Question

假设我想测试一个用户登录控制器，该控制器通过SMS与Twilio发送登录代码。我应该如何设置测试，以便我可以模拟Twilio并查看它发回的代码。我的方法是代理twilio客户端对象并使用sinon监视它，但我认为我没有完全正确。

controller user.js

var smsClient = new twilio.RestClient(config.get('twilio_account_sid'), config.get('twilio_auth_token'));

module.exports = {
  checkCode: function(phone){
        var code = getNewCode();
        smsClient.sms.messages.create({
            from: config.get('twilio_phone_number'),
            to: phone,
            body: 'Your code :' + code
        }, callback);
  }
}

测试文件

var twilioMock = //what goes here??
var smsSpy = sinon.spy(twilioMock.sms.messages, 'create');
var User = proxyquire('../models/user', { 'mongoose': mongooseMock, 'smsClient': twilioMock }); 

... some describe and it statements ...
twilioMock.sms.messages.should.have.been.calledOnce()  //this is where I don't know what I should be checking

// or is this the right way? 
//smsSpy.should.have.been.calledOnce()

I am answering this very late but this might help someone.

I haven't used proxywire but it seems very similar to rewire (just by looking at your code). You should try the following:

var twilioMock = new twilio.RestClient(config.get('twilio_account_sid'), config.get('twilio_auth_token'));

I am more used to rewire. npm i rewire --save-dev. Using rewire you may try the following: (concept remains the same)

In your test:

var rewire = require('rewire');
var twilioMock = new twilio.RestClient(config.get('twilio_account_sid'), config.get('twilio_auth_token'));
var userController = rewire('./path_to_user.js') // notice use of rewire

beforeEach(function(){
    this.smsClient = twilioMock; // `this` is available within your tests
    userController.__set__('smsClient', this.smsClient);
});

it('should something', sinon.test(function(){
    var smsSpy = this.spy(this.smsClient.sms.messages, 'create');
}));

如何在单元测试中使用sinon / proxyquire或node.js中的依赖注入来模拟twilio
