角度測試錯誤：無法讀取未定義的屬性「訂閱」在新的RouterLinkWithHref

Question

我不明白我在做什麼錯，我沒有找到任何鏈接RouterLinkWithHref任何測試錯誤，此外我'米不使用RouterLinkWithHref任何地方，據我所知：/

誰能幫我這個：

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

    const mockRouter = { 
    navigate: jasmine.createSpy('navigate') 
    }; 
    const mockCustomCardService = { 
    getItemDeliveryDate:() => Observable.empty(), 
    emitItemChanges:() => Observable.empty(), 
    }; 
    const mockActivatedRoute = { snapshot: {} }; 
    const mockPageDataService = {}; 
    const mockUserService = {}; 

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

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

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

});

您應該刪除您的路由嘲笑，因爲你（mockRouter，mockActivatedRoute）已經進口RouterTestingModule，這樣的事情：

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(); 
    }); 

});
