Code Review
This pull request adds a new unit test to verify that the GET endpoint for the dashboard summary API returns a 500 status code when authentication fails. The reviewer suggested refactoring the mock implementation of getAuthenticatedUser to use an async function with an explicit return type instead of mockRejectedValueOnce to improve type safety and readability.

Following the repository's general rules, mock implementations returning Promises should use async functions with explicit return types to maintain type safety and readability.
| vi.mocked(getAuthenticatedUser).mockRejectedValueOnce(new Error("Auth failed")); | |
| vi.mocked(getAuthenticatedUser).mockImplementationOnce(async (): Promise<never> => { throw new Error("Auth failed"); }); |
References
- In TypeScript, ensure functions and mock implementations have explicit return types and use async functions for mocks returning Promises to maintain type safety and readability.

🎯 What: The testing gap in
src/app/api/dashboard/summary/route.tswheregetAuthenticatedUserthrowing an error was not tested.📊 Coverage: Added a test that mocks
getAuthenticatedUserto throw an error and asserts that the API correctly handles it and returns a 500 status code with the error message.✨ Result: Improved test coverage by covering the error handling path for user authentication failures.

Greptile Summary
このPRは
src/app/api/dashboard/summary/route.tsに対して、getAuthenticatedUserが例外をスローした場合のエラーハンドリングパスをテストする新しいケースを追加します。getAuthenticatedUserがError("Auth failed")をスローするようにモックし、レスポンスのステータスが 500 でありdata.errorが"Auth failed"であることをアサートする。mockRejectedValueOnce+await import("./route")+response.json()）と完全に整合しており、handleErrorResponseの実装とも正確に一致している。Confidence Score: 5/5
テストのみの変更でありプロダクションコードへの影響はなく、安全にマージできる。
追加されたテストは
handleErrorResponseの実装（error.messageをそのまま返す）と正確に一致したアサートを持ち、既存テストと同一のパターンに従っている。ロジックの誤りや副作用はない。特に注意が必要なファイルはない。
