Unable to run the tests in ESM

[vasyas]

What is your Scenario?

Unable to run the simplest tests when adding type: "module" to package.json

What is the Current behavior?

After launching testcafe I'm getting the error:

~/projects/github/testcafe-esm-bug> testcafe chrome test.mjs --esm
ERROR Cannot prepare tests due to the following error:

ReferenceError: require is not defined in ES module scope, you can use import instead
    at file:///Users/vasyas/projects/github/testcafe-esm-bug/test.mjs:1:27

Type "testcafe -h" for help.

What is the Expected behavior?

The test should be launched

What is the public URL of the test page? (attach your complete example)

http://example.com

What is your TestCafe test code?

import { Selector } from 'testcafe';

fixture `Fixture`
    .page('http://example.com');

test('test', async t => {
  await t
      .click('body')
      .expect(Selector('h1').text).eql('Example Domain');
});
