JMeter - 某些功能无法在功能助手

关于JMeter功能助手对话框，它是一个很棒的工具，但是当期望变量可用时，某些功能无法使用它来执行

__split函数具有强制变量名称抛出异常，例如在调用${__split(a,a,)}

时

函数__isVarDefined也会出现NullPointerException：

JMeter 4中的新函数__isVarDefined也会出现NullPointerException：

JMeter是否应该在函数助手中初始化变量，或者它是否无关紧要，因此需要在没有变量上下文的情况下添加一个不可用的警告？

1 个答案:

答案 0 :(得分：1)

在函数助手对话框中通常无法测试的函数需要一些上下文：

  • 属性设置
  • 设置变量 ...

这是在以下增强中确定的限制：

如果您有任何想法，请随意提供补丁，例如：

  • 可以创建一个空的JMeterVariable
  • 用户可以输入一些Groovy代码以填写此对象或其他属性的文本区域

这样任何功能都可以测试。
