The following seems to work w/ JEST testing!

Here is the full package.json wrt Jest setup:

 "jest": {
    "setupEnvScriptFile": "./node_modules/react-native/jestSupport/env.js",
    "haste": {
      "defaultPlatform": "ios",
      "platforms": [
        "ios",
        "android"
      ],
      "providesModuleNodeModules": [
        "react-native"
      ]
    },
    "testPathIgnorePatterns": [
      "/node_modules/"
    ],
    "testFileExtensions": [
      "es6",
      "js"
    ],
    "moduleFileExtensions": [
      "js",
      "json",
      "es6",
      "ios.js"   <<<<<<<<<<<<<<<<<<<<<<<< this makes it work!
    ],
    "unmockedModulePathPatterns": [
      "react",
      "react-addons-test-utils",
      "react-native-router-flux",
      "promise",
      "source-map",
      "key-mirror",
      "immutable",
      "fetch",
      "redux",
      "redux-thunk",
      "fbjs"
    ],
    "collectCoverage": false,

  },

@bartonhammond I’ve opened a SO question about this http://stackoverflow.com/questions/36479136/test-platform-specific-extension-code-for-react-native

Have you managed to test platform-specific code under snowflake?
