如何模拟角度路由中的参数（茉莉花）

Question

如何模拟参数

this.id = params['id'];

（路由器角度）在茉莉花测试中？

我的代码：

constructor(public activatedRoute: ActivatedRoute, private store: Store) { }
          
ngOnInit(): void {
  this.store.dispatch(new LoadCategoriesAction());
  this.store.dispatch(new LoadProductsByMainAction(false));
  this.sub = this.activatedRoute.params.subscribe(params => {
    this.id = params['id'];
    console.log("!!!!!!!!!!!!!");
    console.log(this.id);
    if (this.id) {
      this.store.dispatch(new LoadProductByIdAction(this.id));
    }
  })
}

您必须为 ActivatedRoute 创建一个模拟，如下所示；

providers: [
...,
{provide: ActivatedRoute, useValue: {params: of({id: '123'})}}
]
