Window.provider.ts file

import {InjectionToken, FactoryProvider} from '@angular/core';

export const WINDOW = new InjectionToken<Window>('window');

const windowProvider: FactoryProvider = {provide: WINDOW,useFactory: () => window,};

export const WINDOW_PROVIDERS = [windowProvider];

Window.service.ts file

import {Injectable, Inject} from '@angular/core';
import {WINDOW} from './window.provider';

@Injectable({
  providedIn: 'root',
})
export class WindowService {
  constructor(@Inject(WINDOW) public window: Window) {}
}

spec.ts file

providers: [
        WINDOW_PROVIDERS, WindowService]

beforeEach(() => {
    fixture = TestBed.createComponent(FlightIndexComponent);
    component = fixture.componentInstance;
    fixture.detectChanges();
  });

  it('should create', () => {
    // const service: WindowService = TestBed.get(WindowService);
    expect(component).toBeTruthy();
  });

You need to provide WINDOW in your test:

providers:[
        {
          provide: WINDOW,
          useValue: window,
        },
]
