如何运行ui测试？

Question

当我开始测试应用程序时，我得到了一个错误：

    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:

..。

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

    Details:

    /home/mmvs/Desktop/ReactNative/node_modules/react-navigation/src/index.js:1
    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){export * from '@react-navigation/core';

如何解决这个错误？
