I'm trying to write my first ever test for my code, and I am having trouble just getting the very basics to work. Here's what I have:



//namePlate.js

import React from 'react';



const NamePlate = (props)=>(

  <div className = 'namePlate' style = {props.color(props.name)}>

    {props.name}

    <button id = {props.id} type = 'button' onClick = {props.onClick}>x</button>}

  </div>

)



export default NamePlate



//namePlate.test.js



import React from 'react';

import NamePlate from './namePlate.js';

import {shallow} from 'enzyme';





it('renders', () => {

  const wrapper = shallow(<NamePlate name = 'Test' id = '1' onClick ={() =>{}} color = {()=>{}}/>);

  expect(wrapper.find('div')).to.have.lengthOf(1);



})


I am getting "TypeError: Cannot read property 'have' of undefined," and I am really unsure of what I am doing wrong. Any help is appreciated.
