问题描述

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 。 / p>

根据我尝试的代码...

 让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,[]));
返回{
州:州,
已激活:已激活
}
}

但是来自@ angular / router / src / utils / tree的 import {TreeNode}; 似乎需要进行转换或者某事因为我得到...


解决方案

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},
{路径:'route2',组件:DummyComponent},
...
])
],
声明:[DummyComponent,RoutingComponent],
提供者:[
GuardClass,
{提供:RouterStateSnapshot,useValue:mockSnapshot}
]
})。compileComponents());

it( '不应该让用户因为某种原因克服防守',
inject([GuardClass],(guard:GuardClass)=> {
let fixture = TestBed.createComponent(RoutingComponent);
期待(guard.can激活(new ActivatedRouteSnapshot(),mockSnapshot))。toBe(false);
})
...


I have a simple router guard and I am trying to test the canActivate( route: ActivatedRouteSnapshot, state: RouterStateSnapshot ). I can create the ActivatedRouteSnapshot like this new ActivatedRouteSnapshot() but I cannot figure out how to create a mocked RouterStateSnapshot.

Per the code I tried...

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
    }
}

But import {TreeNode} from "@angular/router/src/utils/tree"; seems to need to be transpiled or something because I get...

解决方案

I managed to do it slightly differently but it should work for you :

...

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', component: DummyComponent},
        ...
      ])
  ],
  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);
  })
 ...
