How to use Jest with opencCV.js?

I'm using jest and enzyme to write tests for my React application. In my App component opencv.js is imported. And the test fails. This is a simplified version of my component

import '../lib/opencv/opencv';

function App () {
  console.log('App');
  return 2;
}

export { App };

And here is the test

import { App } from './App';

describe('App',() => {
  test('App with opencv.js', () => {
   expect(App().toBe(2));
  });
});

this test fails with the following error

 FAIL  src/App.test.jsx
 ● Test suite failed to run

ReferenceError: Module is not defined

  28 | 
  29 |   if (typeof Module === 'undefined')
> 30 |     Module = {};
     |           ^
  31 |   return cv(Module);
  32 | }));

  at Object.<anonymous> (lib/opencv/opencv.js:2:2)
  at Object.<anonymous> (src/App.jsx:1:1)
  at Object.<anonymous> (src/App.test.jsx:1:1)

if I comment this line

import '../lib/opencv/opencv';

the test will pass.

How should I write tests for the component where I import OpenCV?
