v4.0.0

👀 Highlights

We're releasing Nuxt Test Utils v4, with support for Vitest v4. 🚀

Better mocking support

The biggest improvement in this release is how mocking works. Nuxt initialization has been moved from setupFiles to the beforeAll hook (#​1516), which means vi.mock and mockNuxtImport calls now take effect before Nuxt starts. This fixes a long-standing issue where mocks for composables used in middleware or plugins wouldn't apply reliably (#​750, #​836, #​1496).

On top of that, mockNuxtImport now passes the original implementation to the factory function (#​1552), making partial mocking much more natural:

mockNuxtImport('useRoute', original => vi.fn(original))

it('my test', async () => {
  vi.mocked(useRoute).mockImplementation(
    (...args) => ({ ...vi.mocked(useRoute).getMockImplementation()!(...args), path: '/mocked' }),
  )

  const wrapper = await mountSuspended(MyComponent)
  expect(wrapper.find('#path').text()).toBe('/mocked')
})

registerEndpoint improvements

registerEndpoint now works correctly with query parameters in URLs (#​1560), and endpoints registered in setup files are no longer lost when modules reset (#​1549).

🚧 Migration

@nuxt/test-utils v4 contains a few breaking changes, almost all related to requiring at least vitest v4 as a peer dependency (if you are using vitest). It replaces vite-node with Vite's native Module Runner and simplifies pool configuration.

This will mean improvements for test performance and mocking, but does require some changes to your test code.

[!TIP]
Most of the changes below are straightforward. The biggest thing to watch out for is code that runs at the top level of a describe block — see below.

Update your dependencies

Update vitest and its companion packages together:

{
  "devDependencies": {
-   "@nuxt/test-utils": "^3.x",
-   "vitest": "^3.x",
-   "@vitest/coverage-v8": "^3.x"
+   "@nuxt/test-utils": "^4.0",
+   "vitest": "^4.0",
+   "@vitest/coverage-v8": "^4.0"
  }
}

Peer dependencies

We've tightened peer dependency ranges. You may need to update some of these:

Dependency	v3	v4
vitest	^3.2.0	^4.0.2
happy-dom	*	>=20.0.11
jsdom	*	>=27.4.0
@jest/globals	^29.5.0 || >=30.0.0	>=30.0.0
@cucumber/cucumber	^10.3.1 || >=11.0.0	>=11.0.0
@testing-library/vue	^7.0.0 || ^8.0.1	^8.0.1

Later environment setup

This is the change that might require most change in your tests. Because we've moved the nuxt environment setup into beforeAll, this means composables called at the top level of a describe block will fail with [nuxt] instance unavailable.

// Before (worked in vitest v3)
describe('my test', () => {
  const router = useRouter() // ran lazily, after environment setup
  // ...
})

// After (vitest v4)
describe('my test', () => {
  let router: ReturnType<typeof useRouter>

  beforeAll(() => {
    router = useRouter() // runs after environment setup
  })
  // ...
})

This applies to useRouter(), useNuxtApp(), useRoute(), and any other Nuxt composable or auto-import.

[!TIP]
If you only need the value within individual tests, beforeEach or directly within the test works too.

Stricter mock exports

If you use vi.mock with a factory function, accessing an export that the factory doesn't return will now throw an error instead of silently returning undefined.

// Before: accessing `bar` would silently return undefined
vi.mock('./module', () => ({ foo: 'mocked' }))

// After: accessing `bar` throws
// Fix: use importOriginal to include all exports
vi.mock('./module', async (importOriginal) => ({
  ...await importOriginal(),
  foo: 'mocked',
}))

[!NOTE]
If you're mocking a virtual module (like #build/nuxt.config.mjs) where importOriginal can't resolve the real module, you might need to explicitly list all accessed exports in your mock factory.
