1. 作业要求

  见《软件测试基础》P49,Q7——a)b)c)d)。

 

2. 作业内容

  

  a)为printPrimes()方法画控制流程图

    

  

  b) 考虑测试用例t1=(n=3)和t2=(n=5)。即使这些测试用例游历printPrimes()方法中相同的主路径,他们不一定找出相同的错误。设计一个简单的错误,使得t2比t1更容易发现。

    数组越界问题

  

  c) 针对printPrimes(),找到一个测试用例,使得响应的测试路径访问连接while语句开始到for语句的边,而不用通过while循环体。

    t3=(n=0)(或者n=1)

 

  d) 针对printPrimes()的图例列举每个节点覆盖,边覆盖和主路径覆盖的测试需求。

    节点覆盖:

    TR={0,1,2,3,4,5,6,7,8,9,10,11,12,13}

    

    边覆盖:

    TR={(0,1),(1,2),(2,3),(3,4),(4,5),(4,6),(5,6),(6,3),(3,7),(7,8),(7,9),(8,9),(9,1),(1,10),(10,11),    (10,13),(11,12),(12,10)}

    

    主路径覆盖:

    TR={

      [4,5,6,3,7,9,1,10,13]

      [4,5,6,3,7,8,9,1,10,13]

      [2,3,7,9,1,10,11,12]

      [4,5,6,3,7,9,1,2]

      [7,8,9,1,2,3,4,6]

      [7,9,1,2,3,4,5,6]

      [0,1,2,3,4,5,6]

      [0,1,2,3,7,8,9]

      [7,9,1,2,3,4,6]

      [0,1,10,13]

      [0,1,10,11,12]

      [11,12,10,13]
