如何在angular (jasmine)中路由中模拟参数

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

beforeEach(() => {
  TestBed.configureTestingModule({
    imports: [RouterTestingModule],
    providers: [
      {
        provide: ActivatedRoute,
        useValue: {
          snapshot: {
            paramMap: convertToParamMap({ id: '123' }) // 模拟参数
          }
        }
      }
    ]
  });
});

it('should get route params', () => {
  const route = TestBed.inject(ActivatedRoute);
  expect(route.snapshot.paramMap.get('id')).toBe('123');
});
