我正在使用Jasmine创建我的单元测试,我对所涉及的分支有疑问.

有谁知道为什么代码部分显示分支未被覆盖,我们可以在下面看到？

这是单元测试:

describe('MyComponent', () => {
  let component: MyComponent;
  let fixture: ComponentFixture<MyComponent>;
  let myService: MyService;

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [ MyComponent ],
      imports: [ MaterializeModule, FormsModule, ReactiveFormsModule, HttpModule ],
      providers: [
        MyService,
        FormBuilder
      ]
    })
    .compileComponents();
  }));

  beforeEach(() => {
    fixture = TestBed.createComponent(MyComponent);
    component = fixture.componentInstance;
    slotsService = TestBed.get(MyService);
    fixture.detectChanges();
  });

  function updateForm(name, surname) {
    component.myForm.controls['name'].setValue(name);
    component.myForm.controls['surname'].setValue(name);
  }

  it('should create', () => {
    expect(component).toBeTruthy();
  });
}

有谁知道我该如何测试Router NavigationEnd Event？我在 Angular 2 中有下面的代码，我正在使用 Jasmine。

import { Injectable, EventEmitter } from '@angular/core';
import { Router, NavigationEnd, Event } from '@angular/router';

@Injectable()
export class IhmPageClassService {
    emitPageClass = new EventEmitter<string>();
    currentRoute: string;

    constructor(router: Router) {
        router.events.subscribe((event: Event) => {
            if (event instanceof NavigationEnd) {
                this.currentRoute = (<NavigationEnd>event).url;
            }
        });
    }
}

谢谢。

在我的app.component.ts中,我有下面的代码来获取路由名称,但我总是得到/.有谁知道为什么？我期望能获得例如home,contact.

import { Component } from '@angular/core';
import { Router } from '@angular/router';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {

  constructor(private router: Router) {
    console.log(router.url);
  }
}
