Unit testing: How do I mock the innerWidth property on the window object with Angular + Jasmine?

I want to write a unit test which expects a variable to contain a specific value depending on the innerWidth of the window.

In my unit test, I use window.innerWidth = 1000;. However, I receive an error which says Cannot assign to 'innerWidth' because it is a read-only property..

Code (home.component.spec.ts):

  xit('should order the cards in the appropriate order on desktop', () => {
    spyOn(component, 'reOrderCards');
    window.innerWidth = 1000;
  })

Is there any way to mock the innerWidth property?
