Jest bug with expo when using another dependency such as @shoutem

[archywillhe]

Version:

 "expo": {
    "sdkVersion": "25.0.0"
  }

Jest Test always failed with syntax error

  /Users/a/ArchyBox/lateJan/Archy/node_modules/@expo/vector-icons/fonts/MaterialIcons.ttf:1
    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){


SyntaxError: Invalid or unexpected token

      at ScriptTransformer._transformAndBuildScript (node_modules/jest-runtime/build/script_transformer.js:318:17)
      at Object.<anonymous> (node_modules/@expo/vector-icons/MaterialIcons.js:4:64)
      at Object.<anonymous> (node_modules/@shoutem/ui/components/ImagePreview.js:10:20)

Current config for jest ("jest-expo": "25.0.0")

  "jest": {
    "preset": "jest-expo",
    "transformIgnorePatterns": [
          "node_modules/(?!react-native|expo|@expo|react-navigation|native-base-shoutem-theme|@shoutem/theme|@shoutem/animation|@shoutem/ui|tcomb-form-native)"
    ]
  },

Runs fine without third party dependency @shotem. Error only arises when added @shotem and "transformIgnorePatterns".

Merging this into another issue for what appears to be the same bug: #1317

try out jest-expo@25.1.0-beta.0 and let me know if it resolves your problem
