题目1
流程图
判定覆盖
需要三条路径
第一组:
- (x,y,z) = (4,0,9)
- (x,y,z) = (4,0,0)
- (x,y,z) = (2,0,0)
第二组:
- (x,y,z) = (4,0,9)
- (x,y,z) = (4,0,0)
- (x,y,z) = (1,0,0)
条件组合覆盖
第一个判断 | 第二个判断 |
---|---|
x>3 z<10 | x==4 y>5 |
x<=3 z<10 | x!=4 y>5 |
x>3 z>=10 | x==4 y<=5 |
x<=3 z>=10 | x!=4 y<=5 |
所以4个组合 |
- (x,y,z)=(4,6,9)
- (x,y,z)=(3,6,9)
- (x,y,z)=(4,5,10)
- (x,y,z)=(3,5,10)
