找到vue-test-utils中的第n个元素

import { mount } from '@vue/test-utils';
import MyComponent from '@/components/MyComponent.vue';

describe('MyComponent', () => {
  it('finds the nth element', () => {
    const wrapper = mount(MyComponent);
    
    // 假设我们要找的是第3个div元素
    const nthElement = wrapper.findAll('div').at(2); // 注意索引是从0开始的
    
    expect(nthElement.exists()).toBe(true);
  });
});

import { mount, nextTick } from '@vue/test-utils';

it('finds the nth element after DOM update', async () => {
  const wrapper = mount(MyComponent);
  
  // 等待DOM更新
  await nextTick();
  
  const nthElement = wrapper.findAll('div').at(2);
  expect(nthElement.exists()).toBe(true);
});
