SyntaxError：意外的令牌

标签： javascript reactjs testing jestjs

我正在尝试配置我的应用程序（https://github.com/freeCodeCamp/meeting-for-good）进行测试。我正在使用开玩笑。但是，当我运行测试时出现错误。看起来我的AboutDialog组件的路径无法转换。 

   zach@zach-VirtualBox:~/Documents/Code/fcc-for-good/meeting-for-good$ npm run test

我正在尝试将AboutDialog组件导入我的测试。

import React from 'react';
import Dialog from 'material-ui/Dialog';
import FlatButton from 'material-ui/FlatButton';
import cssModules from 'react-css-modules';

import PropTypes from 'prop-types';
import styles from './about-dialog.css';

const inlineStyles = {
  modal: { content: { width: '630px', maxWidth: '630px' }, bodyStyle: { paddingTop: 10, fontSize: '25px' } },
};

const AboutDialog = (props) => {
  const { cbOpenModal, openModal } = props;
  const actions = [
    <FlatButton label="close" primary onTouchTap={() => cbOpenModal()} />,
  ];
  return (
    <Dialog
      contentStyle={inlineStyles.modal.content}
      bodyStyle={inlineStyles.modal.bodyStyle}
      actions={actions}
      modal
      styleName="AboutDialog"
      open={openModal}
    >
      <h1 styleName="titleStyle">Meeting for Good</h1>
      <h6 styleName="versionStyle">Version {process.env.versionNumber}</h6>
      <h4 styleName="descStyle">THE BEST MEETING COORDINATION APP</h4>
      <h6>Created by campers from <a href="https://www.freecodecamp.com">FreeCodeCamp</a></h6>
      <h6><a href="https://github.com/freeCodeCamp/meeting-for-good/"> License and GitHub Repository</a></h6>
    </Dialog>
  );
};

AboutDialog.propTypes = {
  cbOpenModal: PropTypes.func.isRequired,
  openModal: PropTypes.bool.isRequired,
};

export default cssModules(AboutDialog, styles);

我的测试。如果我从测试中删除AboutDialog导入，则运行测试套件。

    import React from 'react';
    import AboutDialog from '../client/components/AboutDialog/AboutDialog';
    import { shallow } from 'enzyme';

    describe('Test', () => {
        it('should test', () => {  

      });

});

我的.babelrc文件。

答案 0 :(得分：1)

我明白了。我只需要使用jest-css-modules（https://www.npmjs.com/package/jest-css-modules）。

所以我只需要添加make package.json 

"jest": {
    "transform": {
      ".*": "<rootDir>/node_modules/jest-css-modules"
    }
  }
