Reactjs 使用ts jest调试typescript测试时.tsx React组件出错

我正在尝试使用ts jest在React应用程序中调试我的typescript测试

我的项目是用CreateReact应用程序生成的。 使用提供的测试：react scripts ts test-env=jsdom，我可以完美地运行我的类型脚本测试

但为了调试它们，我尝试在package.json中添加一个脚本条目，如下所示： 测试：debug:node-inspect brk./node_modules/jest/bin/jest.js-config=jest.config.debug.json

当我像：npm run test:debug这样运行时，我得到了预期的消息： 在ws://127.0.0.1:9229/bc733a7d-01d8-42eb-a18d-e59fe30a6393上侦听的调试器 但是，当我连接Chrome DevTools时，我单击run，然后，我的许多测试都会运行并通过，但是当运行可能是我在.test.tsx文件中进行的唯一测试时，我会出现这个错误

    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

我做错了什么？

有什么想法吗？

在Jest配置中，您需要存根一些Jest不理解的文件

模块映射：{ “\\.jpg | jpeg | png | gif | eot | otf | webp | svg | ttf | woff | woff2 | mp4 | webm | wav | mp3 | m4a | aac | oga$”： “/config/jest/mock/fileMock.js”， “\\.css”减去$：“identity obj proxy”， }

fileMock.js：

module.exports='测试文件存根'

它更具体地指向svg文件，而不是tsx。如果您在应用程序中使用Webpack loader处理SVG，则可能需要导入捆绑应用程序，而不是src。

{
  "preset": "ts-jest",
  "transformIgnorePatterns": ["node_modules/"]
