如何在React中测试所需的道具

我正在尝试用React和Jest编写简单的测试.

零件:

import React from "react";

class Task extends React.Component {

    render() {
        let onDelete = this.props.onDelete;
        return (
                

                    
 onDelete(this.props.taskId)}>delete{this.props.title}
                    
{this.props.description}
                
                );
    }
};

Task.propTypes = {
    title: React.PropTypes.string.isRequired,
    taskId: React.PropTypes.number.isRequired,
    onDelete: React.PropTypes.func.isRequired,
    description: React.PropTypes.string
};

Task.defaultProps = {
    description: ''
};

export default Task;

测试

import React from 'react';
import Task from '../src/components/Task';
import renderer from 'react-test-renderer';

test('Task should require properties', () => {
  const component = renderer.create( //this will give me React warnings which I would like to assert
    
  );
});

现在我想断言title,taskId并且onDelete是Task组件所必需的.我将得到React警告,不指定它们(或传递不同的类型).
