每次运行 npm test 时都会出现此错误。

我想要的只是让 App.test.js 工作。

我已将所有依赖项更新为最新版本（除了“axios”、“react-bootstrap”、“react-bootstrap-typeahead”、“bootstrap”、“react-scripts”，我无法更新）。

我还被告知，从 React v15 及更高版本（我使用 16.5.0）开始，我必须从“prop-types”而不是“React”导入 PropTypes。但是，我添加了这一行

import PropTypes from 'prop-types';

对于每个组件和 App.js，仍然不起作用。

我还得到了一个建议：

“似乎是react-boostrap本身的错误。检查 Transition.js 中出现错误的行。我敢打赌它会尝试访问 window 上的属性。但是 window 不会存在于测试上下文中 - 它只是毕竟是在节点中运行的控制台应用程序”。

我不知道这意味着什么，但我确实有 Transition.js 的问题（如我收到的错误所示）

我怎样才能让这个测试发挥作用？我读过很多解决方案，但没有帮助我......

测试代码：

import React from 'react';
import PropTypes from 'prop-types'; 
import {shallow} from 'enzyme';
import CheckboxWithLabel from '../CheckboxWithLabel';
test('CheckboxWithLabel changes the text after click', () => {
  const checkbox = shallow(
    <CheckboxWithLabel labelOn="On" labelOff="Off" />
  );
  expect(checkbox.text()).toEqual('Off');
  checkbox.find('input').simulate('change');
  expect(checkbox.text()).toEqual('On');
});

在测试环境中将模块转换为 ES6 功能。只需将此代码添加到您的 Jest 配置中：

 "transform": {
  "\\.js$": "<rootDir>/node_modules/babel-jest"
},
