[MSW] Failed to execute setupWorker in a non-browser environment.

[dsathyakumar]

Hello 👋
I'm on Jest ^27 and msw latest.
My test env is jsdom. However, upon using setupWorker, I get

[MSW] Failed to execute `setupWorker` in a non-browser environment. . Consider using `setupServer` for Node.js environment instead.

I was assuming this would work as it was in a jsdom env.
Please let me know how this can be resolved.

Hey, @dsathyakumar.

The error you get is correct: you shouldn't be using setupWorker in Jest. Jest is a Node.js process, regardless of jsdom-environment (that only controls applied polyfills).

Please use setupServer whenever you want to run MSW in Node.js.
