角度测试错误：无法在新的RouterLinkWithHref上读取未定义的属性“subscribe”

Question

我不知道我做错了什么，我没有找到 RouterLinkWithHref 的任何链接到测试中的任何错误，而且我没有在任何地方使用RouterLinkWithHref，就我而言知道：/

任何人都可以帮助我：

ID | Name | NumberofAnotherObjects

1  | abc  | 42
2  | def  | 56    
3  | xyz  | 592

您应该删除路由模拟（ mockRouter ， mockActivatedRoute ），因为您已导入 RouterTestingModule ，如下所示：

describe('AddItemComponent: ', () => {
  let cmp: AddItemComponent;
  let fixture: ComponentFixture<AddItemComponent>;
  let de: DebugElement;
  let el: HTMLElement;

  const mockCustomCardService = {
    getItemDeliveryDate: () => Observable.empty(),
    emitItemChanges: () => Observable.empty(),
  };
  const mockPageDataService = {};
  const mockUserService = {};

  beforeEach(() => {
    TestBed.configureTestingModule({
      declarations: [AddItemComponent],
      imports: [FormsModule, ReactiveFormsModule, SharedModule, TranslateModule.forRoot(), RouterTestingModule],
      providers: [
        SpinningService,
        FormBuilder,
        TranslateService,
        { provide: CustomItemService, useValue: mockCustomItemService },
        { provide: PageDataService, useValue: mockPageDataService },
        { provide: UserService, useValue: mockUserService }
      ],
      schemas: [NO_ERRORS_SCHEMA]
    });

    fixture = TestBed.createComponent(AddItemComponent);
    cmp = fixture.componentInstance;
    fixture.detectChanges();
  });

  it('Simple test', () => {
    expect(true).toBeTruthy();
  });

});
