Is this a regression?

No

Description

Hi,

The Angular team has already announced some time ago their transition to Jest here. We can already play with an experimental version.

I have noticed that it does not work with Spectator which may become an issue.

Please provide a link to a minimal reproduction of the bug

https://github.com/Tommy228/spectator-angular-builders-jest

Please provide the exception or error you saw

dist/test-out/ca3e369e-b853-4b8a-a768-4d0075c3d656/app.component.spec.mjs
  ● Test suite failed to run

    Do not import `@jest/globals` outside of the Jest test environment

      at node_modules/@jest/globals/build/index.js:11:7

Please provide the environment you discovered this bug in

No response

Anything else?

I'm not sure why this happens and if this is an issue with Spectator or Angular's builder. What the builder does is simply building the whole app then running Jest ESM by invoking a node process (code here), so why are we outside of the "Jest test environment"?

An easy fix might be using import.meta.jest instead of importing jest as mentioned in the Jest ESM documentation.
