react-unit | Lightweight unit test library for ReactJS | Unit Testing library

Im trying to test my react app, created with (create-react-app) with cypress.

For some reason im getting this error:

As you can see it tries to get an element by ROOT_ID, ROOT_ID it's a const:

All i find to fix this it's an import on cypress/support/index.js

import "cypress-react-unit-test/support";

But as you can see here:

https://github.com/cypress-io/cypress-react-unit-test

This repo has been moved to the official cypress and i can't find the equivalent import.

Here is my plugins/index.js:

So i've been slamming my head against a wall for the last 5 hours or so trying to work out how to get this all working.

I've then replicated an internal project's structure and deps, and made it into a public repo in an effort to try and get some help. I know it's going to be some kind of bad configuration problem, but I just cant figure out where.

Could someone please help me understand what i need to do to get cypress react unit testing going within a webpack typescript react project?

When trying to run

I am trying to use cypress-react-unit-test to unit test my React components.

In this instance I have a Button, that gets passed a callback function to execute on click. I have the code below but fails immediately at the line highlighted. The error message is expected stub to have been called at least once, but it was never called.
