为printPrimes()方法画控制流程图:

技术分享

  

  c) 针对printPrimes(),寻找一个测试用例,让响应的测试路径访问while语句开始到for语句的边t3=(n=0)(或者n=1)

 

  d) 

    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]

      [4,5,6,3,7,9,1,10,11,12] 

      [4,5,6,3,7,8,9,1,10,11,12]

      [2,3,7,8,9,1,10,11,12]

      [2,3,7,8,9,1,10,13]

      [4,5,6,3,7,8,9,1,2]

      [7,8,9,1,2,3,4,5,6]

      [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]

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

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

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

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

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

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

      [3,7,9,1,2,3]*

      [4,5,6,3,4]*

      [5,6,3,4,5]*

      [6,3,4,5,6]*

      [3,4,6,3]*

      [4,6,3,4]*

      [6,3,4,6]*

      [10,11,12,10]*

      [11,12,10,11]*

      [12,10,11,12]*

      }
