酶-如何从容器中获取函数的实例，作为道具传递给组件？

import { mount, configure } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16'; // 或者适用于React 15的适配器

configure({ adapter: new Adapter() });

import React from 'react';

class ContainerComponent extends React.Component {
  myFunction() {
    // 函数实例
  }

  render() {
    return <ChildComponent myFunction={this.myFunction} />;
  }
}

import React from 'react';

class ChildComponent extends React.Component {
  render() {
    const { myFunction } = this.props;
    // 使用函数实例
    return <div>{myFunction()}</div>;
  }
}

import { mount } from 'enzyme';

describe('ContainerComponent', () => {
  it('should pass function instance to ChildComponent', () => {
    const wrapper = mount(<ContainerComponent />);
    const childComponent = wrapper.find('ChildComponent');
    const myFunction = childComponent.props().myFunction;
    // 断言函数实例是否正确传递给了ChildComponent
    expect(typeof myFunction).toBe('function');
  });
});
