test指令用法举例
Test指令可以简写为[],[]和test是等价的,用法为:[ expression ]。
以下是Test指令的几个用法示例:
1. 数值测试:
* 例子:num1=100 num2=100,if test $[num1] -eq $[num2] then echo '两个数相等! ' else echo '两个数不相等! ' fi。
运行结果:两个数相等!
2. 字符串测试:
* 例子:num1="ru1noob" num2="runoob",if test $num1 = $num2 then echo '两个字符串相等!' else echo '两个字符串不相等!' fi。
输出结果:两个字符串不相等!
3. 文件测试:
* 例子:cd /bin,if test -e ./bash then echo '文件已存在!' else echo '文件不存在!' fi。
输出结果:文件已存在!
4. 寄存器测试:
* Test用来测试一个位,例如寄存器:test eax,100b。
b后缀意为二进制jnz,如果eax右数第三个位为1,jnz将会跳转。
* Test的一个非常普遍的用法是用来测试一方寄存器是否为空:test ecx, ecxjz somewhere,如果ecx为零,设置ZF零标志为1,jz跳转。
以上是Test指令的一些常见用法示例,仅供参考。

软件测试_Pairwise Testing
Pairwise Testing理论
如何测试V2.0这样的应用程序?
步骤6(续):
检查是否所有的“两两”都存在?
其余列组合情况已经检查,不再进行检查
Pairwise Testing理论
如何测试V2.0这样的应用程序?
通过“两两”组合(同时考虑等价类划分)我们 已经极大的减少了测试用例的数量
“Cartesian Products”(笛卡尔积)
给定一组域D1,D2,…,Dn,这些域中可以有 相同的; 所有域的所有取值的一个组合,不能重复; 假设集合A={a,b},集合B={0,1,2},则两个集合的 笛卡尔积为{(a,0),(a,1),(a,2),(b,0),(b,1), (b,2)}。
如何测试V2.0这样的应用程序?
目标
减少测试用例,去除无效的测试用例 使用“等价类”方法,合并变量取值
Pairwise Testing理论
如何测试V2.0这样的应用程序?
步骤1:
列出各种“变量”的所有可能“取值”
Pairwise Testing理论
如何测试V2.0这样的应用程序?
GUI 应用程序 V1.0测试简单,在有限的时间 内能够完成所有的遍历情况; GUI 应用程序 V2.0测试复杂,在有限的时间 内不能够完成所有的遍历情况; 如何测试V2.0这样的应用程序?
Pairwise Testing理论
如何测试V2.0这样的应用程序?
通过简单的观察,我们很容易的发现一个“BUG” :
99个 如果平均每个用例的设计和执行需要一个工时,则 需要浪费的工作量近100个工时,即一个人需要工作 2周半

num sample should be a positive
num sample should be a positive
这句话的意思是:“数字样本应该是正数”。
在编程和数据分析中,我们经常需要确保输入的数据满足某些条件。
在这种情况下,要求数字样本必须是正数。
如果数字不是正数,那么程序或算法可能会抛出错误或返回不正确的结果。
为了确保数字是正数,你可以使用条件语句或逻辑运算符进行检查。
例如,在Python中,你可以这样做:
Pythonnum = some_value # 这里是你要检查的数字
if num > 0:
print("数字是正数")
else:
print("数字不是正数")这段代码会检查变量num是否大于0,如果是,则输出“数字是正数”,否则输出“数字不是正数”。
