Nodejs嘲笑一个方法
我想做一个getDbmodel方法的存根。
它是在basemodel.js中定义的
import Sequelize from 'sequelize'; import db from '../../config/database'; let instance = null; class Database { static getDbmodel = () => { if (instance != null) { return instance; } instance = new Sequelize(db.default.database, db.default.username, db.default.password, { host: db.default.host, dialect: db.default.dialect, define: { timestamps: false, // true by default }, pool: { max: db.default.maxConnections, min: db.default.minConnections, idle: db.default.idleTimeoutMillis, timezone: '+00:00', }, }); console.log('inside basemodel'); return instance; } } export { Database as default }; // ======================================================== // src/Libraries/ABTest.js import ABTestStorage from '../Storage/ABTest'; class ABTestLib { getABTestById = id => ABTestStorage.getABTestById(id); getABTests = () => ABTestStorage.getABTests().then() .catch(err => console.log(err)) save = abtestObj => ABTestStorage.saveABTest(abtestObj).then() .catch(err => console.log(err)) put = abtestObj => ABTestStorage.updateABTest(abtestObj) .then() .catch(err => console.log(err)) delete = id => ABTestStorage.destroyABTestById(id).then() .catch(err => console.log(err)) } export default ABTestLib;
abtest.js导入abimportabtest.js basemodel 。
这是我的testing文件：
import chai from 'chai'; const SequelizeMock = require('sequelize-mock'); var proxyquire = require('proxyquire'); describe('Libraries/ABTest.js', () => { before(function () { let instance = null; class Database { static getDbmodel = () => { if (instance != null) { return instance; } instance = new SequelizeMock(); console.log(instance); return instance; } } }); var stubs = { '../..src/Libraries/BaseModel': { getDbmodel: function () { console.log('3444e4'); if (instance != null) { console.log('1111'); return instance; } instance = new SequelizeMock(); console.log(instance); return instance; } } }; const ABTests = proxyquire('../../src/Libraries/ABTest', stubs); console.log(ABTests); const abtest = new ABTests.default(); it('get(1): should return response for a abtest', () => { abtest.getABTestById(1).then((res) => { chai.expect(res).to.be.an('object'); }); }); it('getAll() : should return response and status 200 for all abtests', () => { abtest.getABTests().then((res) => { chai.expect(res).to.be.an('object'); }); }); it('save() : should return response and status 200 for a abtest', () => { abtest.save({ id: '500', name: 'home', code: 'home', id_organization: '1', id_platform: '1', }).then((res) => { chai.expect(res).to.be.an('object'); }); }); it('put() : should return response and status 200 for a abtest', () => { abtest.put({ id: '2', }).then((res) => { chai.expect(res).to.be.an('object'); }); }); it('delete() : should return response and status 200 for a abtest', () => { abtest.delete({ id: '111', }).then((res) => { chai.expect(res).to.be.an('object'); }); }); });
为什么它总是进入basemodels gedbmodel而不是gedbmodel ？
我想模拟getdbmodel方法。
尝试在proxyquire中使用noCallThru函数： proxyquire.noCallThru().load('../../src/Libraries/ABTest', stubs).default
