title: Error on jest when I try to run the test
body: <p>This is the error in the console: <code>Cannot find module 'expo' from 'setup.js'</code>. </p>
  
  <p>Below is my code: </p>
  
  <p><strong>component.test.js</strong>:</p>
  
  <pre><code>import React from 'react';
  import MyComponent from '../components/Component';
  import renderer from 'react-test-renderer';
  
  test('create component correctly', () =&gt;{
     const tree = renderer.create(
         &lt;MyComponent/&gt;
     ).toJSON();
     expect(tree).toMatchSnapshot();
  });
  </code></pre>
  
  <p><strong>Component.js</strong>:</p>
  
  <pre><code>import React, { Component } from 'react';
  import {Text, View } from 'react-native';
  
  export default class MyComponent extends React.Component{
     render(){
         return(
            &lt;View style={{flex: 1}}&gt;
                &lt;View style={styles.cameraContainer}&gt;
                    &lt;Text&gt; Test Component &lt;/Text&gt;
                &lt;/View&gt;
            &lt;/View&gt;
        );
     }
  }
  </code></pre>
  
  <p>When I try to use npm test the error that I mentioned before appears and I already try to uninstall and re-install jest and the error keeps showing.</p>
