Upgrades Vitest from 4.1.4 to 5.0.0 across the monorepo, fixes the
handful of things v5 turned into hard errors, and drops the
`vi.clearAllMocks()` boilerplate that v5's `clearMocks` default makes
redundant.
**Changed:**
- `vitest`, `@vitest/ui`, `@vitest/coverage-v8` 4.1.4 → 5.0.0 (catalog)
- `vi.mock` calls that lived inside `beforeAll`/`beforeEach`/test bodies
moved to module scope (v5 throws on nested calls). Affects the Studio
and docs setup files and four Studio tests.
- `detectBrowser` test restores `navigator` via `vi.unstubAllGlobals()`
instead of assigning `global.navigator`, which now reaches jsdom's
getter-only property.
- `RowEditor.utils.test.ts` restores its `JSON.stringify` spy. It used
to leak a throwing mock for the rest of the file, which v5's coverage
provider now trips over. A later test in the same file had been
asserting the leak's side effect (valid JSON reported as invalid) and
now asserts the correct behavior.
- `@testing-library/jest-dom` 6.6 → 7.0.1. Its vitest type augmentation
resolves through a peer now, so it lands on each package's own `vitest`
instead of whichever copy pnpm hoisted. Fixes `toBeInTheDocument` type
errors in dev-tools after the reshuffle.
- `@testing-library/react` 16.0.0 → 16.3.3 for the React 19 peer range.
- `vite: catalog:` added to dev-tools, www, and common. Without it they
resolved a newer vite than the catalog pin, which forked a second vitest
instance in the lockfile. There's now one.
- ai-commands custom matcher types use v5's `Matchers<R, T>` form.
- 110 test files: `vi.clearAllMocks()` removed from
`beforeEach`/`afterEach` hooks, along with hooks that only did that and
the imports they left unused. Calls that also reset/restore mocks are
untouched. Second commit, mechanical.
**Added:**
- `.vitest/` to the root gitignore (v5 writes JSON/JUnit/HTML reporter
output there)
**Removed:**
- `vite-tsconfig-paths` catalog entry and deps. Vitest 5 resolves
tsconfig paths itself.
Release-age note: this sat in draft with a temporary
`minimumReleaseAgeExclude` entry for `vitest` and `@vitest/*` while
5.0.0 was inside the workspace's 3-day `minimumReleaseAge` window. That
window has closed, so the exclusion is gone and nothing bypasses the
release-age gate.
**Perf** (local, medians of 3 runs, same machine):
| Suite | v4.1.4 | v5.0.0 |
|---|---|---|
| studio | 144.1s | 141.7s (-2%) |
| studio `--coverage` | 156.9s | 146.4s (-7%) |
| ui-patterns | 6.27s | 5.07s (-19%) |
| ui `--coverage` | 3.35s | 2.14s (-36%) |
| www | 0.89s | 0.47s (-47%) |
Studio is dominated by jsdom environment setup per file, which v5
doesn't change. `vitest doctor` recommends keeping the current pool
config: the vm pools and `isolate: false` all break tests.
## To test
- `pnpm install --frozen-lockfile` succeeds with no
`minimumReleaseAgeExclude` entry for vitest.
- CI: Studio unit tests, ui, ui-patterns, www, docs, and typecheck/lint
should all be green. The lint ratchet was checked locally: warning
counts on touched Studio files are identical to master.
- `pnpm test:studio` locally passes with coverage (588 files, 6240
tests).
- Open a Studio test that uses `toBeInTheDocument` in your editor and
confirm no type errors on jest-dom matchers, in Studio and in
`packages/dev-tools`.
- Known pre-existing failures unrelated to this PR: one dev-tools test
(`getEventCountBadge` capped pill) fails on master too.

The `Update JS Client Libraries Docs` workflow's "Refresh
reference-content snapshot" step fails because `npx vitest run --update
scripts/build-reference-content.test.ts` is treated as a filter, not a
restriction, under Vitest 4, so all docs tests
run. `CodeSample.test.ts` then fails with ENOENT on
`apps/docs/examples/_internal/fixtures/*` because the workflow bypasses
the `pretest` npm hook that runs `codegen:examples`.
This is a regression of #44943 (commit 28ef62cf31), reintroduced by
#46163 when the snapshot step was renamed and rewritten back to the
file-path form.
Fixes:
- Workflow: use `--dir scripts` so only the snapshot test runs.
- Tests: add a vitest globalSetup that mirrors `codegen:examples`, so
`npx vitest`, `pnpm test:local`, and IDE single-test runs no longer
depend on the `pretest` lifecycle hook being triggered first.

## Summary by CodeRabbit
* **Chores**
* Updated test infrastructure configuration and initialization process
for improved test suite management.
* Refined test execution workflow to efficiently manage test discovery
and execution across project directories.
<!-- end of auto-generated comment: release notes by coderabbit.ai -->
Tests get spammed with unnecessary tsconfig errors because the Vitest
config tries to use tsconfig files from the examples directory.
Excluding those from tsConfigPaths for cleaner test output.
* feat(content api): add error endpoint
Add an endpoint to return the details of a Supabase error, given the
error code and service.
Schema additions:
```graphql
type RootQueryType {
"...previous root queries"
"""Get the details of an error code returned from a Supabase service"""
error(code: String!, service: Service!): Error
}
"""An error returned by a Supabase service"""
type Error {
"""
The unique code identifying the error. The code is stable, and can be used for string matching during error handling.
"""
code: String!
"""The Supabase service that returns this error."""
service: Service!
"""The HTTP status code returned with this error."""
httpStatusCode: Int
"""
A human-readable message describing the error. The message is not stable, and should not be used for string matching during error handling. Use the code instead.
"""
message: String
}
enum Service {
AUTH
REALTIME
STORAGE
}
```
* test(content api): add tests for top-level query `error`
The examples folder needs to be explicitly included in the Vercel Serverless bundle. Because it's at the root of the monorepo rather than being within the `app/docs` folder, we copy it over pre-build (and pre-dev).
Test the examples/prompts fix by re-enabling revalidations on graphql pages. Added a temp version of the fetch function so we can gradually reenable and monitor Vercel error rates over time.
This produces more complete type information (unions, following type alias refererences that aren't successfully dereferenced at an earlier stage, etc.), in a format that is much easier to query from UI components. Also adds a snapshot test for easier future iteration.
I had a lot of trouble configuring Jest for the snapshot tests (something to do with imports and compile targets), and there are zero other tests in this directory right now, so I just tore out the test setup and replaced it with Vitest. Much faster!
