How to put value of User Defined Variable into Bean shell Sampler Variable - Jmeter

Question

I try to move a User Defined variable to variable in beanshell sampler. (I need the User defined variable to be part of a bigger string.)

When I try to move it, or make a copy of it I get error 500

can someone please advise how can I put the value of user defined field in bean-shell variable and than use it (not need to change the user defined variable just want it value)

In this script I Want to put the value of $Expected_Offer_ID to String variable Expected_Offer

Answer 1

There are (at least) 2 options:

1. Put ${Expected_Offer_ID} to "Parameter" section of the Sampler. You will be able to access it as Parameters in your script
2. Use vars.get("Expected_Offer_ID); where required. vars is a shorthand to JMeterVariables class instance, it provides read/write access to all JMeter Variables

Remember 2 things:

• Never refer JMeter Variables and/or Functions in the Script body like ${myVar}, either use aforementioned "Parameters" section or code-based equivalents as they might resolve into something which can cause script interpretation failure or unexpected behaviour. Moreover, in case of Groovy language it prevents compiled scripts caching
• Don't use Beanshell for scripting. Since JMeter 3.1 it is recommended to use JSR223 Test Elements and Groovy language as Groovy is more Java-compliant and performs much better. See Apache Groovy - Why and How You Should Use It article for more detailed explanation, benchmarks and some tips on Groovy JDK enhancements usage.
