Question

我相信这是一个设置错误，但是我不知道该怎么办了，我尝试了很多东西。我们有一个应用程序设置，测试失败并显示错误：

src/__tests__/App.spec.tsx
  ● Test suite failed to run

    SyntaxError: .../react-native/Libraries/Storage/AsyncStorage.js: Unexpected token, expected "," (31:19)

      29 |  */

         |                    ^

这是App.spec.tsx代码：

import React from 'react';
import renderer from 'react-test-renderer';

import { App } from '../app';

it('renders correctly with defaults', () => {
  const app = renderer.create(<App />).toJSON();
  expect(app).toMatchSnapshot();
});

我的jest.json：

{
  "preset": "react-native",
  "cacheDirectory": ".jest/cache",
  "testRegex": "(/__tests__/.*|\\.(test|spec))\\.(ts|tsx|js)$",
  "moduleFileExtensions": [
    "ts",
    "tsx",
    "js"
  ],
  "transform": {
    "^.+\\.(js)$": "<rootDir>/node_modules/babel-jest",
    "\\.(ts|tsx)$": "<rootDir>/node_modules/ts-jest/preprocessor.js"
  },
  "transformIgnorePatterns": [
    "node_modules/(?!(jest-)?react-native|react-navigation)"
  ],
  "testPathIgnorePatterns": [
    "\\.snap$",
    "<rootDir>/node_modules/",
    "<rootDir>/lib/",
    "./build"
  ],
  "globals": {
    "window": true
  }
}

我可以提供任何有用的信息吗？这是流类型的问题，巴别尔...？我的.babelrc非常简单。
