javascript - npm lint 上可观察到的 "source is deprecated"错误

Question

我收到“源已弃用:这是一个内部实现细节，请勿使用。”当我在下面的代码上运行命令 npm lint 时:

 set stream(source: Observable<any>) {
    this.source = source;
  }

如果我将其取出，它会满足 lint，但会破坏我的单元测试。这是为什么？

如果您正在测试效果，则需要更新方法。我已经使用 provideMockActions 进行了更改，该操作将是一个 let actions$: Observable;

fdescribe('PizzaEffects', () => { 让行动$:可观察的；； 让服务:服务； 让效果:PizzaEffects； const data = givenPizzaData();

    beforeEach(() => {
        TestBed.configureTestingModule({
            imports: [ApolloTestingModule],
            providers: [
                Service, 
                PizzaEffects, 
                Apollo, 
                // { provide: Actions, useFactory: getActions }, remove
                provideMockActions(() => actions$),
            ]
        });

        actions$ = TestBed.get(Actions);
        service = TestBed.get(Service);
        effects = TestBed.get(PizzaEffects);

        spyOn(service, 'loadData').and.returnValue(of(data));
    });

    describe('loadPizza', () => {
        it('should return a collection from LoadPizzaSuccess', () => {
            const action = new TriggerAction();
            const completion = new LoadPizzaSuccess(data);
            actions$ = hot('-a', { a: action });
            const expected = cold('-b', { b: completion });

            expect(effects.getPizzaEffect$).toBeObservable(expected);
        });
    });
});
