1) Run the test `ava ava-snapshot-split-error.js`. 2) Change 'change me' to something else. 3) Re-run the test to throw the error `TypeError: Cannot read property 'split' of null`.

ava-snapshot-split-error.js

import React from 'react';
import test from 'ava';
import { render } from 'enzyme';

const TestMe = ({ me }) => (
  <div>
    <p>{me}</p>
  </div>
);

test('renders the component', t => {
  const wrapper = render(<TestMe me='change me' />);
  t.snapshot(wrapper.html());
});
