? ? openzeppelin是用于Solidity合約進行審計、代碼安全測驗的庫，其中test-environment、test-helpers使用起來非常方便，下面，介紹對ERC20GuDingToken.sol、ERC20XiaoHuiToken.sol這2個合約的批量測驗，
1、 創建工程onecoin
1.1 創建工程和檔案夾
## 1、創建工程
mkdir onecoin
cd onecoin
npm init -y
truffle init
## 2、創建檔案夾
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檔案，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": "這里是彩蛋:下面這一行改成nyan然后再運行npm run test試一下",
"reporter": "spec"
},
"keywords": [],

"mocha": "^9.1.2",

"@babel/preset-env": "^7.15.6"
}
}
? ? b) 安裝依賴包
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 compilers
compilers: {
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"
// }
// }
// }
};

}
1.6 開啟ganache
? ? 在 ganache里設定IP:127.0.0.1, 埠:8545，重啟ganache，如圖(1)所示：
1.7 撰寫部署腳本
? ? a) ERC20GuDingToken合約的部署腳本：onecoin/migrations/2_deploy_ERC20GuDingToken.js
// 2_deploy_ERC20GuDingToken.js
const ERC20GuDingToken = artifacts.require("ERC20GuDingToken");
module.exports = function(deployer) {
deployer.deploy(ERC20GuDingToken,
"GuDingToken","GDT",18,80000);
};
? ? b) ERC20XiaoHuiToken合約的部署腳本：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里部署合約
cd onecoin
truffle console
compile
migrate
