javascript - Cypress React，找不到安装组件的根元素

Question

我试图测试我的 react 应用程序，用柏树创建(create-react-app)。
出于某种原因，我收到此错误:

如您所见，它试图通过 ROOT_ID 获取元素，ROOT_ID 它是一个常量:

我找到解决这个问题的所有方法都是 cypress/support/index.js 上的导入

import "cypress-react-unit-test/support";

但正如你在这里看到的:
https://github.com/cypress-io/cypress-react-unit-test
这个 repo 已移至官方柏树，我找不到等效的导入。
这是我的插件/index.js:

const findWebpack = require('find-webpack')
const webpackPreprocessor = require('@cypress/webpack-preprocessor')

/**
 * @type {Cypress.PluginConfig}
 */
module.exports = (on) => {
  // find the Webpack config used by react-scripts
  const webpackOptions = findWebpack.getWebpackOptions()

  if (!webpackOptions) {
    throw new Error('Could not find Webpack in this project 😢')
  }

  const cleanOptions = {
    reactScripts: true,
  }

  findWebpack.cleanForCypress(cleanOptions, webpackOptions)

  const options = {
    webpackOptions,
    watchOptions: {},
  }

  on('file:preprocessor', webpackPreprocessor(options))
}

所以显然我使用了错误的柏树模块。
这是用于 react 测试

npx cypress open-ct

或者

npx cypress run-ct

Cypress /插件/index.js:

const injectDevServer = require("@cypress/react/plugins/react-scripts")

module.exports = (on, config) => {
  injectDevServer(on, config)
  return config
}
