Summary by CodeRabbit

  • Chores

    • Updated development tooling, including Vitest, Vite, and the React plugin, to newer versions.
    • Improved test configuration to exclude generated build output.
  • Tests

    • Improved test stability by disabling concurrency where needed and standardizing mock setup.
    • Updated benchmark suites to use current Vitest benchmarking APIs.
    • Reformatted integration tests without changing their behavior.

Closes COSMO-429

Summary

  • Upgrade Vitest and coverage to v5.
  • Upgrade Vite and the React plugin: Vitest 5 requires Vite 6.4+.
  • Migrate removed test and benchmark APIs; exclude compiled CLI tests.
  • Pin eslint-plugin-import and eslint-module-utils: lockfile re-resolution selected incompatible newer versions that break existing ESLint rules.
  • Rebuild the Go-embedded playground HTML.
  • Moved the affected test mocks outside their test groups because Vitest 5 requires mocks to be set up before tests run.
  • Replaced describe.sequential, which Vitest 5 removed; normal test groups already run one test at a time unless marked concurrent.
  • Updated benchmarks to Vitest 5's test-context API so both cases run as one comparison; the code being measured is unchanged.
  • Corrected three ClickHouse mock paths so the tests use their mock client instead of attempting a real ClickHouse connection.

Validation

  • pnpm -r build
  • pnpm -r --if-present lint
  • CLI, composition, CDN, shared, studio, and protographic tests
  • Protographic benchmarks
  • pnpm --dir controlplane exec tsc -p tsconfig.test.json
  • pnpm --dir playground build:router and make start-router; playground loaded successfully

Controlplane integration tests exceed the local Postgres client limit.

Checklist

Walkthrough

The workspace updates to Vitest 5, adjusts Vite tooling, migrates benchmarks to the current API, updates test syntax, and moves ClickHouse mocks to module scope.

Changes

Vitest migration

Layer / File(s) Summary
Tooling and configuration updates
cli/vite.config.ts, pnpm-workspace.yaml, client-tests/*/package.json, playground/package.json, studio/package.json
Vitest, coverage, Vite, React plugin, and ESLint catalog versions are updated. The Vitest configuration excludes dist/**.
Benchmark API migration
protographic/tests/sdl-to-mapping/sdl-to-mapping.bench.ts, protographic/tests/sdl-to-proto/sdl-to-proto.bench.ts
SDL benchmarks use Vitest test callbacks and bench.compare for simple and complex schema compilation.
Test syntax updates
controlplane/test/delete-user.test.ts, controlplane/test/openai-graphql.test.ts
The delete-user suite disables concurrent execution. OpenAI GraphQL tests use inline timeout arguments.
Module-scope mock initialization
controlplane/test/federated-graph/*.test.ts, controlplane/test/monograph/*.test.ts, controlplane/test/organization/get-organization-by-slug.test.ts, controlplane/test/router/compatibility-version/list.test.ts
ClickHouse mocks move to module scope, and affected mock paths target the imported module.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to fa89e

This updates the test toolchain to Vitest 5, but the unresolved lockfile mismatch can cause npm-based installs to retain Vitest 3 and break the migrated test setup. The benchmark typing concern also remains open; resolve both before merging.
