Declare Jmeter variable from a property value

Question

How can I declare a variable name by using the value of a property?

For example, I have the property propertyName with the value propertyValue. I want to declare a variable with the name propertyValue.

I've tried like ${${__P(variableName)}} but such constructions doesnt work.

Answer 1

You may need to evaluate the property name, using the ${__V()} function.

Thus, you'd probably end up with something like ${__V(${__P(propertyName)})} which would only declare a variable with a null value.

Basics on properties & command line:

if you need to pass variables through the command line, properties are indeed the correct choice.

The flag to set a property is -JpropertyName The function to read a property is ${__P(propertyName)}
