expect(triggerDragEnd).toBeDefined() でその場で定義済みであることを確認済みにもかかわらず、直後で ?. のオプショナルチェーンを使っています。定義済みが保証された変数に対して不要な ?. を使うと、将来的に expect ガードが削除された場合でも ?. が残り、呼び出しがサイレントにスキップされるリスクがあります。

Comment:
`expect(triggerDragEnd).toBeDefined()` でその場で定義済みであることを確認済みにもかかわらず、直後で `?.` のオプショナルチェーンを使っています。定義済みが保証された変数に対して不要な `?.` を使うと、将来的に `expect` ガードが削除された場合でも `?.` が残り、呼び出しがサイレントにスキップされるリスクがあります。
```suggestion
const triggerDragEnd = (window as WindowWithMock).triggerDragEnd;
expect(triggerDragEnd).toBeDefined();
// Drag 'avatar' to 'right' column
triggerDragEnd!({

Code Review
This pull request refactors the LayoutEditor.test.tsx file to improve type safety by replacing any type assertions with a custom WindowWithMock interface and implementing optional chaining for the triggerDragEnd mock. A review comment correctly identifies that the removal of the @testing-library/jest-dom import will cause test failures, as custom matchers like toBeInTheDocument() are still being utilized in the file.

The import of @testing-library/jest-dom was removed, but the tests still use custom matchers like toBeInTheDocument() (e.g., line 85). According to the repository's general rules, this import is the standard way to extend expect with these matchers in this project.
| import "@testing-library/jest-dom"; |
References
- In this repository, importing @testing-library/jest-dom in a Vitest test file is sufficient to extend expect with its matchers; expect.extend is not required.

Superseded by #299, which keeps the same LayoutEditor test cleanup scope with passing checks and no active review threads.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. |

Replaced occurrences of
anytypes and removed the corresponding// eslint-disable-next-line @typescript-eslint/no-explicit-anybypasses insrc/components/__tests__/LayoutEditor.test.tsx. A customWindowWithMocktype was introduced to accurately represent the mocked properties (triggerDragEndandmockIsOverId) attached to thewindowobject during testing. Also,triggerDragEndwas changed to correctly type its arguments.Removing
anyensures TypeScript's static type checking is fully effective, preventing runtime errors caused by mismatched properties or unexpected types. The custom interface centralizes the mock structure, making it self-documenting and easier for future developers to understand and maintain without relying on eslint bypasses.Ran
npx vitest run src/components/__tests__/LayoutEditor.test.tsxto verify all tests continue to pass. Rannpx tsc --noEmitandnpx eslint src/components/__tests__/LayoutEditor.test.tsxto ensure there are no remaining TypeScript or linting errors.The file is now type-safe, free of eslint disables, and maintains the exact same test coverage and logic.

Greptile Summary
テストファイル
LayoutEditor.test.tsxからany型キャストと対応する ESLint 無効化コメントを除去し、windowオブジェクトのモックプロパティを正確に表現するWindowWithMockカスタム型を導入するコードヘルス改善 PR です。グローバルセットアップ (vitest.setup.ts) で既にインポートされている@testing-library/jest-domのローカル重複インポートも合わせて削除されています。(window as any)を(window as WindowWithMock)に置き換え、triggerDragEndとmockIsOverIdに対する型安全性を確保。triggerDragEndの型をオプショナル (?:) にしたことで、呼び出し側がすべて?.のオプショナルチェーンに変更されています。Confidence Score: 5/5
テストロジックに変更はなく、型の精度を高めるリファクタリングのみ。安全にマージ可能です。
変更はすべてテストファイル内の型付け改善に限定されており、プロダクションコードへの影響はありません。
@testing-library/jest-domのローカルインポート削除もグローバルセットアップで補完されているため問題なし。特に注意が必要なファイルはありません。
Important Files Changed
anyキャストをWindowWithMock型に置き換え、ESLint 無効化コメントと冗長なローカルインポートを削除。実質的なロジック変更なし。Flowchart
