如何测试从角度组件字符串数组渲染的[routerLink]值？

import { ComponentFixture, TestBed } from '@angular/core/testing';
import { RouterTestingModule } from '@angular/router/testing';
import { By } from '@angular/platform-browser';

import { YourComponent } from './your.component';

describe('YourComponent', () => {
  let component: YourComponent;
  let fixture: ComponentFixture<YourComponent>;

  beforeEach(async () => {
    await TestBed.configureTestingModule({
      imports: [RouterTestingModule],
      declarations: [YourComponent]
    })
    .compileComponents();
  });

  beforeEach(() => {
    fixture = TestBed.createComponent(YourComponent);
    component = fixture.componentInstance;
  });

  it('should render [routerLink] values correctly', () => {
    // 设置要测试的[routerLink]值
    component.routerLinks = ['link1', 'link2'];

    // 触发变更检测
    fixture.detectChanges();

    // 获取渲染的[routerLink]元素
    const routerLinkElements = fixture.debugElement.queryAll(By.css('[routerLink]'));

    // 检查渲染的[routerLink]值是否与预期相符
    expect(routerLinkElements.length).toBe(2);
    expect(routerLinkElements[0].nativeElement.getAttribute('routerLink')).toBe('link1');
    expect(routerLinkElements[1].nativeElement.getAttribute('routerLink')).toBe('link2');
  });
});
