發現錯誤是好事

It's better to catch a bug at design time than at coding/compile time. It's better to catch a bug at coding/compile time than during unit testing. It's better to catch a bug during unit testing than during debug system testing. It's better to catch a bug during debug system than in prerelease/beta system testing. It's better to catch a bug during prerelease/beta system testing than have your customer catch one. It's better to have your customer catch a bug than to have no customers.

在設計時發現錯誤總比在編碼編譯時發現好。 在編碼編譯時發現錯誤總比在單元測試中發現好。 在單元測試中發現錯誤總比在調試中發現好。 在調試中發現錯誤總比在系統測試中發現好。 在系統測試中發現錯誤總比讓用戶發現好。 讓用戶發現錯誤總比沒有用戶好。
