.deploy(ERC20XiaoHuiToken,"XiaoHuiToken","XHT",18,80000);
};

1.8 在ganache里部署合约

cd onecoin

}

2.2 主菜单脚本

主菜单脚本，用于对选中指定的合约脚本进行测试，或者全部测试
路径: onecoin/script/test.js

const fs = require('fs');
var inquirer = require('inquirer');
const {spawn} = require('child_process');const contractDir = 'test/';
getFiles = async (path) => {const dir = await fs.readdirSync(path,'utf-8');let files = [{name:'全部测试', value:'all'}];dir.forEach(async (e1,index) => {let stat = fs.statSync(path + e1);if (e1 !== 'inc') {if (stat.isDirectory()) {let dirFiles = await fs.readdirSync(path+e1+'/','utf-8');dirFiles.forEach((sube1, index) => {files.push(e1 +'/'+sube1);})} else {files.push(e1);}}})return files;

3、进行测试

打开一个控制台终端，输入如下命令：

npm run test## 或者使用命令:
node scripts\test.js## 选中"全部测试" 表示测试contracts目录里的所有合约
## 选中"ERC20/ERC20GuDingToken.js" 表示测试ERC20GuDingToken合约
## 选中"ERC20/ERC20XiaoHuiToken.js" 表示测试ERC20XiaoHuiTokenn合约

图(3) 按上下方向键，选中要测试的合约

这里，选中“全部测试”一栏，效果如下：

由上可知，这2个合约，一共52测试案例，全部测试通过，耗时10s。
