如何在react jest单元测试中模拟"<script>“

// 假设要测试的组件是一个使用了<script>标签的组件
import React from 'react';

class MyComponent extends React.Component {
  componentDidMount() {
    const script = document.createElement('script');
    script.src = 'https://example.com/script.js';
    document.head.appendChild(script);
  }

  render() {
    return <div>Hello World</div>;
  }
}

export default MyComponent;

import React from 'react';
import { render } from '@testing-library/react';
import MyComponent from './MyComponent';

describe('MyComponent', () => {
  it('should render without errors', () => {
    const createElementSpy = jest.spyOn(document, 'createElement');
    const appendChildSpy = jest.spyOn(document.head, 'appendChild');

    render(<MyComponent />);

    expect(createElementSpy).toHaveBeenCalledWith('script');
    expect(appendChildSpy).toHaveBeenCalled();

    createElementSpy.mockRestore();
    appendChildSpy.mockRestore();
  });
});
