tl;dr

For a component like

import React, { Component } from 'react';

import styles from './App.css';

export default class App extends Component {
  render() {
    return (
      <div className={styles.root}>
        <h1 className={styles.hello}>Hello, world!</h1>
      </div>
    );
  }
}

it generates a snapshot as below:

exports[`test App renders correctly 1`] = `
<div
  className="root">
  <h1
    className="hello">
    Hello, world!
  </h1>
</div>
`;
