setting testEnvironment to node causes jest functions to be undefined

[alyhegazy]

🐛 Bug Report

When setting testEnvironment to node and running a test I get ReferenceError: test is not defined. If I remove testEnvironment: 'node' from the config it runs fine. The same applies to describe, beforeAll...etc.

Note: it works fine on node 10.16.0

 FAIL  test/1.test.js
  ● Test suite failed to run

    ReferenceError: test is not defined

    > 1 | test('test1', () => {
        | ^
      2 |   expect(1).toBe(1);
      3 | });

      at Object.<anonymous> (test/1.test.js:1:1)

To Reproduce

Steps to reproduce the behavior:

jest.config.js

module.exports = {
  testEnvironment: 'node'
}

test/1.test.js

test('test1', () => {
  expect(1).toBe(1);
});

Expected behavior

Tests should run without errors when testEnvironment is set to node.

Jest itself sets it to node in our own tests, so your reproduction is not enough. Can you put together a repository or a repl/codesandbox

[alyhegazy]

Here's a simple test https://github.com/alyhegazy/jest-tests-bug.git
I get the error in the description on node 10.14.0

[SimenB]

Right, that's a bug in node 10.14.0 and 10.14.1 (possibly earlier as well, didn't check) - 10.14.2 (and newer) works correctly. Fix is nodejs/node#23206.

(duplicate of #9453)

Damn, I wasted one whole day :|
10.14.2 worked! Thanks a lot!

[alyhegazy]

Tell me about it!

[manwithsteelnerves]

@alyhegazy What you want to know?

[uloga]

Wasted few hours on this. :( Thanks for the fix.

I've published 25.2.2 which has a workaround for this issue on the buggy versions of node

[enuchi]

Thanks for this -- had issues using 10.13.0. Seems like jest 26 no longer works with node 10.13, but downgrading to 25.2.2 does. Any way to get 26 to support the buggy versions of node?

[thymikee]

@enuchi Jest 26 requires Node >=10.14.2

[SimenB]

Precisely because of this issue

[enuchi]

Cool. Thanks!

This was such a stupid big and I spent nearly 1 hour exploring it.
