TypeError: Cannot call a class as a function

Bug

What is the current behavior?

My code is running fine in production but tests are not passing when importing an object from a file, error is: TypeError: Cannot call a class as a function at at _classCallCheck (node_modules/react-native/jest/mockComponent.js:9:616)

Object I'm importing:

export const Fabric = {
  Crashlytics: {
    logException: jest.fn(),
    setString: jest.fn(),
    setUserEmail: jest.fn(),
    recordError: jest.fn()
  },
  Answers: {
    logSignUp: jest.fn(),
    logException: jest.fn(),
    logCustom: jest.fn(),
    logLogin: jest.fn()
  },
};

import statement

const {Answers} = require('../../../test/setup').Fabric;

Commenting that line ^ makes the test pass

Just adding that import statement throws Cannot call a class as a function at at _classCallCheck (node_modules/react-native/jest/mockComponent.js:9:616)

The same import statement works fine in other files, this error happens running jest -u --runInBand, doesn't happen when running the code in production.

The actual test:

const tree = renderer.create(
      <MyComponent />
    ).toJSON();
expect(tree).toMatchSnapshot();

What is the expected behavior?

Test should pass or tell me what the real problem is.

Please provide your exact Jest configuration and mention your Jest, node, yarn/npm version and operating system.
