- Around line 19-22: Update vitestMajor and importVitestEnvironments to detect
and use vite-plus/test/runtime when available, deriving the Vitest major version
from vite-plus’s declared dependency so Vitest 5 cleanup behavior is preserved;
retain the existing Vitest resolution path as the fallback.
Review comments at @src/module/plugins/mock.ts:
- Around line 102-103: Update the `hasViImport` handling for `VITEST_SOURCES` so
an aliased import such as `vi as testVi` does not suppress the generated `vi`
binding unless generated mock setup calls are also changed to use the imported
local name. Keep the existing behavior for an unaliased `vi` import.

vite-plus 1.3 package.json bundled vitest runtime vite-plus/test
💡 Result:
For **Vite+ 1.3.0**, you can import Vitest APIs from `vite-plus/test`; Vite+ documents that its package re-exports **Vitest 5.0.5**, so a separate `vitest` dependency isn’t required just to use those APIs. ([viteplus.dev](https://viteplus.dev/guide/migrate?utm_source=openai))
```ts
import { describe, expect, it } from 'vite-plus/test'
```
For a project `package.json`, use `vite-plus` and run tests with `vp test`. If other dependencies in your project also resolve Vitest, Vite+ recommends pinning `vitest` to the bundled version to avoid loading mismatched Vitest copies. ([viteplus.dev](https://www.viteplus.dev/guide/test?utm_source=openai))
The sources establish the supported import and bundled version; they don’t show the exact published `vite-plus@1.3.0` manifest here.

exsolve resolveModulePath from option import.meta.url package resolution documentation
💡 Result:
`exsolve`’s `resolveModulePath(id, options)` resolves a module to an **absolute filesystem path**. The `from` option sets where resolution starts; it accepts a URL, path, or array of either. If omitted, resolution starts from the current working directory. ([github.com](https://github.com/unjs/exsolve/blob/main/README.md?utm_source=openai))
To resolve relative to the current module—similar to `import.meta.resolve()`—pass `import.meta.url`:
```js
import { resolveModulePath } from "exsolve";
const path = resolveModulePath("some-package", {
from: import.meta.url,
});
```
The docs recommend setting `from` explicitly. For better performance, use a `file://` URL or a path ending in `/`; an absolute path without a trailing slash requires a filesystem check to determine whether it represents a file or directory. ([github.com](https://github.com/unjs/exsolve/blob/main/README.md?utm_source=openai))
`resolveModulePath` returns a path, not a URL, and throws if the resolved URL isn’t a `file://` URL. If you need the URL form, use `resolveModuleURL`. ([github.com](https://github.com/unjs/exsolve/blob/main/README.md?utm_source=openai))

vite-plus@1.3.0 package.json dependencies vitest package exports vite-plus/test
💡 Result:
For **`vite-plus@1.3.0`**:
- **Vitest:** The release bundles **Vitest 5.0.5**. Vite+ documents that its `vite-plus/test*` imports re-export Vitest APIs. ([github.com](https://github.com/voidzero-dev/vite-plus/releases?utm_source=openai))
- **`vite-plus/test`:** It’s a supported import path—for example, `import { describe, expect, it } from 'vite-plus/test'`. ([viteplus.dev](https://www.viteplus.dev/guide/test?utm_source=openai))
The sources I found establish the bundled version and supported import, but don’t show the **1.3.0 package’s exact `package.json` dependency and `exports` entries**. So I can’t confirm the precise manifest field or export-map shape from them.

site:github.com/voidzero-dev/vite-plus/issues/1506 vite-plus vitest runtime Nuxt test-utils getPackageInfo
💡 Result:
Issue **#1506** is a feature request for better Vite+ integration with Nuxt and Astro—not specifically about a Vitest runtime error or `getPackageInfo`. It proposes reading Vite+ config from framework config files and having `vp dev`/`vp build` invoke the appropriate framework commands. (GitHub issue 1506 in voidzero-dev/vite-plus (link omitted to avoid creating a cross-reference))
For Nuxt tests, a related Vite+ discussion recommends keeping `vitest.config.ts` with `@nuxt/test-utils/config` and running the package’s `vitest` script via `vp run test`; Vite+’s built-in `vp test` reads the `test` block from `vite.config.ts`. That discussion doesn’t establish whether `getPackageInfo` is involved in your runtime issue. (GitHub discussion 2367 in voidzero-dev/vite-plus (link omitted to avoid creating a cross-reference))

🌐 Web query:
vite-plus 1.3 test/runtime populateGlobal dist/test/runtime.js vitest runtime export
💡 Result:
Yes—**Vite+ 1.3.0 provides a Vitest runtime subpath**. The Vite+ migration guide maps Vitest’s `vitest/environments` and `vitest/snapshot` imports to `vite-plus/test/runtime`, and says Vite+ re-exports upstream Vitest. ([viteplus.dev](https://www.viteplus.dev/guide/vitest-v5?utm_source=openai))
Vitest documents `populateGlobal` as an export of `vitest/runtime`, so the corresponding Vite+ import is:
```ts
import { populateGlobal } from 'vite-plus/test/runtime'
```
That import path is an inference from Vite+’s re-export mapping and Vitest’s documented runtime export. I couldn’t verify the exact `vite-plus@1.3.0` published `dist/test/runtime.js` or its export map, so that specific file-level detail remains unconfirmed.

Resolve Vite+ through vite-plus/test/runtime.
vite-plus@1.3.0 keeps Vitest 5.0.5 as a nested dependency. It exposes the supported runtime as vite-plus/test/runtime, not as vitest/runtime.
The changed lookups start from @nuxt/test-utils and request the bare vitest package. In an isolated install, that path cannot reach vite-plus/node_modules/vitest. vitestMajor becomes NaN, and the fallback imports vitest/environments. Nuxt environment startup can then fail under vp test.
Use the Vite+ runtime when it is available, and use its declared Vitest version for the Vitest 5 cleanup behavior.

📚 Description
this makes
@nuxt/test-utilswork with Vite+ (vp test) in a project that only depends onvite-plus, without a directvitestdependency.with
vite-plusv1.3 (which bundles Vitest 5), anuxtenvironment test would fail to start like this:this is because the environment detects the Vitest version with
getPackageInfo('vitest'), which resolves fromprocess.cwd()- and with novitest, it returns nothing ...... and we also add support for
import { vi } from 'vite-plus/test'.
