Instructions for usage with Vitest don't work for me

[FlinnBurgess]

Hello, I've been helping my team switch from Jest to Vitest, and I noticed that I was getting a lot of type errors along the lines of Property toBeInTheDocument does not exist on type JestMatchers<HTMLElement>. After a little digging I realised I could fix it by replacing

import '@testing-library/jest-dom/vitest';

with

import '@testing-library/jest-dom'

in my vitest.setup.ts file.
This seems be the opposite of the instructions on the npm page, so I'm wondering if this is a side effect of me doing something else wrong?

I have the same issue.

Have a read-through of #567 (comment) it might help.

@andykenward I already have my vitest.setup.ts file included in the tsconfig.json. Sadly still not working, unless I use import '@testing-library/jest-dom'.

Got it working on my end. I needed to ensure that our monorepo didn't have conflicting vitest version.

What package manager are you using for your monorepo? npm / yarn / pnpm ?
