googleapis module issue with mocking single method

I’m using googleapis module which has so many apis and methods. I tried all the possible below thing, nothing working. Why the common approach for mocking is differentiating by modules.

My production code:

let google = require('googleapis');
const iam = google.iam('v1');

I want to mock iam method of googleapis module

Try 1:

jest.unmock('googleapis');
let google = require('googleapis');
google.iam = jest.fn().mockImplementation(function() {
  return { mock: 'mock' };
} );

Try 2:

jest.mock('googleapis', () => {
return jest.fn(() => { iam: 'mock' });
})

This allows mocking, but its working only if my production code is
const iam = google().iam;

Why these 2 ways not working.?

@popkutty I see. So just do the following and you’re settled 😉

jest.mock('googleapis', () => {
    return { iam: () => 'mock' };
});
