Vitest fails with TypeError: Unknown file extension ".jsx"

[aminya]

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.

Im not alone, yes!
I have a stackblitz here that reproduces it and it's fairly minimal, only adding one file ontop of the solidstart vitest template.

Did you ever manage to fix it?

[aminya]

No, I could not fix the issue, but I added a production in #158 as well. I talked to @ryansolid about this. He mentioned that @atk created the testing part of the plugin.

[atk]

It is really hard to keep up with the constant changes, so I'm sorry, but I have no fast solution.

[aminya]

Does #158 help you debug the issue?

[NexRX]

I'm working around this with the experimental vitest feature 'browser mode' so no fast solutions needed personally :)

I'm on MacOS and use PNPM. preserveSymlinks: true seems to fix the problem for me, YMMV.

import { defineConfig } from "vitest/config";
export default defineConfig({
  resolve: {
    preserveSymlinks: true,
  },
});
