Conversation
…r.test.tsx 🎯 What: Replaced `(window as any)` with a properly typed `MockWindow` interface extending `Window`, and removed associated `@typescript-eslint/no-explicit-any` comments. Added non-null assertion when assigning the mocked `triggerDragEnd` function to satisfy strict null checks. 💡 Why: Improves type safety in the test suite and removes linter bypasses, making the code more robust and aligned with project standards without altering runtime logic. ✅ Verification: Ran `npm run test` on the modified file to ensure tests pass, and `npm run lint` to verify no new warnings were introduced. Passed strict TypeScript compilation checks. ✨ Result: Clean, strictly typed test mocks with zero `any` usages or disabled linter warnings.

.toBeDefined() チェックが省略されている
最初のドラッグテスト（line 124）では triggerDragEnd! の直後に expect(triggerDragEnd).toBeDefined() が置かれていますが、2 番目以降のテスト（ここを含む計 6 箇所）では同ガードが省略されています。! は TypeScript コンパイル時のみ有効で実行時には何も保証しないため、fireEvent.click(dndContext) が意図通りに機能しなかった場合、triggerDragEnd(...) の呼び出し時に「TypeError: triggerDragEnd is not a function」が発生し、どのアサーションが失敗したか特定しにくくなります。今回の ! 追加に合わせて他テストにも .toBeDefined() ガードを追加しておくと、診断しやすくなります。

Code Review
This pull request improves type safety in the LayoutEditor tests by replacing any casts and ESLint overrides with a dedicated MockWindow interface for window-attached test helpers. The reviewer suggests using global interface augmentation for the Window object to eliminate the need for repeated manual casting, which would further enhance code maintainability and readability.
| interface MockWindow extends Window { | ||
| triggerDragEnd?: (event: unknown) => void; | ||
| mockIsOverId?: string; | ||
| } |

Instead of creating a separate MockWindow interface and casting window repeatedly, you can use TypeScript's interface augmentation to add these properties directly to the global Window object. This approach is cleaner as it allows you to access these properties on window directly without any casting throughout the test file, which aligns better with the goal of improving code health and maintainability.
| interface MockWindow extends Window { | |
| triggerDragEnd?: (event: unknown) => void; | |
| mockIsOverId?: string; | |
| } | |
| declare global { | |
| interface Window { | |
| triggerDragEnd?: (event: unknown) => void; | |
| mockIsOverId?: string; | |
| } | |
| } |
| // Expose a way to trigger onDragEnd via a synthetic event or global for testing | ||
| // We'll attach it to window for easy triggering | ||
| (window as unknown as { triggerDragEnd: (event: unknown) => void }).triggerDragEnd = onDragEnd; | ||
| (window as unknown as MockWindow).triggerDragEnd = onDragEnd; |

With the global interface augmentation suggested above, you can remove the redundant double casting and access the property directly on window.
| (window as unknown as MockWindow).triggerDragEnd = onDragEnd; | |
| window.triggerDragEnd = onDragEnd; |
| setNodeRef: vi.fn(), | ||
| // eslint-disable-next-line @typescript-eslint/no-explicit-any | ||
| isOver: (window as any).mockIsOverId === id, | ||
| isOver: (window as unknown as MockWindow).mockIsOverId === id, |

With the global interface augmentation, this cast is no longer necessary.

Superseded by #299, which keeps the same LayoutEditor test cleanup scope with passing checks and no active review threads. Closing this duplicate to keep the open PR queue actionable. |

Greptile Summary
このPRはテストファイル（
LayoutEditor.test.tsx）のコードヘルス改善のみを対象としており、window as anyキャストをMockWindowインターフェース経由のwindow as unknown as MockWindowに置換し、関連する ESLint 抑制コメントをすべて除去しています。プロダクションコードへの影響はありません。MockWindowインターフェースをモジュールスコープに定義し、triggerDragEndとmockIsOverIdの 2 プロパティをオプショナルで型付け。window as anyを使っていた全箇所をwindow as unknown as MockWindowに統一。triggerDragEnd取得箇所に非 null アサーション（!）を追加し、TypeScript の strict null チェックを満たすよう対応。Confidence Score: 4/5
テストファイルのみを変更しており、プロダクションコードへの影響はありません。型安全性の改善として妥当な変更です。
変更はテストスコープのみで、型キャスト手法を
anyからMockWindowインターフェース経由に切り替えたものです。実行時の動作は変わらず、非 null アサーション（!）の追加も適切です。一部のテストでtoBeDefined()ガードが省略されている点は診断性の軽微な懸念ですが、動作への影響はありません。特に注意が必要なファイルはありません。変更は
LayoutEditor.test.tsxのみで、コードヘルス改善に留まっています。Important Files Changed
