我如何将一个值传递给一个没有道具的组件来测试它呢？

// 父组件
import React from 'react';
import ChildComponent from './ChildComponent';

class ParentComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      value: 'Hello World',
    };
  }

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

export default ParentComponent;

// 子组件
import React from 'react';

class ChildComponent extends React.Component {
  render() {
    return <div>{this.props.value}</div>;
  }
}

export default ChildComponent;

// 测试
import React from 'react';
import { mount } from 'enzyme';
import ParentComponent from './ParentComponent';

describe('ParentComponent', () => {
  it('should pass the value to the ChildComponent', () => {
    const wrapper = mount(<ParentComponent />);
    const childComponent = wrapper.find('ChildComponent');
    expect(childComponent.prop('value')).toEqual('Hello World');
  });
});
