proxyquire 错误：ENOENT：没有这样的文件或目录，scandir

Question

Hello I am new to testing with mocha/chai/sinon and sequelize-test-helpers

Trying to use proxyquire to override the require but having issues

Getting this following error about the path:

Error: ENOENT: no such file or directory, scandir 'C:<local-directories-path>\ecommerce-pern-app\server\src\models'

I dont get why there is a src folder when I don't have a src folder at all I am using the proxyquire in the test file and its path is from the server directory would be:

server/specs/services/user-service.spec.js

"use strict";
const chai = require('chai');
const {match, stub, resetHistory, spy} = require('sinon');
const proxyquire = require('proxyquire');
const path = require('path');
const service = path.resolve('./services/userService.js')
var sinonChai = require("sinon-chai");
chai.should();
chai.use(sinonChai);

console.log(service)

const {makeMockModels, sequelize, dataTypes,} = require('sequelize-test-helpers');

describe('Idea Controller', function () {

  const uid = '6a88e9b5-33a2-403f-ac3d-e86413ac101d'
  const data = {
    email: 'testface@test.com',
    password: '123456',
    is_admin: false,
    first_name: 'Testy',
    last_name: 'McTestface', 
    google_id: null,
    facebook_id: null
  }

    describe('findAll()', function () {
        it('Success case ', function () {

            const mockResponse = () => {
                const res = {};
                res.json = stub().returns(res);
                return res;
            };

            let res = mockResponse();

            const User = {findAll: stub()};
            const mockModels = makeMockModels({User});

            Idea.findAll.resolves(data);

            const UserService = proxyquire(service, {
              "save": {}
            });

            UserService.findAll({}, res);

            Idea.findAll.should.have.been.called; // passes
            res.json.should.have.been.called; //fails
        });
    })
});

In the above code I am using the proxyquire like this:

const proxyquire = require('proxyquire');
const path = require('path');
const service = path.resolve('./services/userService.js')
const {makeMockModel} = require('sequelize-test-helpers');

            const mockModels = makeMockModels({User});

            const UserService = proxyquire(service, {
              "../models": mockModels
            });

As I am trying to use the path to find the server/service/userService.js file which is relatively located from the test file at ../../services/userService.js . I have got this bug that there is src folder there when I do not have a src directory at all even!

As the bug is saying:

Error: ENOENT: no such file or directory, scandir 'C:<local-directories-path>\ecommerce-pern-app\server\src\models'

Whatever I try about file path is not working I tried path.resolve, path.join and directly typing the path into it as like ../../services/userService.js

here is the server/services/userService.js

const Models = require('../models');
const { User } = Models;

const save = async ({ id, ...data }) => {
  const user = await User.findOne({ where: { uid: id } })
  if (user) return await user.update(data)
  return null
}


module.exports = save;

I just want the path to with proxyquire to work

What is this \\src\\models path from the error, I dont have a src/models path route at all!

Answer 1

This is a quote from sequelize-test-helpers's readme .

As a convenience, makeMockModels will automatically populate your mockModels with mocks of all of the models defined in your src/models folder (or if you have a .sequelizerc file it will look for the models-path in that). Simply override any of the specific models you need to do stuff with.

So you need to provide .sequelizerc file and define models-path .
