与relativeTo一起使用时如何测试router.navigate方法？

如何解决与relativeTo一起使用时如何测试router.navigate方法？

测试 router.navigate 方法是否接受提供的 queryParams 并导航到正确的位置路径的正确方法是什么？

在组件文件中：--

syncQueryParams() {
    this.router.navigate([],{
      relativeto: this.activatedRoute,queryParams: {
        searchTerm: this.searchTerm,taskId: this.selectedResultId,version: this.selectedVersion,startDate: this.startDate
      },queryParamsHandling: 'merge'
    });
  }

测试床配置：--

beforeEach(async () => {
    await Testbed.configureTestingModule({
      declarations: [DataListingViewComponent],schemas: [NO_ERRORS_SCHEMA],providers: [{
        provide: DataListingViewFacade,useValue: {
          dispatch: jest.fn()
        }
      },DataListingViewFacade,provideMockStore({
        selectors: [],})],imports: [
        RouterTestingModule.withRoutes([]),AgGridModule,NgbModule
      ]
    })
      .compileComponents();
  });

测试 SyncQueryParmas:--

it(`syncQueryParams() should navigate to data-list page with query params`,() => {
              const version = component.selectedVersion;
              const startDate = component.startDate;
              const taskId = component.taskId;
              const searchTerm = component.searchTerm;
              spyOn(router,"navigate");
              component.syncQueryParams();
              expect(router.navigate).toHaveBeenCalledWith(['data-list'],{
                queryParams: { taskId: 1309,version: '133',startDate: '2021-01-11',searchTerm: 'hjgj' }
              });
            }
          );

此测试失败，因为它期望使用 navigate 方法的所有选项：--

DataListingViewComponent › syncQueryParams() should navigate with query params

    expect(spy).toHaveBeenCalledWith(...expected)

解决方法

也许您可以利用 args 中的 Jasmine 对象。

it(`syncQueryParams() should navigate to data-list page with query params`,() => {
              const version = component.selectedVersion;
              const startDate = component.startDate;
              const taskId = component.taskId;
              const searchTerm = component.searchTerm;
              const navigateSpy = spyOn(router,"navigate"); // get a handle on navigateSpy
              component.syncQueryParams();
              expect(navigateSpy.calls.mostRecent().args[0]).toEqual(['data-list']);
              expect(navigateSpy.calls.mostRecent().args[1]).toBeTruthy();
              // for the 2nd expect,you can get fancy with jasmine.objectContaining or 
              // other assertions
            }
          );
