我嘗試測試我通過create-react-app. 只有一個自動生成的測試文件：import React from 'react';import ReactDOM from 'react-dom';import App from './App';it('renders without crashing', () => {  const div = document.createElement('div');  ReactDOM.render(<App />, div);  ReactDOM.unmountComponentAtNode(div);});這是我的package.json（我也有 package-lock.json（約 15k 行））：   {      "name": "project",      "version": "0.1.0",      "private": true,      "dependencies": {        "avro-js": "^1.9.1",        "axios": "^0.19.0",        "bootstrap": "^4.3.1",        "jquery": "^3.4.1",        "prop-types": "^15.7.2",        "react": "^16.10.2",        "react-dom": "^16.10.2",        "react-redux": "^7.1.1",        "react-scripts": "3.2.0",        "react-syntax-highlighter": "^11.0.2",        "reactstrap": "^8.0.1",        "redux": "^4.0.4",        "redux-thunk": "^2.3.0"      },      "scripts": {        "start": "react-scripts start",        "build": "react-scripts build",        "test": "react-scripts test",        "eject": "react-scripts eject"      },      "eslintConfig": {        "extends": "react-app"      },      "browserslist": {        "production": [          ">0.2%",          "not dead",          "not op_mini all"        ],        "development": [          "last 1 chrome version",          "last 1 firefox version",          "last 1 safari version"        ]      }    }當我嘗試使用測試腳本對其進行測試時，出現此錯誤：Jest 遇到意外令牌This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".細節：({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){export{ 默認為 a11yDark } 來自 './a11y-dark';另外，我沒有.babelrc文件。我試圖添加.babelrc但它沒有幫助（或者我做錯了）
