🎯 Changes

Three suspense tests in useQuery.test.ts did not assert what suspense() settles with:

  • should resolve after being enabled: only checked a flag set by the test's own setTimeout. It now uses a mock queryFn and an onResolve spy on suspense(), and asserts neither is called while disabled, then that suspense() resolves with data: 'Some data' once enabled becomes true.
  • should not throw from suspense by default: never called suspense(). It now asserts suspense() resolves with status: 'error'.
  • should throw from suspense when throwOnError is true: passed a vi.fn() returning undefined, so throwOnError was effectively false. It now returns true and asserts suspense() rejects with 'Some error'. The error watcher also throws in this case, so the resulting unhandled rejection in Vue 3 is suppressed with noop.

Timers are unified to sleep(10) / advanceTimersByTimeAsync(10).

✅ Checklist

  • I have followed the steps in the Contributing guide.
  • I have tested code changes locally with pnpm run test:pr, or these tests do not apply to this pull request.
  • I fully understand the code in this pull request, including any code generated with AI assistance.

🚀 Release Impact

  • This change affects published code, and I have generated a changeset.
  • This change is docs/CI/dev-only (no release).

Summary by CodeRabbit

  • Tests
    • Suspense tests now wait for queries to resolve after they are enabled, await the default error-state result, and verify rejection when throwOnError is enabled.
    • Rejection tests now safely handle unhandled-rejection notifications during test cleanup. These changes update automated checks only; no user-facing functionality changes are included.

📝 Walkthrough

Walkthrough

The Vue Query suspense tests now assert promise resolution and rejection directly. They adjust timer advancement and install a temporary unhandledRejection listener for the throwOnError case.

Layer / File(s) Summary
Suspense promise assertions
packages/vue-query/src/__tests__/useQuery.test.ts
Tests assert that suspense remains unresolved while disabled, resolves after enabling, resolves to an error state by default, and rejects when throwOnError returns true.

Merge Risk: 🔵 Low · up to b455f

This test can hide an unrelated unhandled rejection while it runs, though its listener is removed even if the test fails. The risk is limited to the test suite.

verifies the expected Vue watcher rejection instead of swallowing every
rejection; install and remove the listener in a try/finally block so it is
removed even if Promise.all rejects.
