每次运行npm测试时都会收到此错误。
我想要做的只是使App.test.js工作。
我已经将所有依赖项更新为最新的（我无法做到的，除了“ axios”，“ react-bootstrap”，“ react-bootstrap-tpeahead”，“ bootstrap”，“ react-scripts”）。 / p>
我还被告知，从React v15及更高版本（我使用16.5.0）中，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';
对于每个单个组件和App.js，仍然无法正常工作。
我也有个建议：
“似乎是react-boostrap本身中的错误。请检查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在测试上下文中将不存在-毕竟这只是一个在节点中运行的控制台应用程序。”
我不知道这意味着什么，但是我确实对Transition.js有问题（如我得到的错误所示）
如何使此测试有效？我已经阅读了许多解决方案，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');
});

在测试环境中为ES6功能转换模块。只需将此代码添加到您的Jest配置中即可：
"transform": {
"\\.js$": "<rootDir>/node_modules/babel-jest"
},
