test目录，storage_test.js

const BN = require("bn.js");
module.exports = async function (callback) {try {let frac = new BN(200);let SimpleStorage = artifacts.require("SimpleStorage");let tokenInstance = await SimpleStorage.deployed();await tokenInstance.set(frac);let data = await  tokenInstance.get();console.log('data =' + JSON.stringify(data));callback()} catch (e) {callback(e);}
};
