Cannot redefine property: window (>=v19.7.0) #47310
Description
Activity
Do you have a test case using only the vm module? Your bug report is unlikely to get attention if it depends on a big third-party module like jsdom.
Since I'm not familiar with the inner workings of jsdom I cannot remove that as a dependency. All I can do is provide simple exact repro steps:
- Save below snippet as test.js.
- Run
npm i jest jest-environment-jsdom - Run
npx jest
/** * @jest-environment jsdom */ "use strict" global.window = {};Since the issue is reproducible with the snippet above on node version 19.7.0 but not on 19.6.1 I think there have been a breaking change somewhere between these two versions in node.
This was possibly fixed by aa6e9c8
Can you try with the latest nigthly?Works fine with latest nightly.
I also tested with a nightly before the mentioned commit (from March 17) and there it's failing. But on v20.0.0-nightly20230405f6f3e22016 it's passed.
Awesome, thank you very much.
I'm closing the ticket.
