title: I cannot import components in React
body: <p>Hi guys this is my App file:</p>
  
  <pre><code>import React, { Component } from 'react';
  import test2 from './test2';
  import './App.css';
  
  class App extends Component {
    render() {
      return &lt;test2 /&gt;;
    }
  }
  export default App;
  </code></pre>
  
  <p>and this is my test2 component :</p>
  
  <pre><code>import React, { Component } from 'react';
  
  class test2 extends Component {
    render() {
      return &lt;div&gt;hello&lt;/div&gt;;
    }
  }
  export default test2;
  </code></pre>
  
  <p>but for some reason I cannot see it in my app component,
  does anyone see the error? 
  this is what I get:
  'test2' is declared but its value is never read. [6133]</p>
