Mocking window.Twitch oject in tets

Extensions

I leave here the config urationthat AlbericoD posted earlier in text format, just in case for another dev need to copy it.

import Enzyme, { shallow, render, mount } from 'enzyme';
import toJson from 'enzyme-to-json';
import Adapter from 'enzyme-adapter-react-16';

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


global.toJson   = toJson;
global.shallow  = shallow;
global.render   = render;
global.mount    = mount;

if(typeof windows.Twitch === 'undefined') {
  Object.defineProperty(window, 'Twitch', {
    value: {
      ext: {
        onAuthorized: jest.fn(),
        listen: jest.fn(),
        onContext: jest.fn(),
        bits: {
          getProducts: jest.fn(),
          onTransactionCancelled: jest.fn(),
          onTransactionComplete: jest.fn(),
          setUseLoopback: jest.fn(),
          showBitsBalance: jest.fn(),
          useBits: jest.fn()
        }
      }
    }, 
    writable: true
  })
}
