接口的实现

个人负责输出接口以及文件操作及文件名筛选部分的实现，为达到松散耦合的编码目的，我们小组对数据进行封装然后在不同接口间传输。

主要思路

• 在分析参数的过程中，将输出信息与文件句柄存在一个结构体里，并将可能存在的多个结构体存到一个数组里，由print函数接收并解析数组，依次根据句柄打开文件并写入信息。
• 将要输出到屏幕上的信息也包成数组送到print函数中，再进行统一输出
• 解析文件名,重载TraversalDir()处理打开多个文件可能有后缀的情况，如果有后缀，就使用过滤器filter，过滤掉不符合条件的文件

测试原理

白盒测试

白盒测试的测试方法有代码检查法、静态结构分析法、静态质量度量法、逻辑覆盖法、基本路径测试法、域测试、符号测试、路径覆盖和程序变异。 白盒测试法的覆盖标准有逻辑覆盖、循环覆盖和基本路径测试。其中逻辑覆盖包括语句覆盖、判定覆盖、条件覆盖、判定/条件覆盖、条件组合覆盖和路径覆盖。六种覆盖标准发现错误的能力呈由弱到强的变化：

• 语句覆盖每条语句至少执行一次。
• 判定覆盖每个判定的每个分支至少执行一次。
• 条件覆盖每个判定的每个条件应取到各种可能的值。
• 判定/条件覆盖同时满足判定覆盖条件覆盖。
• 条件组合覆盖每个判定中各条件的每一种组合至少出现一次。
• 路径覆盖使程序中每一条可能的路径至少执行一次。

然而遗憾的是我负责的部分对白盒测试 不太适合
为了学习， 我特意去测试了一下输入控制模块 如下：

黑盒测试

对于输出可暂且划为四个等价类
