软件测试第二次作业：fault,error and failure

1.

1)  Fault: the first element of the array is not in the loop.
2)  If possible, identify a test case that does not execute the fault(Reachability):  x is null.
3)  If possible, identify a test case that executes the fault, but does not result in an error state:  x={5,2,7},y=7.
4)  If possible, identify a test case that results in an error, but not a failure:  x={5,2,7},y=1.

 

2.

1)  Fault: the order is reversed in the loop.
2)  If possible, identify a test case that does not execute the fault(Reachability):  x is null.
3)  If possible, identify a test case that executes the fault, but does not result in an error state:  x={0}.
4)  If possible, identify a test case that results in an error, but not a failure:  x={5,2,7}.
