title: How to find nested element in jest by value of attribute
body: <p>I have a component with a Form and multiple Form.Field (sementic-ui-react) elements. 
  I want to find a Form.Field element by the text of the label inside the element.</p>
  
  <p><strong>AddItem.js</strong></p>
  
  <pre><code>class AddItems extends Component {
      ...
      render() {
        return (
          &lt;div&gt;
            &lt;h1&gt;Add Item&lt;/h1&gt;
            &lt;Form error onSubmit={this.handleSubmit.bind(this)}&gt;
              &lt;Form.Field&gt;
                &lt;label&gt;Type&lt;/label&gt;
              &lt;/Form.Field&gt;
              ...
  </code></pre>
  
  <p>Instead of just using .first(), .at(1) ... I'd like to find a Form.Field element based on the text in the label ('Type').</p>
  
  <p>Can this be done? If so, how?</p>
