Angular ActiveRoute test problem z przekazaniem param

siema. Mam problem z wstrzyknięciem do testów w angularze ActiveRoute z parametrami.

describe('ReportEditComponent', () => {

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [
        ReportEditComponent,
      ],
      imports: [
        FormsModule, ReactiveFormsModule,
        AppMaterialModule, RouterTestingModule
      ],
      providers: [
        {
          provide: ActivatedRoute, useValue: {
            paramMap: Observable.of(convertToParamMap({date: 'luty 2016' }))
          }
        }
      ]
    })
    .compileComponents();
  }));


  it('should get correct params', () => {
    const fixture = TestBed.createComponent(ReportEditComponent);
    const component = fixture.componentInstance;
    component.initCurrentDate();
  });
});

a w componencie metoda initCurrentDate

  initCurrentDate() {
    const param = this.route.snapshot.paramMap.get('date');
    const current = param.split(/\s/);
    this.currentMonth = current[0];
    this.currentYear = +current[1];
  }

jak odpalam test ukazuje mi się cos takiego this.route.snapshot is undefined ?
jak rozwiązać ten problem
