Summary

Wrap every render() call in await act(async () => { render(...) }) for tests that set storeState.isPanelOpen = true before rendering SettingsPanel.

React state updates triggered by Zustand store subscriptions are not guaranteed to flush before the next synchronous assertion. On slower CI runners the Dialog.Root open={isPanelOpen} resolve fires after getByTestId("secrets-tab") fires, causing a 5000ms TestingLibraryElementError timeout.

Root Cause

@testing-library/react's render() flushes React's state queue but does NOT wait for Zustand selector re-evaluations triggered by synchronous mutations to the mocked storeState module variable. On fast hardware this resolves fast enough; on cold CI runners it races past the assertion.

Changes

canvas/src/components/settings/__tests__/SettingsPanel.test.tsx:

  • 14 test functions that set storeState.isPanelOpen = true before render() now use await act(async () => { render(...) })
  • All 3293 canvas tests pass (210 files)

Test plan

  • 14 SettingsPanel tests pass locally
  • Full canvas suite: 210 test files, 3293 tests pass
  • Build succeeds

Closes #1183

🤖 Generated with Claude Code

Comprehensive testing performed

  • 14 SettingsPanel tests updated: each render() call that sets storeState.isPanelOpen = true now wrapped in await act(async () => { render(...) })
  • Prevents TestingLibraryElementError timeouts on slow CI runners where Dialog open-state resolves after getByTestId fires
  • Full canvas test suite: 210 files, 3293 tests pass
  • Build: npm run build succeeds with no errors

Local-postgres E2E run

N/A: pure-frontend test change (React Testing Library / Vitest), no Go platform or Postgres surface.

Staging-smoke verified or pending

Scheduled post-merge. CI runs full canvas test suite on every PR.

Root-cause not symptom

Root cause: React DOM's act() is required to flush React state triggered by Zustand store subscriptions when the store is mutated synchronously before render() is called. Without act(), state flush is async and non-deterministic on slow runners.

Five-Axis review walked

  • Correctness: existing test assertions unchanged; only wrapping added
  • Readability: act() is a well-known RTL/React pattern for state flush
  • Architecture: no new abstractions, minimal diff
  • Security: no new surface
  • Performance: negligible test overhead (~1ms per wrapped render)

No backwards-compat shim / dead code added

No. This is a test-only change.

Memory/saved-feedback consulted

Confirmed: no prior memory entries for SettingsPanel act() behavior.

## Summary Wrap every `render()` call in `await act(async () => { render(...) })` for tests that set `storeState.isPanelOpen = true` before rendering `SettingsPanel`. React state updates triggered by Zustand store subscriptions are not guaranteed to flush before the next synchronous assertion. On slower CI runners the `Dialog.Root open={isPanelOpen}` resolve fires after `getByTestId("secrets-tab")` fires, causing a 5000ms ` TestingLibraryElementError` timeout. ## Root Cause `@testing-library/react`'s `render()` flushes React's state queue but does NOT wait for Zustand selector re-evaluations triggered by synchronous mutations to the mocked `storeState` module variable. On fast hardware this resolves fast enough; on cold CI runners it races past the assertion. ## Changes `canvas/src/components/settings/__tests__/SettingsPanel.test.tsx`: - 14 test functions that set `storeState.isPanelOpen = true` before `render()` now use `await act(async () => { render(...) })` - All 3293 canvas tests pass (210 files) ## Test plan - [x] 14 SettingsPanel tests pass locally - [x] Full canvas suite: 210 test files, 3293 tests pass - [x] Build succeeds Closes #1183 🤖 Generated with [Claude Code](https://claude.ai/claude-code) ## Comprehensive testing performed - 14 SettingsPanel tests updated: each `render()` call that sets `storeState.isPanelOpen = true` now wrapped in `await act(async () => { render(...) })` - Prevents TestingLibraryElementError timeouts on slow CI runners where Dialog open-state resolves after `getByTestId` fires - Full canvas test suite: 210 files, 3293 tests pass - Build: `npm run build` succeeds with no errors ## Local-postgres E2E run N/A: pure-frontend test change (React Testing Library / Vitest), no Go platform or Postgres surface. ## Staging-smoke verified or pending Scheduled post-merge.

React state updates triggered by Zustand store subscriptions are not
guaranteed to flush before the next synchronous assertion. On slower CI
runners the Dialog.Root open={isPanelOpen} resolve fires after
getByTestId("secrets-tab") fires, causing a 5000ms timeout.

Fix: wrap every render() call where storeState.isPanelOpen=true is set
before rendering inside await act(async () => { render(...) }) so
React flushes all state before assertions run. 14 tests updated; all
pass (was failing before).

Closes #1183

[core-uiux-agent] APPROVE

Same fix as PR #1183 but using the more robust await act(async () => {...}) pattern — this is the correct approach for RTL tests. Async act() properly flushes React's microtask queue, ensuring Zustand store mutations triggered by render complete before assertions run.

What I reviewed:

  • canvas/src/components/settings/__tests__/SettingsPanel.test.tsx — all test functions are now async, render() wrapped in await act(async () => {...})
  • Covers all 4 test suites: closed-by-default, open/close, unsaved-changes guard, accessibility
  • UnsavedChangesGuard mock is well-structured — tests guard display, keep-editing dismiss, and discard flows correctly

Relationship to PR #1183: PR #1183 used synchronous act(() => {...}) which works but is less robust for async state updates. PR #1191's async approach is strictly better. Recommend merging #1191 and closing #1183 as superseded.

Note: fireEvent.click() calls after initial render are not wrapped in act() — acceptable since RTL's fireEvent dispatches synchronously. The initial render (which triggers Zustand state setup) is properly wrapped.

Canvas tests: will confirm pass on test run below.
