React-native-apple-authentication: Jest mock or config suggestion?

[pacozaa]

Hey guys,

I appreciate your work!
I am currently configuring my project to work with Jest I know this might be beyond your problem but I came across this error when I run npm run test (I am using jest, of course) in my project.

I could probably use jest.mock but I prefer cleaner solution. Any suggestion?

FYI, below is the error I got.

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

    Details:

    import version from './version';
    ^^^^^^

    SyntaxError: Unexpected token import

I ignore it during jest transform like so

(base) mike@kunashir:~/work/Kullki/ksocialscore/packages/public-app (onboarding) % cat jest.config.js 
module.exports = {
  rootDir: './dist/tests/rnapp/js',
  roots: ['<rootDir>'],
  // transform: {
  //   '^.+\\.tsx?$': 'ts-jest',
  // },
  transformIgnorePatterns: [
    'node_modules/(?!@react-native-community/google-signin|react-native|reactxp-webview|react-pose-core|animated-pose|@react-native-community/async-storage|@invertase/react-native-apple-authentication)',
  ],
  moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx', 'json', 'node'],
  preset: 'react-native',
  testEnvironment: 'jsdom',
  collectCoverage: true,
  setupFilesAfterEnv: [
    './__mocks__/mockFirebase.js',
    './__mocks__/mockReactNative.js',
    './__mocks__/mockAsyncStorage.js',
  ],
};
// module.exports = {
//  testRegex: "(/__tests__/.*|(\\.|/)(test|spec))\\.(jsx?|tsx?)$",
// };

We'll accept PRs any time but this isn't actionable I don't think, would be user driven if there are changes as maintainers aren't having issues at the moment
