如何编写已开通路由参数angular2的测试用例

import { ComponentFixture, TestBed } from '@angular/core/testing';
import { ActivatedRoute } from '@angular/router';
import { of } from 'rxjs';

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

const fakeActivatedRoute = {
  snapshot: {
    paramMap: {
      get: (param: string) => {
        if (param === 'yourParamName') {
          return 'yourParamValue';
        }
      }
    }
  }
};

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

  beforeEach(async () => {
    await TestBed.configureTestingModule({
      declarations: [YourComponent],
      providers: [
        { provide: ActivatedRoute, useValue: fakeActivatedRoute }
      ]
    }).compileComponents();
  });

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

  // 编写测试用例...
});

it('should retrieve and use the route parameter', () => {
  expect(component.yourParam).toBe('yourParamValue');
  // 根据路由参数执行相应的逻辑断言...
});
