Error on latest version on Jest (23.5.0)

See original GitHub issue

Here’s a checklist you can use to make sure your issue can be more easily resolved:

  • Check against the latest
  • Include a link to the example application source code
  • Paste into this issue the exact error messages messages you’re seeing

Whenever I run my tests with Jest version 21.2.1 everything works fine, but when I install Jest version 23.5.0 I receive the following error:

Error: expect(jest.fn())[.not].toHaveBeenCalledWith()
jest.fn() value must be a mock function or spy.
Received:  function: [Function getItem]

i.e. localStorage.getItem is not being mocked out

I’m on the latest version of jest-localstorage-mock (2.2.0) and my test setup file looks as follows:

import { configure } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';
import 'jest-localstorage-mock';

configure({ adapter: new Adapter() });

beforeEach(() => {

It seems that upgrading to Jest 22.0.0 or beyond causes the issue
