Component tests not running after trying to installGlobals()

[powerfulech0]

New to Remix, was wondering what I am doing wrong in this approach:

I have a test for a component that uses the fetcher in it:

test('loads Program Selector', async () => {
  function TestProgramSelector() {
    return (
      <ProgramSelector
        programs={testPrograms}
        activePrograms={activeTestPrograms}
      />
    );
  }

  const RemixStub = createRemixStub([
    {
      path: '/',
      Component: TestProgramSelector,
      loader() {
        return null;
      },
    },
  ]);

  render(<RemixStub />);

  await waitFor(() => screen.findByText('Program Selector'));
});

When I run the tests it gives this error back:

Which led me to trying to install the polyfills with installGlobals in a Jest setup file:

import { installGlobals } from '@remix-run/node';

beforeAll(() => {
  installGlobals();
});

After which I get this error message:

Any ideas what I'm missing here?

Do you have a sample repo?

Here's how I setup Vitest in my template.

https://github.com/kiliman/remix-vite-template/blob/main/docs/setup/vitest.md
https://github.com/kiliman/remix-vite-template/tree/main/tests/setup

And here's a sample test:

import { createRemixStub } from '@remix-run/testing'
import { render, screen } from '@testing-library/react'
import userEvent from '@testing-library/user-event'
import { expect, test } from 'vitest'
import Counter, { action, loader } from './counter'

test('counter increments when clicked', async () => {
  const App = createRemixStub([
    {
      path: '/counter',
      Component: Counter,
      loader,
      action,
    },
  ])
  await render(<App initialEntries={['/counter']} />)
  const button = await screen.findByRole('button', { name: /count:/i })
  expect(button).toHaveTextContent('Count: 0')
  await userEvent.click(button)
  expect(button).toHaveTextContent('Count: 1')
})

I created one @kiliman https://github.com/lukasalvarezdev/jest-remix-repro

It happens with jest but not with vitest. Thanks for the help!
