老师您好,按视频说的,我在src/setupTests.js里面添加了config代码

import { configure } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

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

但是测试会报错,说我需要配置(我明明配置了)

FAIL src/components/__test__/TotalPrice.test.js (8.764s)

  ● test TotalPrice component › component should render correct income&outcome number


          Enzyme Internal Error: Enzyme expects an adapter to be configured, but found none.
          To configure an adapter, you should call `Enzyme.configure({ adapter: new Adapter() })`
          before using any of Enzyme's top level APIs, where `Adapter` is the adapter
          corresponding to the library currently being tested. For example:

          import Adapter from 'enzyme-adapter-react-15';

官方文档说的也是模模糊糊,没说具体怎么配置
只有直接在测试组件内写配置才能运行
src/components/__test__/TotalPrice.js

import React from 'react'
import { shallow, configure } from 'enzyme'
import TotalPrice from '../TotalPrice'
import Adapter from 'enzyme-adapter-react-16'

configure({ adapter: new Adapter() })
const props = {
  income: 1000,
  outcome: 2000
}

describe('test TotalPrice component', () => {
  it('component should render correct income&outcome number', () => {
    const wrapper = shallow(<TotalPrice {...props} />)
    expect(wrapper.find('.income').text() * 1).toEqual(1000)
    expect(wrapper.find('.outcome').text() * 1).toEqual(2000)
  })
})
// 这样是可以正常运行的

但是明显这样写不是最佳选择,所以请问老师我哪里写错了?
