Version

29.4.1

Steps to reproduce

  1. Clone my repo https://github.com/rumblefishdev/jest-reproduce-import-bug
  2. npm i
  3. npm run test

Expected behavior

You should see

(node:376068) ExperimentalWarning: VM Modules is an experimental feature. This feature could change at any time
(Use `node --trace-warnings ...` to show where the warning was created)
 PASS  src/index.test.ts
  describe
    ✓ run main (12 ms)

Test Suites: 1 passed, 1 total

Actual behavior


> [email protected] test
> NODE_OPTIONS=--experimental-vm-modules node_modules/.bin/jest src/index.test.ts

 FAIL  src/index.test.ts

Additional context

If you edit node_modules/iso-constants/index.js file like:

'use strict';

-module.exports = require('constants');
+const c = require('constants');
+module.exports = c;

and re-run the tests, stuff works fine and you the expected output.

I believe that the problem origins in this line: https://github.com/facebook/jest/blob/main/packages/jest-runtime/src/index.ts#L954
In here it should be caling this._resolver.isCoreModule(modulePath) and acting accordingly.

This is why patching index.js to replace re-export with normal export fixes the problem.

@SimenB I've attached a pull request. I tested this using the example repository I've attached and it fixes the problem with a particular package that was giving me a headache.
I wish I knew how to add a testcase for such scenario.
