Bump @nuxt/test-utils from 3.23.0 to 4.0.0

[dependabot]

Bumps @nuxt/test-utils from 3.23.0 to 4.0.0.

Release notes

Sourced from @​nuxt/test-utils's releases.

v4.0.0

4.0.0 is the next major release.

👀 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",
</tr></table>
