Unable to get a running env with nuxt/test-utils

[joesobo]

Environment

- Operating System: `Darwin`
- Node Version:     `v16.16.0`
- Nuxt Version:     `3.0.0-rc.11`
- Nitro Version:    `0.5.4`
- Package Manager:  `yarn@1.22.11`
- Builder:          `vite`

Though I have also tested with rc 10, 8, 5, & 4

Reproduction

This is fairly short so ill avoid reproduction unless theres a strong need

From a fresh Nuxt 3 Project:

// package.json

{
  "scripts": {
    ...
    "build": "nuxt build",
    "test": "vitest run"
  },
  "devDependencies": {
    "nuxt": "3.0.0-rc.11"
  },
  "dependencies": {
    "@nuxt/test-utils": "3.0.0-rc.11",
    "vitest": "^0.23.4"
  }
}

// vite.config.ts

import { defineConfig } from "vitest/config";

export default defineConfig({
  test: {
    globals: true,
  },
});

// pages/index.vue

<template>
  <h1>Hello World!</h1>
</template>

// pages/index.spec.ts

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

describe('My test', async () => {
  await setup({
    runner: 'vitest',
  })

  test('my test', () => {
    const html = $fetch('/')

    expect(html).toContain('Hello World!')
  })
})

Describe the bug

During the beforeAll section of the setup in my test it crashes with this result:

Error: [vite]: Rollup failed to resolve import "jest" from "node_modules/@nuxt/test-utils/dist/index.mjs".
This is most likely unintended because it can break your application at runtime.
If you do want to externalize this module explicitly add it to
`build.rollupOptions.external`

This is strange since the runner is clearly vitest, so it shouldnt be trying to import jest.

Took a brief look at the index.mjs and my hooks.ctx.options.runner is properly recieving vitest.

The error ends with:

 Segmentfault Error Detected 
  FATAL ERROR: v8::ToLocalChecked Empty MaybeLocal.
  Refer to https://github.com/nodejs/node/issues/42407

Additional context

I havent been able to find a solid working example to base my own code. I was hoping this issue was just the RC version that I was using, but so far I havent had any luck with changing it.

I tried cloning the nuxt-ionic repository as I saw it was on a later RC version and using vitest, however even with that I ran into issues. Is there a good working example I can be pointed in the direction of?

It seems to be an upstream bug of Node.js. To improve the test stability,
you could pass --segfault-retry=3 or set env VITEST_SEGFAULT_RETRY=3 to
have Vitest auto retries on flaky segfaults.

With that repro I can't actually reproduce your error. If you're still experiencing it, would you provide a reproduction? 🙏

[joesobo]

Thanks for getting back to me on this @danielroe!

I just tested it out and it seems like the issue I was running into was due to colocating my tests within the pages/ dir. Works as expected when I move all tests out into another dir like tests/

[danielroe]

Great. You may find that adding the test pattern to ignore in your config also resolves the issue for you.

[noook]

@danielroe Where exactly would you put that piece of config ?

I'm having this issue when my spec file is in the pages directory

edit: I found out it was in nuxt config, but actually I have this issue when I run the tests

[DengSihan]

Same issue here. It may be caused by the wrong location of your test file just as @noook mentioned.

To test SSR pages/index.vue

describe('index page', async () => {
    await setup();
    test('should has a title', async () => {
        const htmlString = await $fetch('/');
        console.log(htmlString);
    });
});

Minimum issue reproduction: locate this file as pages/index.spec.js

How to fix: pages/index.spec.js -> tests/{anywhere}/index.spec.js
