意外的导入令牌-使用Jest测试React Native [英] Unexpected import token - testing React Native with Jest

问题描述

当我尝试用玩笑来测试我的react-native应用程序时，我收到一个奇怪的导入错误.我已经安装了babel-jest，babel-preset-react-native，jest，jest-react-native和react-test-render，但在运行npm test时收到此错误消息.

I'm getting a weird import error when I try to test my react-native app with jest. I have babel-jest, babel-preset-react-native, jest, jest-react-native and react-test-render all installed but get this error message when I run npm test.

●测试套件无法运行

测试套件:1个失败，1个通过，总共2个 测试:1次通过，共1次 快照:1次通过，共1次 时间:1.011秒

推荐答案

弄清楚了，基本上将所有使用es6语法的节点模块都放在了transformIgnorePatterns中.

Figured it out, basically throw any node modules that use es6 syntax in transformIgnorePatterns.

"transformIgnorePatterns":[ "node_modules/(?! react-native | native-base | reclone-clone-referenced-element)" ]

"transformIgnorePatterns": [ "node_modules/(?!react-native|native-base|react-clone-referenced-element)" ],
