title: Jest - react-native SyntaxError: Unexpected token import
body: <p>I am running jest test in react native and it fails giving "SyntaxError: Unexpected token import"</p>
  
  <p>Here is my trimmer import code: - </p>
  
  <pre><code>import React, { Component } from 'react';
  import { Container,
    Content,
    Text,
    Button,
    Icon,
    Footer,
    FooterTab,
    Item,
    Input,
    View,
    Picker
  } from 'native-base';
  
  import { bindActionCreators } from 'redux';
  import { connect } from 'react-redux';
  </code></pre>
  
  <p>Here is error: </p>
  
  <p>FAIL  <strong>tests</strong>/home-page-test.js
    ● Test suite failed to run</p>
  
  <pre><code>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://facebook.github.io/jest/docs/en/configuration.html

  <p>Not sure what I am doing wrong in import. Any tips are most welcomed.</p>
