describe('UserService', () => {
  let service: UserService;
  let envServiceSpy: SpyObj<EnvService>;
  let userApiService: SpyObj<UserApiService>;
  let usersMock = [
    {id: 1, name: 'Walter White', bestQuote: 'I am the one who knocks.'},
    {id: 2, name: 'Jesse Pinkman', bestQuote: 'Yeah, bitch! MAGNETS!'},
  ];
  let envMock = {
    apiUrl: 'http://example.com',
  };
 
  beforeEach(() => {
    // It is a good idea to re-initiate the spy instance after each run so you do not face any weird side-effects.
    // That way you also do not need to call `mySpy = TestBed.inject(MyService);`
    envServiceSpy = createSpyObj('EnvService', ['load']);
    envServiceSpy.load.and.returnValue(of(envMock))
 
    userApiService = createSpyObj('UserApiService', ['getUsers'], ['rootUrl']);
    userApiService.getUsers.and.returnValue(of(usersMock));
 
    TestBed.configureTestingModule({
      providers: [
        UserService,
        {provide: EnvService, useValue: envServiceSpy},
        {provide: UserApiService, useValue: userApiService},
      ],
    });
 
    service = TestBed.inject(UserService);
  });
 
  it('should be created', () => {
    expect(service).toBeTruthy();
  });
 
  it('should set rootUrl for userApiService on init', () => {
    // Considering the `constructor()` did run already due to our initialization in `beforeEach()`
    // we can just assert on our expectations
    expect(envServiceSpy.load).toHaveBeenCalled();
    expect(userApiService.rootUrl).toEqual('http://example.com');
  });
 
  // Here we test, that the `getUserList()` method in fact mapped
  // the (mocked) response from `getUsers()` properly
  it('should retrieve user list ', (done) => {
    service.getUserList().subscribe((userList) => {
      expect(userList).toEqual(usersMock);
      expect(userApiService.getUsers).toHaveBeenCalled();
      done();
    }, done.fail);
  });
});

Mais celui retourne l'erreur suivante :
Test should set rootUrl for userApiService on init' :
Error: Expected spy EnvService.load to have been called.,
Error: Expected undefined to equal 'api'.

Test should return value from observable :
service.getUserList() is not a function

Voici mon service à tester :

export class UserService {
  private env: EnvConfiguration;
 
  constructor(private userApiService: UserApiService, private envService: EnvService) {
    this.envService.load().subscribe(env => {
      this.env = env;
    });
 
    this.userApiService.rootUrl = this.env.apiUrl;
  }
 
  getUserList(): Observable<User[]> {
    return this.userApiService.getUsers().pipe(
      map(result => result),
      catchError(err => { return throwError(err);
      })
    );
  }
}

Je vois pas ou est le problème
