Add anything to this file that you want run before each test.

If you use the default vitest config value for globals and you want to use jest-dom:

import matchers from '@testing-library/jest-dom/matchers'
import { expect } from 'vitest'

expect.extend(matchers)

    

If you want jest-dom and use globals: true in your config:

import '@testing-library/jest-dom'

    

If you’re using Remix:

import { installGlobals } from '@remix-run/node/globals'
installGlobals()
