从create react app

Question

从create react应用程序弹出后无法运行测试。

第1步：弹出创建React应用

Step2：在package.json中，我们使用的是webpack 3.6，并做出反应：16.8.6

Step3：npm jest，npm酶，npm酶适配器-反应16，npm酶反应-intl和内部脚本：{test：jest}，

第4步：npm测试

“脚本”：{       “ test”：“开玩笑”   }，   “依赖关系”：{   “ jest”：“ ^ 24.8.0”，   “ enzyme”：“ ^ 3.10.0”，     “ enzyme-adapter-react-16”：“ ^ 1.14.0”，     “ enzyme-react-intl”：“ ^ 2.0.4”， }

带有intl测试用例的预期React组件应该通过 实际：  测试 /components/MapControls/SearchLocation.test.js   ●测试套件无法运行

Jest encountered an unexpected token

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".

Here's what you can do:
 • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
 • If you need a custom transformation specify a "transform" option in your config.
 • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

You'll find more details and examples of these config options in the docs:
https://jestjs.io/docs/en/configuration.html
