我是测试新手，我试图弄清楚如何在每次测试后重置DOM，使每个测试用例都是独立的。在下面的代码中，我简单地复制了一个测试，第一个通过了，但第二个失败了，并显示消息：第一个月
因此，测试不会删除第一个示例。这是正常的行为吗？如何在测试之间重置？我尝试使用jest文档和react测试库文档中的cleanup方法，但这不起作用，根据文档，无论如何，它应该在每次测试后重置。

import { render } from '@testing-library/react';
import userEvent from '@testing-library/user-event';

import TaskList from './TaskList';

describe('TaskList Component', () => {
  it('Adds a new task when the add button is clicked', async () => {
    const user = userEvent.setup();
    const { getByPlaceholderText, getByAltText } = render(<TaskList />);

    const addButton = getByAltText('add');
    await user.click(addButton);

    expect(getByPlaceholderText('Title')).toBeInTheDocument();
  });

  it('Adds a new task when the add button is clicked', async () => {
    const user = userEvent.setup();
    const { getByPlaceholderText, getByAltText } = render(<TaskList />);

    const addButton = getByAltText('add');
    await user.click(addButton);

    expect(getByPlaceholderText('Title')).toBeInTheDocument();
  });
});

字符串
我使用了以下软件包：

"dependencies": {
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
  },
  "devDependencies": {
    "@testing-library/jest-dom": "^5.16.5",
