Jest TypeError: (0 , _jestUtil(...).tryRealpath) is not a function

🐛 Bug Report

I am trying to come up with correct jest config to test a simple screen:

// TestScreen.tsx
import React from 'react';
import { View, Text } from 'react-native';

export default function TestScreen() {
  return (
    <View data-test={'component-app'}>
      <Text>Test Screen</Text>
    </View>
  );
}

This is my test:

// App.test.js
import React from 'react';
import {shallow} from 'enzyme';
import TestScreen from '../src/screens/TestScreen';

/**
 * Return node(s) with the given data-test attribute.
 * @param {ShallowWrapper} wrapper - Enzyme shallow wrapper.
 * @param {string} val - Value of data-test attribute for search.
 * @returns {ShallowWrapper}
 */
export const findByTestAttr = (wrapper, val) => {
  return wrapper.find(`[data-test="${val}"]`);
};

/**
 * Factory function to create a ShallowWrapper for the App component
 * @function setup
 * @returns {ShallowWrapper}
 */
const setup = () => {
  return shallow(<TestScreen />);
};

test('renders without error', () => {
  const wrapper = setup();
  const component = findByTestAttr(wrapper, 'component-app');
  expect(component.length).toBe(1);
});

However, when running the test, I get this error:

yarn run v1.22.4
$ jest __tests__/App.test.js

This is my jest setup configuration

// jest.config.js
module.exports = {
  preset: 'react-native',
  collectCoverage: true,
  moduleDirectories: ['node_modules', 'src'],
  transform: {
    '^.+\\.js$': '<rootDir>/node_modules/react-native/jest/preprocessor.js',
  },
  setupFiles: ['<rootDir>setup-tests.js'],
  transformIgnorePatterns: ['node_modules/(?!(jest-)?react-native)'],
  coveragePathIgnorePatterns: ['/node_modules/', '/jest'],
  testEnvironment: 'jsdom',
};

// setup-tests.js
import Enzyme from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

Enzyme.configure({ adapter: new Adapter() });

Dear @SimenB Issue fixed by doing the following, it’s very strange, but it worked: Just delete the node_modules and run yarn install/npm install and the error is gone
