Code Review
This pull request introduces a comprehensive test suite for the ActionButtons component in src/components/__tests__/ActionButtons.test.tsx, covering rendering, click interactions, disabled states, and conditional text based on copy status. Additionally, src/components/ActionButtons.tsx has been added to the Vitest configuration file. There are no review comments, and I have no feedback to provide.

beforeEach をインポートに追加する
globals: true によりグローバルとして動作しますが、他のユーティリティ（describe、it、expect、vi）と同様に明示的にインポートすることで、コードの一貫性と可読性が向上します。

previewUrl が null の場合にボタンが disabled になることは確認していますが、disabled 状態でクリックしても handleCopy / handleDownload が呼ばれないことのテストがありません。fireEvent.click は disabled 属性を無視して onClick を呼び出すため、disabled 時にハンドラを実行しないという保証が現在のテストでは得られていません。

🎯 What: The
ActionButtonscomponent lacked unit tests, creating a testing gap. Added comprehensive tests using React Testing Library and Vitest, and updatedvitest.config.tsto include it in coverage tracking.📊 Coverage: Covered rendering states, click handlers (
handleCopy,handleDownload), conditional button disabling whenpreviewUrlis null, and correct rendering of text/icons based oncopyStatus.✨ Result: Improved test coverage and reliability for the application UI.

Greptile Summary
このPRは
ActionButtonsコンポーネントのユニットテストを追加し、vitest.config.tsのカバレッジ対象にも追加しています。ActionButtons.test.tsx): レンダリング確認、クリックハンドラの呼び出し検証、previewUrl=null時の disabled 状態、copyStatusによる表示切替の6ケースをカバー。vitest.config.ts): カバレッジincludeリストにActionButtons.tsxを1行追加するだけのシンプルな変更。Confidence Score: 4/5
テスト追加と設定の1行変更のみで、既存の動作コードには一切手を加えていないため、マージしても安全です。
テストファイルは主要なシナリオを正しくカバーしており、コンポーネントの実装とも整合しています。
beforeEachの未インポートや disabled ボタンのクリック挙動が未検証という軽微な指摘はありますが、いずれも既存機能を壊すものではありません。ActionButtons.test.tsxのbeforeEachインポートと disabled 状態のクリックテストを確認すると良いでしょう。Important Files Changed
