接口的實現

個人負責輸出接口以及文件操作及文件名篩選部分的實現，為達到松散耦合的編碼目的，我們小組對數據進行封裝然後在不同接口間傳輸。

主要思路

• 在分析參數的過程中，將輸出信息與文件句柄存在一個結構體裏，並將可能存在的多個結構體存到一個數組裏，由print函數接收並解析數組，依次根據句柄打開文件並寫入信息。
• 將要輸出到屏幕上的信息也包成數組送到print函數中，再進行統一輸出
• 解析文件名,重載TraversalDir()處理打開多個文件可能有後綴的情況，如果有後綴，就使用過濾器filter，過濾掉不符合條件的文件

測試用例的設計

測試原理

白盒測試

白盒測試的測試方法有代碼檢查法、靜態結構分析法、靜態質量度量法、邏輯覆蓋法、基本路徑測試法、域測試、符號測試、路徑覆蓋和程序變異。 白盒測試法的覆蓋標準有邏輯覆蓋、循環覆蓋和基本路徑測試。其中邏輯覆蓋包括語句覆蓋、判定覆蓋、條件覆蓋、判定/條件覆蓋、條件組合覆蓋和路徑覆蓋。六種覆蓋標準發現錯誤的能力呈由弱到強的變化：

• 語句覆蓋每條語句至少執行一次。
• 判定覆蓋每個判定的每個分支至少執行一次。
• 條件覆蓋每個判定的每個條件應取到各種可能的值。
• 判定/條件覆蓋同時滿足判定覆蓋條件覆蓋。
• 條件組合覆蓋每個判定中各條件的每一種組合至少出現一次。
• 路徑覆蓋使程序中每一條可能的路徑至少執行一次。

然而遺憾的是我負責的部分對白盒測試 不太適合
為了學習， 我特意去測試了一下輸入控制模塊 如下：

黑盒測試

對於輸出可暫且劃為四個等價類
