title: NativeBase Content not rendered in Jest with react-native-testing-library
body: <p>I have some <strong>react-native/expo</strong> with <strong>native-base</strong> code that runs normally on the phone or emulator.
  I tried creating a test for it using <strong>jest</strong> and <strong>react-native-testing-library</strong>. When doing so, whatever is inside the <strong></strong> from <strong>native-base</strong> is not rendered and cannot be found in the test.</p>
  
  <p><strong>Has anyone been through this and would know a solution so the children of Content are rendered during testing?</strong></p>
  
  <p>An example code is below to illustrate what I am saying.
  Thank you very much for the help.</p>
  
  <pre class="lang-py prettyprint-override"><code>import { render } from 'react-native-testing-library';
  import {
    Content, Container, Text
  } from 'native-base';
  
  
  class App extends React.Component {
  
    render() {
      return (
        &lt;Container&gt;
          &lt;Content&gt;
            &lt;Text testID="textId"&gt;Hello&lt;/Text&gt;
          &lt;/Content&gt;
        &lt;/Container&gt;
      );
    }
  }
  
  describe('Testing Content', () =&gt; {
    const { queryByTestId } = render(&lt;App /&gt;)
    it('renders text inside content', () =&gt; {
      expect(queryByTestId('textId')).not.toBeNull()
    });
  
  })
