How to set and get environment variables in Jmeter to test API's

I need to set and get variables in Jmeter for API automation.

I am using the groovy script for same.

I have achieved same using code as below:

import org.apache.jmeter.util.JMeterUtils;

JMeterUtils.setProperty("PC_CREATED_PROMO_CODE", "shubhamvalue");

log.info("will it work? ="+JMeterUtils.getProperty("PC_CREATED_PROMO_CODE"))

Now the problem is I am not able to see the value in any contanier where I can set my hardcode values like token, baseURL, Headers. it should be similar we do in SOAP-UI or postman tests.

Please let me know if I can see these setProperty values in file/section/container in Jmeter.

Or suggest me any other workaround which is more feasible for same.

enter image description here

Any workaround will be helpful and appreciated in advance.

In JMeter, you can set and get environment variables using the built-in functions and properties. Environment variables in JMeter are often referred to as JMeter properties.

Setting Environment Variables (Properties):

1.Setting Variables in JMeter GUI:

  • Open your JMeter test plan in the JMeter GUI.
  • Right click the test plan, then select Add > Config Element > User Defined Variables
  • Add a new variable with the desired name and value.

2.Setting Properties in JMeter Script:

  • You can set properties in your JMeter script using the __setProperty function. For example, to set a property named myVar with a value of 123:
${__setProperty(myVar, 123)}
  • Place this in a BeanShell PreProcessor, JSR223 Sampler, or use it in a Beanshell assertion where needed.

Getting Environment Variables (Properties):

1.Getting Variables in JMeter GUI:

  • You can get the value of a variable in your JMete using ${variable_name}

2.Getting Properties in Beanshell or JSR223 Script:

  • In a Beanshell or JSR223 script, you can use the following to get the value:
String myVarValue = props.get("myVar");

If you need to get and set variables I would recommend using vars shorthand

As per documentation

Properties are not the same as variables. Variables are local to a thread; properties are common to all threads, and need to be referenced using the __P or __property function.

So I would suggest setting variables as: vars.put('foo', 'bar') and accessing them as ${foo} where required as my expectation is that you will be getting different PC_CREATED_PROMO_CODE for each thread (virtual user)

Also be aware that it is also recommended to avoid scripting where possible so consider going for JSON Extractor instead.

1) In JMeter GUI mode, under WorkBench, create Property Display by WorkBench > Add > Non-Test Elements > Property Display. Then select JMeter Properties checkbox to view all the exist properties

props.put("shubhamKey", "shubhamValue")

When you execute this code the property will set in a property file and you can see it in below location:

WorkBench > Add > Non-Test Elements > Property Display.

2) Now if you are want to use User Defined Variables in your scripts you can call value like below:

vars.get("shubhamUserKey")

Still looking to set the value from code in User Defined Variables
