  let fixture: ComponentFixture<NotFoundComponent>;

  beforeEach(async () => {
    await TestBed.configureTestingModule({
      declarations: [NotFoundComponent],
    }).compileComponents();
  });

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