课程复习：通过这几节课的学习，我知道了什么是node，edge，edge pair；明白了什么是分支覆盖和边界值，初步能够能据不同情况分析边界值。
作业：1.P63 7
1）control flow graph
2）令MAXPRIMES=3，t2 = （n = 5）数组越界，而t1 = （n = 3）不会越界。
3）通过edge（2，12），即可不经过while循环，n=1。
4）点覆盖：{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16}
边覆盖：{（1,2），（2,3），（2,12），（3,4），（4,5），（5，6），（6,7），（6,8），（7,5），（8,9），（5,9），
（9,10），（9,11），（10,11），（11,2），（12,13），（13,14），（14,15），（15,13）， （13,16）}

2. Junit进行主路径覆盖测试
