Si le component utilise la .value d'un contrôle, ajouter dans le mock de FormGroup:

  public form: FormGroup = new FormGroup({
    firstName: new FormControl(''),
  });

Positioner et maximiser le browser sur le deuxième écran lors de développement de tests :

await browser.driver
  .manage()
  .window()
  .setPosition(2400, 100);
 
await browser.driver
  .manage()
  .window()
  .maximize();

const video = require('./video');
 
test('plays video', () => {
  const spy = jest.spyOn(video, 'play');
  const isPlaying = video.play();
 
  expect(spy).toHaveBeenCalled();
  expect(isPlaying).toBe(true);
 
  spy.mockReset();
  spy.mockRestore();
});
