Протестируйте внедренную услугу с другой услугой в angular 5

Я пытаюсь протестировать службу, в которую внедрено другой сервис: Вот сервис, который я хочу протестировать: 

@Injectable()
export class LaunchDarklyService {
    private _ldClient: LDClient;
    _flags: LDFlagSet;
    flagChange: Subject<Object> = new Subject<Object>();
    userReady: boolean;
    private ldClientIsReady:boolean

constructor(private authService: AuthService) {
    this._flags = {};

    this._ldClient = initialize(environment.launchDarklyClientId, {
        key: environment.launchDarklySDKKey,
        anonymous: true
    });

    this._ldClient.waitForInitialization().then(()=> {this.ldClientIsReady = true})

    this._ldClient.on('change', flags => {
        this.updateFlags(flags);
    });

    this._ldClient.on('ready', () => {
        this.setFlags();
    });
}

Внедренный сервис: 

@Injectable()
export class AuthService {

  baseUrl = environment.authServiceBaseUrl;

  constructor(private http: HttpClient) {
  }

  logout() {
    this.removeToken();
  }

И вот мой файл .spe c .ts: 

fdescribe("launchDarklyService", () => {

  let user: User;
  let mockAuthService: AuthService;
  let mockLaunchDarklyService: LaunchDarklyService;

  beforeEach(() => {
user = {
  id: "024fe324-f4c9-4b7c-a5aa-d1c67cbb6baa",
  username: "Test",
  enabled: true,
  accountNonExpired: false,
  accountNonLocked: false,
  credentialsNonExpired: false,
  authorities: [],
  createDateTime: "",
  email: "",
  firstName: "Test",
  lastName: "Test",
  salesForceUserId: "",
  updateDateTime: ""
};

mockAuthService = jasmine.createSpyObj(["me"]);

TestBed.configureTestingModule({
  providers: [
    LaunchDarklyService,
    { provide: AuthService, useValue: mockAuthService }
  ]
});

mockLaunchDarklyService = TestBed.get(LaunchDarklyService);
mockAuthService = TestBed.get(AuthService);


 });

  fit('should be created', () => {
    expect(mockLaunchDarklyService).toBeTruthy();


 });

  fit('should identify the user', () => {

    mockLaunchDarklyService.identifyUser();

    mockAuthService.me().subscribe(res => {
    });

expect(mockAuthService.me).toHaveBeenCalled();
expect(mockLaunchDarklyService.userReady).toBe(true);
  });

Но когда я запускаю тест, результаты показывают мне следующую ошибку: 

ERROR: 'Cannot read property 'toPromise' of undefined'
ERROR LOG: 'Cannot read property 'toPromise' of undefined'

Я хотел бы знать, существует ли способ решить такой тест или мне нужно что-то изменить в службах.
