"setup" is not exported by "node_modules/unenv/runtime/mock/proxy.mjs"

[alexcroox]

I have the following Nuxt 3 server api test, sat alongside the endpoint file:

import { fetch, setup } from '@nuxt/test-utils/e2e'
import { describe, expect, it } from 'vitest'

describe('signed-url.post', async () => {
  await setup()

  it('should return signed upload url', async () => {
    const response = await fetch('/api/file/v1/signed-url', {
      method: 'POST',
      body: JSON.stringify({
        category: 'profile',
        name: 'test.jpg',
        sizeBytes: 1000,
        mimeType: 'image/jpeg'
      })
    })

and the following vitest config:

import { defineVitestConfig } from '@nuxt/test-utils/config'

export default defineVitestConfig({
 test: {
   include: ['./**/*.test.ts'],
   exclude: [
     './node_modules',
     './dist',
     './automation',
     './.wrangler',
     './.nuxt',
     './coverage',
     './playwright-report',
     './tests/e2e',
     './**/*.e2e.spec.ts'
   ]
 }
})

The beforeAll part of the test never completes and errors after about 20 seconds with:

I can't work out why this is triggering the error:

"setup" is not exported by "node_modules/unenv/runtime/mock/proxy.mjs", imported by "src/server/api/file/v1/signed-url.post.test.ts".
1: import { $fetch, setup } from '@nuxt/test-utils/e2e'

Hey there, @alexcroox! I'm here to assist you with any bugs, questions, or contributions you have. Let's dive in and see how I can help you out!

The error you're encountering is due to the setup function not being exported correctly from the @nuxt/test-utils/e2e module. To resolve this, you should move the await setup() call outside of the describe block. Here is the corrected version of your test file:

import { fileURLToPath } from 'node:url'
import { $fetch, setup } from '@nuxt/test-utils/e2e'
import { describe, expect, it } from 'vitest'

await setup({
  rootDir: fileURLToPath(new URL('../', import.meta.url)),
  dev: true,
})

describe('signed-url.post', () => {
  it('should return signed upload url', async () => {
    const response = await $fetch('/api/file/v1/signed-url', {
      method: 'POST',
      body: JSON.stringify({
        category: 'profile',
        name: 'test.jpg',
        sizeBytes: 1000,
        mimeType: 'image/jpeg'
      })
    })
    // Add your assertions here
  })
})

Make sure to place the await setup call outside of the describe block to ensure the setup is completed before any tests are run ^[1][2].

@alexcroox Were you able to get this working? I'm stuck with this same issue and nothing has worked so far.

[alexcroox]

Afraid not, I gave up trying to unit test the server side of Nuxt a while ago :(

Thank you for responding! Unfortunate, because I'm pretty close to giving up myself. If I do figure this out, I'll post here.
