🧹 [code health improvement] Remove any cast in LayoutEditor.test.tsx#298
Conversation
🎯 **What:** Removed instances of `(window as any)` and related `eslint-disable-next-line` comments in `LayoutEditor.test.tsx`. 💡 **Why:** Relying on `any` bypasses TypeScript's type checking, making the code more error-prone and harder to understand. By defining an explicit `MockWindow` interface, we clearly specify the expected shape of the mocked properties on the window object. This improves type safety and removes the need for eslint suppression comments. ✅ **Verification:** Ran `npm run lint` and `npm run test src/components/__tests__/LayoutEditor.test.tsx`. The tests pass and there are no linting errors related to this file. ✨ **Result:** A cleaner, safer test file with properly typed mock window access.

Code Review
This pull request improves type safety in the LayoutEditor tests by replacing any casts and ESLint overrides with a MockWindow interface and double-casting. The reviewer suggests using global augmentation to extend the Window interface instead, which would eliminate the need for repetitive casting and improve code readability throughout the test file.
| interface MockWindow { | ||
| triggerDragEnd?: (event: unknown) => void; | ||
| mockIsOverId?: string; | ||
| } |

Instead of defining a local interface and using repetitive double-casting (as unknown as MockWindow), you can use global augmentation to extend the Window interface. This is more idiomatic in TypeScript for test files and significantly improves code readability by allowing direct access to these properties on the window object.
| interface MockWindow { | |
| 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; |

Remove the redundant cast now that the Window interface is augmented.

| window.triggerDragEnd = onDragEnd; |

Superseded by #299, which keeps the same LayoutEditor test cleanup scope with passing checks and no active review threads.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
テストファイル
LayoutEditor.test.tsx内のwindow as anyキャストを、新たに定義したMockWindowインターフェースを使ったwindow as unknown as MockWindowに置き換えた型安全化リファクタリングです。eslint-disable-next-line @typescript-eslint/no-explicit-anyコメントも同時に削除されています。MockWindowインターフェースにtriggerDragEnd?とmockIsOverId?の2つのオプションプロパティを定義し、全8箇所のanyキャストを置換。Confidence Score: 5/5
テストファイルのみを変更する純粋な型安全化リファクタリングであり、ロジックの変更は一切ない。マージに問題はない。
変更は
anyキャストを明示的なMockWindowインターフェースに置き換えるものに留まり、テスト動作・アサーション・モック実装はすべて変更前と同一。!非nullアサーションは既存のexpect(triggerDragEnd).toBeDefined()チェックと組み合わせて適切に使用されており、型エラーや実行時の問題を引き起こすリスクはない。特に注意が必要なファイルはない。
