如何在TestBed配置中模拟路由器对象并注入到提供程序数组中

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

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

  class MockRouter {
    navigate = jasmine.createSpy('navigate');
    // 其他模拟的方法和属性...
  }

  beforeEach(() => {
    TestBed.configureTestingModule({
      imports: [
        RouterTestingModule
      ],
      providers: [
        { provide: Router, useClass: MockRouter }
        // 其他依赖的服务和提供者...
      ]
    });

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

  it('should navigate to a specific route', () => {
    // 测试代码中使用模拟的路由器对象进行导航操作...
    router.navigate(['/target-route']);

    // 验证导航方法是否被调用
    expect(router.navigate).toHaveBeenCalledWith(['/target-route']);
  });

  // 其他测试用例...
});
