如何在无状态组件中执行函数，以便在Jest和Jest中进行测试

// MyComponent.js

import React from 'react';

const MyComponent = ({ onClick }) => {
  const handleClick = () => {
    onClick('Hello, World!');
  };

  return (
    <button onClick={handleClick}>Click me</button>
  );
};

export default MyComponent;

// MyComponent.test.js

import React from 'react';
import { shallow } from 'enzyme';
import MyComponent from './MyComponent';

describe('MyComponent', () => {
  it('should call onClick function with correct argument', () => {
    const onClickMock = jest.fn();
    const wrapper = shallow(<MyComponent onClick={onClickMock} />);
    const button = wrapper.find('button');

    button.simulate('click');

    expect(onClickMock).toHaveBeenCalledWith('Hello, World!');
  });
});
