Reference a variable within a variable in JMeter

Question

I'm working with JMeter. I'd like to specify the test host using user defined variables, like this: ``` variable name value localhost localhost test 192.168.0.1 hostname ${localhost} ``` Executing the test, I see that the hostname value is not substituted, and obviously the test fails. I know I can use properties and pass the hostname from the command line, or simply change the hostname value. Is it possible to it like I've explained? Thanks.

Accepted Answer

I've managed to solve my problem. I've changed the hostname variable value to: `${__evalVar(${localhost})}`, but I've got this error:

ERRROR jmeter.functions.EvalVarFunction: Variables have not yet been defined

So I've moved the hostname variable declaration in a "User defined variable" child node of my Sampler node. That solved it.
