单元测试 – 如何在React中测试所需的道具

零件：

import React from "react";

class Task extends React.Component {

    render() {
        let onDelete = this.props.onDelete;
        return (
                <li>
                    <div className="collapsible-header"><i className="material-icons" onClick={() => onDelete(this.props.taskId)}>delete</i>{this.props.title}</div>
                    <div className="collapsible-body"><p>{this.props.description}</p></div>
                </li>
                );
    }
};

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
    <Task></Task>
  );
});

现在我想断言任务组件需要title,taskId和onDelete.我将得到React警告,不指定它们(或传递不同的类型).
