Unable to stub indirect improts

[sujeet-agrahari]

I have an app.js which imports routes and routes is exported from particular modules.

Below is the who picture.
app.js imports route load and route loader imports routes from a module, and that module imports the services and controller.

ap.js
- loaders
   - routes.js 
- components
   - auth
      auth.module.js
      auth.service.js
      auth.routes.js
      otp.service.js 

Below is the code that I tried.

/* eslint-disable no-unused-expressions */
const test = require('ava');
const request = require('supertest');
const sinon = require('sinon');
const { expect } = require('chai');
const proxyquire = require('proxyquire');
const app = require('../src/app');

test.before(async (t) => {
  const sendOtpStub = sinon.stub().resolves({});
  proxyquire('../src/components/auth/auth.module', {
    './otp.service': {
      doSendOtp: sendOtpStub,
    },
  });
  t.context.stubs = {
    sendOtpStub,
  };
  t.context.baseUrl = '/api/v1/auth';
  t.context.server = request(app);
});

test.after.always((t) => {
  delete require.cache[require.resolve('../src/app')]; // kills
});

test.serial('Send OTP', async (t) => {
  const { server, baseUrl, stubs } = t.context;
  const response = await server.get(`${baseUrl}/send-otp?phone=8576863491`)
    .expect(200);
  expect(stubs.sendOtpStub.calledOnce).to.be.true;
  expect(response).to.be.a('Object');
});

// test.serial('Login', async (t) => {

// })

Below error I am getting.

Send OTP

  tests\auth.test.js:25

   24:     .expect(200);
   25:   expect(sendOtpStub.calledOnce).to.be.true;
   26:   expect(response).to.be.a('Object');

  Rejected promise returned by test. Reason:

  AssertionError {
    actual: false,
    expected: true,
    message: 'expected false to be true',
    showDiff: true,
  }

  » tests/auth.test.js:25:39

Can someone explain if this is possible what I have trying to do with proxyquire?

What's the issue?

Hi, in order to further investigate your issue I'll need the complete code for all the modules in question. A simpler reproduction would be better.

It sounds like you're asking about replacing transitive dependencies, that's explained here:

@bendrucker Please see this https://github.com/sujeet-agrahari/node-express-clean-architecture.
In this case it's same as to stub doLogin or doRegister imported in auth module.

I don't see any otp.service require in here, but it sounds like you might be asking about global overrides, in which case my advice above would apply.
