JMeter If Controller使用groovy和Or无法正常工作 [英] JMeter If Controller using groovy and Or is not working

问题描述

我有一个脚本，其中有一些if控制器.我试图添加第四个If控制器，如果三个预期值均未返回，则该脚本将触发脚本故障.这是说三个期望值之一是无效的.

首先，我有一个用户定义的变量，如下所示:

  testTool = $ {__ P(testTool，APPLES)} 

2nd，我有这3个If控制器，它们具有以下表达式:

1. $ {__ groovy(vars.get("testTool").toUpperCase().equals("APPLES"))}
2. $ {__ groovy(vars.get("testTool").toUpperCase().equals("BANANAS"))}
3. $ {__ groovy(vars.get("testTool").toUpperCase().equals("PEACHES"))}

如果testTool的值不是3个期望值之一，则应该触发第4个If.它的表情看起来像这样:

 >$ {__ groovy((vars.get("testTool").toUpperCase().equals("APPLES")== false ||>vars.get("testTool").toUpperCase().equals("BANANAS")==假||>vars.get("testTool").toUpperCase().equals("PEACHES")== false))} 

我也尝试过这种方式:

 >$ {__ groovy((！vars.get("testTool").toUpperCase().equals("APPLES")||>！vars.get("testTool").toUpperCase().equals("BANANAS")||>！vars.get("testTool").toUpperCase().equals("PEACHES"))，)} 

某种程度上说APPLES是无效的testTool.我究竟做错了什么?所有控制器是否都已选中"解释为变量表达式的条件".

解决方案

您应该使用&& 运算符而不是 || ，请参见

请参见 JMeter轻松创建中的选择语句有关详细信息的指南.

I have a script where I have some if controllers. I'm attempting to add a 4th If controller that will trigger a script failure if none of the 3 expected values is returned. It's saying one of the 3 expected values is invalid.

1st, I have a user defined variable like this:

testTool= ${__P(testTool,APPLES)}

2nd, I have these 3 If controllers with these Expressions:

1. ${__groovy(vars.get("testTool").toUpperCase().equals("APPLES"))}
2. ${__groovy(vars.get("testTool").toUpperCase().equals("BANANAS"))}
3. ${__groovy(vars.get("testTool").toUpperCase().equals("PEACHES"))}

The 4th If is supposed to be triggered if the value of testTool is not one of the 3 expected values. It's Expression looks like this:

>    ${__groovy( (vars.get("testTool").toUpperCase().equals("APPLES") == false || 
>    vars.get("testTool").toUpperCase().equals("BANANAS") == false ||
>    vars.get("testTool").toUpperCase().equals("PEACHES") == false)) }

I have also tried it this way:

>  ${__groovy((!vars.get("testTool").toUpperCase().equals("APPLES") || 
>  !vars.get("testTool").toUpperCase().equals("BANANAS") || 
>  !vars.get("testTool").toUpperCase().equals("PEACHES")),)}

It is somehow saying APPLES is an invalid testTool. What am I doing wrong? All if controllers have the 'Interpret Condition as Variable Expression' checked.

解决方案

You should use && operator instead of ||, see Groovy Logical Operators for detailed explanation and more information.

Your 4th expression needs to be amended to look like:

${__groovy(!(vars.get("testTool").toUpperCase().equals("APPLES")) && !(vars.get("testTool").toUpperCase().equals("BANANAS")) && !(vars.get("testTool").toUpperCase().equals("PEACHES")))}

An easier option would be using Switch Controller, from implementation and especially performance perspectives it is the optimal solution.

• Add Switch Controller to your Test Plan
• Use ${testTool} as the "Switch Value"

• Put 4 requests as the children of the Switch Controller and name them as:

  • APPLES
  • BANANAS
  • PEACHES
  • DEFAULT

  So if ${testTool} variable value will be APPLES - the APPLES sampler will be executed, if ${testTool} variable value will be BANANAS - the BANANAS sampler will be executed, etc.

  If ${testTool} will not match any other children - JMeter will run DEFAULT sampler
