Question

如何使用proxyquire和sinon存储以下模块：

var email = require("emailjs").server.connect.send();

我执行了以下操作，但它无效，因为当我尝试在send()内触发错误时，它仍会发送电子邮件。

sendMailStub = sinon.stub(email, "send");    
testedModule = proxyquire('../index.js', {
                'email': {
                    'server': {
                        'send': sendMailStub
                        }
                    }
            });

还尝试过：

testedModule = proxyquire('../index.js', {
            email: {send: sendMailStub}
        });

这是迄今为止的全面测试，但未通过：

var chai = require('chai');
var sinonChai = require("sinon-chai");
var sinon = require('sinon');
chai.use(sinonChai);
var proxyquire = require('proxyquire');
var testedModule;
var expect = chai.expect;

让我们首先使用其documentation

修复您描述的emailjs所在的行

require("emailjs").server.connect({
  /* Required server options */
}).send(function (err, message) {
  // This a function with a callback node convention signature
});

connect是一个函数，应该接收一些参数，而且send不会返回任何内容，基本上都会调用回调

Proxyquire需要使用相同的模块名称，因此email应为emailjs，另一方面，您错误地在proxiquire中分配存根，它应该< / p>

connectStub = sinon.stub().returns(sendStub);
sendMailStub = sinon.stub(email, "send");    
testedModule = proxyquire('../index.js', {
            'emailjs': {
                'server': {
                    'connect': connectStub
                }
        });

与proxyquire一起订货
