angular – 如何为Router Guard Jasmine测试模拟RouterStateSnapshot

我有一个简单的路由器防护,我正在尝试测试canActivate(路由：ActivatedRouteSnapshot,状态：RouterStateSnapshot).我可以像这个新的ActivatedRouteSnapshot()一样创建ActivatedRouteSnapshot,但我无法弄清楚如何创建一个模拟的RouterStateSnapshot.

按照我试过的代码……

let createEmptyStateSnapshot = function(
    urlTree: UrlTree,rootComponent: Type<any>){
    const emptyParams = {};
    const emptyData = {};
    const emptyQueryParams = {};
    const fragment = '';
    const activated = new ActivatedRouteSnapshot();
    const state = new RouterStateSnapshot(new TreeNode<ActivatedRouteSnapshot>(activated,[]));
    return {
        state: state,activated: activated
    }
}

但从“@ angular / router / src / utils / tree”导入{TreeNode};似乎需要进行转换或其他因为我得到……

Uncaught SyntaxError: Unexpected token export
at webpack:///~/@angular/router/src/utils/tree.js:8:0 <- test.bundle.ts:72431

我设法做的略有不同,但它应该适合你：

...

let mockSnapshot:any = jasmine.createSpyObj<RouterStateSnapshot>("RouterStateSnapshot",['toString']);

@Component({
  template: '<router-outlet></router-outlet>'
})
class RoutingComponent { }

@Component({
  template: ''
})
class DummyComponent { }

describe('Testing guard',() => {
  beforeEach(() => TestBed.configureTestingModule({
    imports: [
      RouterTestingModule.withRoutes([
        {path: 'route1',component: DummyComponent},{path: 'route2',...
      ])
  ],declarations: [DummyComponent,RoutingComponent],providers: [
    GuardClass,{provide: RouterStateSnapshot,useValue: mockSnapshot}
  ]
}).compileComponents());

  it('should not allow user to overcome the guard for whatever reasons',inject([GuardClass],(guard:GuardClass) => {
      let fixture = TestBed.createComponent(RoutingComponent);
      expect(guard.canActivate(new ActivatedRouteSnapshot(),mockSnapshot)).toBe(false);
  })
 ...
