I want to test this very simple function with jest and ts-jest.
I am using es modules.

export const tobetested = async () => {
  const targetUri = await getFunctionUrl('presaveJob');
  console.log(targetUri);
};

Function getFunctionUrl is placed on the same file and it’s

export async function getFunctionUrl(name: string, location = 'us-central1') {
  if (!auth) {
    auth = new GoogleAuth({
      scopes: 'https://www.googleapis.com/auth/cloud-platform',
    });
  }
  const projectId = await auth.getProjectId();
  const url =
    'https://cloudfunctions.googleapis.com/v2beta/' +
    `projects/${projectId}/locations/${location}/functions/${name}`;

  const client = await auth.getClient();
  const res = await client.request({ url });
  // @ts-ignore
  const uri = res.data?.serviceConfig?.uri;
  if (!uri) {
    throw new Error(`Unable to retrieve uri for function at ${url}`);
  }
  return uri;
}

Then in the test file

import { test, jest } from '@jest/globals';
import * as queues from '../queues';

test('Returns correct value', async () => {
  jest.spyOn(queues, 'getFunctionUrl').mockResolvedValue('sample string');

  await queues.tobetested();
});

The problem is that from the output i see it’s called the real function and not the mocked one.

Where am I wrong?
Thanks
