🧹 [Code Health Improvement] Remove any types in ThemeController.test.tsx

[is0692vs]

🎯 What: Removed this: any and @typescript-eslint/no-explicit-any comments in the FastAverageColor mock, and replaced colorLib.adjustAccentColor as any with vi.mocked.
💡 Why: Ensures strict type checking is preserved and avoids the use of any types and eslint-disable comments, improving maintainability and readability.
✅ Verification: Executed npm run test and npm run lint on the file to confirm behavior remained consistent with no type errors or broken assertions.
✨ Result: A cleaner, strictly typed mock implementation.

Greptile Summary

テストファイル ThemeController.test.tsx から any 型と eslint-disable コメントを除去するコードヘルス改善 PR です。FastAverageColor モックでは this: any パターンを plain オブジェクト返却に変更し、colorLib.adjustAccentColor への型キャストを vi.mocked() に置き換えています。

• FastAverageColor のコンストラクタモックを this: any 方式からオブジェクトリターン方式に変更（new 式ではどちらも同等の動作）
• (colorLib.adjustAccentColor as any).mockImplementation(...) を Vitest 推奨の vi.mocked(colorLib.adjustAccentColor).mockImplementation(...) に置き換え、型推論が正確に働くよう改善

Confidence Score: 5/5

変更はテストファイルのみで、any キャストを型安全な API に置き換えるだけの限定的な修正。

FastAverageColor モックのオブジェクトリターン方式は new 式の仕様上、元の this 方式と同等に動作します。vi.mocked() への移行も Vitest の推奨パターン通りです。テストロジックや実装コードへの影響はなく、型安全性のみが向上しています。

特に注目が必要なファイルはありません。

Code Review

This pull request refactors the test mocks in ThemeController.test.tsx to improve type safety and remove ESLint suppressions by utilizing vi.mocked and returning object literals instead of using any casts. Feedback was provided to ensure that the test suite includes coverage for failure scenarios in asynchronous operations, such as rejected promises from getColorAsync, to verify proper error handling.
