当我尝试模拟我的 React 组件时，我遇到了错误。

? 测试套件无法运行

C:\UBS\Dev\workspace\topcat-ui\node_modules\antd\lib\style\index.css:9
html {
     ^
SyntaxError: Unexpected token {

  at ScriptTransformer._transformAndBuildScript (node_modules/jest-runtime/build/ScriptTransformer.js:289:17)
  at Object.<anonymous> (node_modules/antd/lib/pagination/style/css.js:3:1)
  at Object.<anonymous> (src/main/webapp/js/pages/dashboard/Dashboard.jsx:1:176)

这就是我的 package.json 的样子。有人可以指出我正确的方向吗？

    "redux": "^3.6.0",

}

这就是我的测试用例的样子

import React from 'react';
import {mount} from 'enzyme';
import Dashboard from '../../../main/webapp/js/pages/dashboard/Dashboard';

function setup() {
    const Dashboard = mount(<Dashboard />);
    return {
        Dashboard
    }
}

describe('Components', () => {
    describe('Dashboard', () => {
        it('should render itself', () => {
            const { Dashboard } = setup();
            expect(Dashboard.find('table').length).toBe(1);
        });
    });
});

我假设你正在使用 webpack？从文档中查看此注释。您可以在您的 jest 配置中使用moduleNameMapper或选项来模拟/忽略您的 css 文件。transform

{
 "jest": {
    "moduleNameMapper": {
      "\\.(css|less)$": "identity-obj-proxy"
    },
    "transform": {
      "\\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$": "<rootDir>/fileTransformer.js"
    }
  }
}


// fileTransformer.js
const path = require('path');

module.exports = {
  process(src, filename, config, options) {
    return 'module.exports = ' + JSON.stringify(path.basename(filename)) + ';';
  },
};

加载样式表可能有些失败。您必须提供有关组件和模拟过程的更多信息。它可能将 .css 文件加载为 .js 文件。
