如何使用路由器对Angular 2 RC4组件进行单元测试

npm install @angular/router@3.0.0 --save-dev

import { TestBed, async } from '@angular/core/testing';
import { RouterTestingModule } from '@angular/router/testing';
import { Component } from '@angular/core';
import { Router } from '@angular/router';

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

describe('TestComponent', () => {
  let router: Router;

  beforeEach(() => {
    TestBed.configureTestingModule({
      imports: [RouterTestingModule],
      declarations: [TestComponent]
    });

    router = TestBed.inject(Router);
  });

  it('should navigate to a specific route', async(() => {
    router.navigate(['/route']); // 替换成你要测试的路由路径

    router.events.subscribe(() => {
      expect(router.url).toBe('/route'); // 替换成你期望的路由路径
    });
  }));
});

ng test
