This is one of the test that keeps failing:

it('snapshot testing', () => {
    const demoItem = mountWithIntl(<DemoItem store={testStore} demoUnchange={jest.fn()} demoReply={demoReply} demoRef={jest.fn()} />);
    expect(toJson(demoItem)).toMatchSnapshot();
  });

My package.json has this Jest configuration:

"jest": {
    "verbose": true,
    "snapshotSerializers": [
      "enzyme-to-json/serializer"
    ]
  }

"enzyme": "^3.9.0"
"enzyme-adapter-react-16": "^1.10.0"
"enzyme-react-intl": "^2.0.3"
"enzyme-redux": "^0.2.1"
"enzyme-to-json": "^3.3.5"
"babel-jest": "^24.1.0"

Could you put together a reproduction?

Yes, a minimal repo helps a lot in situation like this. Here is something I don’t see in the config:

To run the setup file to configure Enzyme and the Adapter with Jest … setupFilesAfterEnv

Guys, appreciate your help. We have decided to stick to babel 6 for now. We are reverting changes. I am closing this issue.
