RobotFrameWork（四）变量运算与Evaluate

一、特殊变量运算：

执行结果：

Starting test: Robot Demo.Demo.test
20161115 10:14:49.949 : INFO : ${数字变量运算} = 8 20161115 10:14:49.950 : INFO :${布尔类型true运算} = 4
20161115 10:14:49.951 : INFO : ${布尔类型false运算} = 0 20161115 10:14:49.952 : INFO :${space运算} =
Ending test: Robot Demo.Demo.test

二、Evaluate使用
函数释义：Evaluate是执行python表达式，并返回执行结果

示例1：

执行结果：
Starting test: Robot Demo.Demo.test4-2
20161115 10:32:08.674 : INFO : ${var1} = 4 20161115 10:32:08.675 : INFO :${var2} = 8
20161115 10:32:08.677 : INFO : ${var1+var2} = 12 20161115 10:32:08.678 : INFO :${var1-var2} = -4
20161115 10:32:08.679 : INFO : ${var1*var2} = 32 20161115 10:32:08.680 : INFO :${var1/var2} = 0
Ending test: Robot Demo.Demo.test4-2

示例2：

执行结果：
Starting test: Robot Demo.Demo.Python表达式运算
20161115 11:16:42.100 : INFO : ${result} = 3.14 20161115 11:16:42.101 : INFO :${status} = True
20161115 11:16:42.102 : INFO : ${向下取整} = 3 20161115 11:16:42.103 : INFO :${向上取整} = 4.0
