使用Sinon模拟require（）函数

I'm trying to mock request-promise in a test using Sinon. As far as I can tell, Sinon mocks methods of objects, and yet request-promise simply returns a function. Is there any way to mock a single required function?

我正试图在使用Sinon的测试中模拟请求 - 承诺。据我所知,Sinon嘲笑对象的方法,但是request-promise只返回一个函数。有没有办法模拟一个必需的功能?

var rp = require('request-promise');
var User = require('../../models/user');

// this works
sinon.stub(User, 'message', function() {});

// This is what I'd like to do to request-promise
sinon.stub(rp, function() {});

I've also looked into mockrequire and proxyquire but I think they both run into similar issues.

我也看过mockrequire和proxyquire,但我认为他们都遇到了类似的问题。

I found a (sort of) solution here.

我在这里找到了一种(某种)解决方案。

Basically, you piggyback off of call (apply would also work):

基本上,你背负电话(申请也可以):

// models/user.js
var rp = require('request-promise');

var User = {
    save: function(data) {
        return rp.call(rp, {
            url: ...,
            data: data
        });
    }
}
module.exports = User;



// test/user.js
var rp = require('request-promise');
var User = require('../../models/user');

describe('User', function() {
    it('should check that save passes data through', function() {
        sinon.stub(rp, 'call', function(data) {
            // check data here
        });
        User.save({ foo: 'bar' });
    });
});

It gets the job done, although I'm not a fan of having to do rp.call everywhere, so I'm still holding out hope for a better solution.

它完成了工作,虽然我不喜欢在任何地方都做rp.call,所以我仍然希望有更好的解决方案。
