rasa-nlu-editor/src/components/App.test.js

This is a tool to edit your training examples for [rasa NLU](https://github.com/RasaHQ/rasa-nlu-editor) But the original project was not maintained, so I create a new repo.

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';

it('renders without crashing', () => {
  const div = document.createElement('div');
  ReactDOM.render(<App />, div);
});
