Does not work with enzyme

[BenLorantfy]

The following code produces a weird snapshot value.

Code:

import React from 'react';
import styled from 'styled-components';
import { shallow } from "enzyme";
import toJson from 'enzyme-to-json'

it('renders without crashing', () => {
  const Button = styled.div`
    color: red;
  `;

  const wrapper = shallow(<Button />);
  expect(toJson(wrapper)).toMatchSnapshot();
});

Snapshot:

// Jest Snapshot v1, https://goo.gl/fbAQLP

exports[`renders without crashing 1`] = `
<StyledComponent
  forwardedComponent={
    Object {
      "$$typeof": Symbol(react.forward_ref),
      "attrs": Array [],
      "componentStyle": ComponentStyle {
        "componentId": "sc-bdVaJa",
        "isStatic": false,
        "rules": Array [
          "
    color: red;
  ",
        ],
      },
      "displayName": "styled.div",
      "foldedComponentIds": Array [],
      "render": [Function],
      "styledComponentId": "sc-bdVaJa",
      "target": "div",
      "toString": [Function],
      "usesTheme": false,
      "warnTooManyClasses": [Function],
      "withComponent": [Function],
    }
  }
  forwardedRef={null}
/>
`;

Expected: (I get this if I try react-test-renderer directly instead of enzyme)

// Jest Snapshot v1, https://goo.gl/fbAQLP

exports[`renders without crashing 1`] = `
.c0 {
  color: red;
}

<div
  className="c0"
/>
`;

Versions:

    "enzyme": "^3.10.0",
    "enzyme-adapter-react-16": "^1.14.0",
    "enzyme-to-json": "^3.4.0",
    "jest-styled-components": "^6.3.3",
    "react": "^16.10.1",
    "react-dom": "^16.10.1",
    "react-scripts": "3.1.2",
    "styled-components": "^4.4.0"

Tried in a brand new project using create-react-app.

Debugging notes:

• Works with styled-components version 3.4.10
• Breaks in styled-components version 4.0.0
• Seems like enzyme tests are disabled? 🤔 https://github.com/styled-components/jest-styled-components/blob/v4/test/styleSheetSerializer.spec.js#L186
• Cloned and added simple test case for enzyme shallow without using theme. Test produces similar snapshot as above.

Any update on this, getting same issue.

Also this seems to be specific to shallow render as enzyme's render method works and import ShallowRenderer from 'react-test-renderer/shallow'; result in the same issue as enzyme's shallow

@probablyup I think this should probably be higher priority, no?

so, I have been trying to get this working all day long .. just upgrade jest-styled-components to v7, then you will get an error, after searching around you also need styled-components v5 and everything is back to working 🤷‍♂️

hope it helps someone else
