Research direction

Start with the Solid testing guide linked in the report and the documented Vitest configuration, then reproduce the failure involving the .jsx file under node_modules/@corvu/utils. Done means the documented setup can run the reported TSX component test without the unknown file extension error.

Written by the indexing model from the issue text.

Description

I am trying to test a component using Vitest, but following the documentation fails with this error
https://docs.solidjs.com/guides/testing#adding-testing-packages

TypeError: Unknown file extension ".jsx" for /media/aminya/Linux/GitHub/test/test/node_modules/.pnpm/@corvu+utils@0.2.0_solid-js@1.8.17/node_modules/@corvu/utils/dist/reactivity/index.jsx

My test file is a tsx file. It seems Vitest has trouble loading the .jsx file. My config is the same as the doc.
