🎯 What: The testing gap for the useCardSettings hook in src/hooks/useCardSettings.ts has been addressed by providing a comprehensive test suite.
📊 Coverage: The new tests cover initial state hydration from storage, conditional hydration handling (when not mounted), settings persistence on change, and accurate testing for block and display options toggling and visibility queries.
Result: A significant improvement in test coverage that increases the overall codebase reliability.

Greptile Summary

useCardSettings の初期化、永続化、表示切り替え、可視性照会を対象とするテストスイートを追加しています。

  • ストレージからの初期状態読み込みと設定変更時の保存を検証
  • メインブロックおよび表示オプションの切り替えを検証
  • ブロック可視性の照会を検証
  • 未マウント時のテストは追加されたものの、副作用の抑止を直接検証していません

Confidence Score: 4/5

本番コードは変更されておらずマージを妨げる問題はありませんが、未マウント時の副作用ガードを直接検証するアサーションの追加を推奨します。

追加テストのうち未マウント時のケースは、初期化時にも得られるレイアウトだけを確認するため、hydration や persistence が誤って実行される回帰を検出できません。

### Issue 1
src/hooks/__tests__/useCardSettings.test.ts:52
**未マウント時の副作用を未検証**

このアサーションは `useState` の初期化だけで成立するため、`mounted` ガードが壊れて hydration や persistence が実行されてもテストが成功します。`loadCardSettings` の呼び出し回数と `saveCardSettings` が呼ばれないことを検証し、未マウント時のライフサイクル契約を直接保護してください。

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

PR Summary by Qodo

Add comprehensive test coverage for useCardSettings hook

🧪 Tests 🕐 10-20 Minutes

Grey Divider

AI Description

• Add a dedicated Vitest suite validating useCardSettings hydration and persistence behavior.
• Cover layout visibility toggles, display option toggles, and block visibility queries.
• Mock storage/layout helpers to unit-test hook behavior deterministically.

High-Level Assessment

The following are alternative approaches to this PR:

1. Integration-style tests using real localStorage
  • ➕ Covers loadCardSettings/saveCardSettings behavior end-to-end (including serialization/normalization).
  • ➕ Reduces reliance on implementation-aware mocks (fewer false positives).
  • ➖ More brittle if storage keys/defaults change; requires careful localStorage cleanup between tests.
  • ➖ May be slower and less focused than pure hook unit tests.

Recommendation: The current unit-test approach (mocking load/save + layout utilities) is appropriate for validating hook behavior and edge cases deterministically. If regressions have occurred around serialization/default-merging or storage normalization, consider adding one additional integration test that exercises real localStorage with loadCardSettings/saveCardSettings to complement these unit tests.

Add Vitest coverage for useCardSettings hydration, persistence, and toggles

• Introduces a jsdom-based Vitest suite for useCardSettings. Mocks cardSettings and cardLayout helpers to verify initial state hydration, mounted gating, persistence calls on state changes, block visibility toggling, display option toggling, and isBlockVisible() behavior for known/unknown blocks.

Code Review by Qodo

🐞 Bugs (1) 📘 Rule violations (1) 📜 Skill insights (0)

Grey Divider


Remediation recommended

1. Relative import of useCardSettings 📘 Rule violation ✧ Quality
Description
The new test imports useCardSettings via a relative path even though the target module is under
src/, which should be imported using the @/ alias. This can lead to inconsistent import patterns
and brittle refactors across the src tree.
Code

src/hooks/tests/useCardSettings.test.ts[4]

+import { useCardSettings } from "../useCardSettings";
Evidence
PR Compliance ID 226103 requires that imports targeting modules inside src/ use the @/ alias
rather than relative paths. The added test file imports useCardSettings using
../useCardSettings, which resolves within src/hooks/ and therefore violates the rule.

Rule 226103: Use @/ path alias for src imports in frontend code
src/hooks/tests/useCardSettings.test.ts[4-4]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
A frontend `src/` import uses a relative path (`../useCardSettings`) instead of the required `@/` alias.

## Issue Context
The repository already uses `@/` alias imports in this file (e.g., `@/lib/cardSettings`), so `useCardSettings` should also be imported via `@/` to match the project rule and avoid deep relative paths.

2. Brittle save effect assertion 🐞 Bug ☼ Reliability
Description
useCardSettings only calls saveCardSettings after the hydration useEffect sets
isHydrated=true, but the test asserts saveCardSettings immediately after renderHook without
waiting for that two-effect sequence to complete. This makes the test dependent on Testing Library’s
internal effect-flushing behavior and can become flaky or start emitting act warnings if the hook’s
hydration/persist timing changes.
Code

src/hooks/tests/useCardSettings.test.ts[R55-60]

+  it("should save settings when layout or options change", () => {
+    const { result } = renderHook(() => useCardSettings(true));
+
+    // Initially called on mount due to useEffect persistence
+    expect(saveCardSettings).toHaveBeenCalledWith(mockLayout, mockOptions);
+
Evidence
The hook persists settings only when mounted && isHydrated; isHydrated is set in a separate
hydration effect after mount. Therefore, the first saveCardSettings call is not guaranteed to have
happened at the instant renderHook returns unless the test runner flushes all passive effects and
subsequent updates synchronously.

src/hooks/useCardSettings.ts[19-43]
src/hooks/tests/useCardSettings.test.ts[55-71]
src/hooks/tests/useCardPreview.test.ts[120-134]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
The test asserts `saveCardSettings` synchronously right after `renderHook`, but the hook persists only after hydration completes (`isHydrated` becomes `true`). Make the test explicitly wait for the expected call(s) so it’s robust to React effect scheduling and future hook changes.

### Issue Context
`useCardSettings` performs hydration in a `useEffect`, then persists in a second `useEffect` gated by `isHydrated`.

### Fix Focus Areas
- src/hooks/__tests__/useCardSettings.test.ts[2-3]
- src/hooks/__tests__/useCardSettings.test.ts[55-71]

### Suggested change
- Import `waitFor` from `@testing-library/react`.
- Make the test `async` and use:
 - `await waitFor(() => expect(saveCardSettings).toHaveBeenCalledWith(mockLayout, mockOptions))`
 - after state updates, `await waitFor(() => expect(saveCardSettings).toHaveBeenCalledWith(...))`
This aligns with existing hook tests that wait for effect-driven updates.
