mount with react native doesn't work

Using jest with enzyme and react native

I've followed the instructions in (did not add jsdom stuff in setup-tests.js as I'm using jest)
https://github.com/airbnb/enzyme/blob/master/docs/guides/react-native.md
And mount should work, according to the documentation. Please advise.

The stripped down test file as below.

/**
 * @jest-environment jsdom
 */
import React from 'react';
import { ScrollView } from 'react-native';
import { mount } from 'enzyme';

describe('Card', () => {
    let wrapper;
    describe('copy', () => {
        it('should render text', () => {
            const tree = mount(
                <ScrollView>
                </ScrollView>
            );
            expect(tree).toMatchSnapshot();
        });
    )};
)};

Current behavior

 Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: symbol.

    > 52 |             const tree = mount(
         |                                    ^
      53 |                 <ScrollView>
      54 |                 </ScrollView>
      55 |             );

Expected behavior

Should be able to mount react native component

Without an actual react-native adapter, it's not going to be reliable to use RN with enzyme. Follow #1436 for that.
