年前面sybaseQA的几道比试题（寻答案 最好说说理由 谢谢）
1Why is test automation important?
2The following is a pseudocode fragment that has no redeeming feature
except for the purpose of this question.（下面语句是一段伪代码）
module nonsense[]
/*a[] and b[] are global variables */
begin
int i,x
i=1
read(x)
while(i<x)do begin
a[i]=b[i]*x
if a[i]>50 then
print("array a is over the limit")
else
print("ok")
i=i+1
end
print("end of nonsense")
end
Please list test cases to cover all branches in this fragment
（请设计一个测试用例涵盖该段代码各个分支）
3 Describe criterions that testing is completed（描述一个测试结束的准则）
4 What kinds of content should be included in a Test Plan?(For example,
available human resource)（在一个测试计划中能包含哪些内容，如可用的人力资源）
5 Please describe differences between functional testing and usability
testing(请描述功能测试和可用性测试之间的区别)

题目还是自己做。或至少把你的解答写出来大家讨论。
