How to enable es6 import modules in Jest in a ESM used back-end

Question

I'm using a NodeJs backend with ESM package enabled mode to use es6+ import modules system when I'm trying to access a file in my test, even if I use require in my test file because target file uses import/export, it throws this error:

SyntaxError: Cannot use import statement outside a module

I know, I can use babel to solve Jest problem, but due to my main project files (which are using ESM), is there any solution to config Jest with ESM?

Does this answer your question? [Node v13 / Jest / ES6 — native support for modules without babel or esm](https://stackoverflow.com/questions/60372790/node-v13-jest-es6-native-support-for-modules-without-babel-or-esm) — Nino Filiu, May 07 '20 at 08:32

I have a good news to you. Jest supports esm natively from version 25.4.0. It is not documented yet, but I wrote here, how to achieve that.

I hope, it will help to you.

Thank you, but I haven't enough reputation to do that :/ – Radovan Kuka May 07 '20 at 08:41
