How do I stub non object function using sinon

Question

I have a non object function

on getConfig.js

export default function () {
 /** do something **/
  return {
    appConfig: { status: true } 
    }
}

and under my main file

import getConfig from './getConfig';

export default function() {
 const { appConfig } = getConfig();
 
 if(appConfig.status) {
   console.log("do the right thing");
   else {
   console.log("do other things")
   }
  }
 }

How do I mock the getConfig function using sinon stub or mock methods? or is there any better way to set appConfig.status property to make true or false?

I would like to do the following but its not working

import getConfig from './getConfig';
import main from './main';

test('should status to be true', () => {
  
  sinon.stub(getConfig).callsFake(sinon.fake.returns({status:true});
  expect(main()).toBe('to do the right thing')
}

Answer 1

Ok I found another alternate solution using just JEST

jest.mock('./getConfig', () => (
 jest.fn()
 .mockReturnValueOnce({ appConfig: { status: true }})
 .mockReturnValueOnce({ appConfig: { status: false }})
))

//The getConfig get replaced with the above mock function

So the solution looks like

import main from './main';

jest.mock('./getConfig', () => (
 jest.fn()
 .mockReturnValueOnce({ appConfig: { status: true }})
 .mockReturnValueOnce({ appConfig: { status: false }})
))


test('should status to be true', () => {
  expect(main()).toBe('to do the right thing')
  expect(main()).toBe('to do the other things')
}
