I am using JMeter and I want to access a variable set in my .bash_profile
Is there any way I can do so.
Yes. You can use Beanshell Pre Processor OR Beanshell Post Processor OR Beanshell Sampler
I tried to access JAVA_HOME, it works fine. Replace JAVA_HOME with your variable.
System.getenv("JAVA_HOME")
To access it in JMeter,
vars.put("JAVAHOME", System.getenv("JAVA_HOME"));
Then in your test use ${JAVAHOME} to get the value.

I need to set and get variables in Jmeter for API automation.
I am using the groovy script for same.
I am able to store key-values in Property Files using below code:
props.put("shubhamKey", "shubhamValue")
I do not want to use the main property as it contains so many other keys which may use by Jmeter and we can't place any hardcode key in property directly.
But I am not an able set similar thing in any of below containers :
User Defined Variables
User Parameters
The code I am trying is as below:
vars.put("shubhamUserKeyagain","shubhamUservalue")
Use vars.put and execute the script and click on User Defined Variables. The new key should reflect there but it's not. That is my main issue
I have tried to place User Parameters just below in TestPlan, With-in the request where JSR223 Assertion is present, also tried to place it before and after JSR223 Assertion
My get value is working fine from these containers but the set is not reflecting over the containers. Below code, I am using to get the value
vars.get("shubhamLocalVariable")
Another code I have tried :
vars.putAll("myNormalValue","changeho")
Is there any other container in which I can set and get key-values using the script as groovy.
Environment :
OS : Window 10
Jmeter Version: 3.2 r1790748
Running bat file as an administrator
I have added my project in below URL:
https://ufile.io/7r6tk
Please refer and let me know if I missed anything
Reference Screenshots:
User Parameter
JSR233 Assertion
This one works for me - I have cleared up your script
I want to parametrize the testdata path, result path, server and port by defining them in environment variable.
I was able to achieve this to certain extent with System.getenv("Jmeter_Result") using it in BeanShell processor. But I need to use configuration element to fetch the value.
Can you kindly suggest.I am using Jmeter 3.1.
According to https://jmeter.apache.org/usermanual/functions.html#what_can_do, ${__BeanShell( ... )} may also help you on this issue.
For instance, one of our APIs needs OAuth2 authentication, and what I did was:
- Thread Group
- User Defined Variables
client_id = ${__BeanShell( System.getenv("client_id") )}
client_secret = ${__BeanShell( System.getenv("client_secret") )}
- Once Only Controller
- OAuth2 HTTP Request
- API HTTP Request
There is __env() function available via JMeter Plugins, it seems to be something you're looking for.
You can install __env() and other custom JMeter Functions using JMeter Plugins Manager.
If the environment variable is made available via a System property then
JMeter can access it using the ${__P("Jmeter_Result")} function.
Otherwise, it's trivial to pass in the value of an environment variable using
the -J option:
jmeter -JJmeter_Result=$Jmeter_Result
I am performing HTTP Request samples (both GET and POST) in JMeter and am trying to figure out how to include pieces of the request (right now, just the query and form parameters) in the CSV log output. It seems like I'll have to use something like BeanShell Listener to write my own log file using the JMeter API. Does that sound right?

Not necessarily. Given your parameters are in form of JMeter Variables (if not - you can convert them via User Defined Variables test element) you can use samples_variable property in order to add values to JMeter's .jtl results file
Add the next line to user.properties file (it's located under /bin folder of your JMeter installation)
sample_variables=var1,var2,etc.
where var1 and var2 are your JMeter Variables
Restart JMeter to pick the property up
Next time you run your test variable values will be added to .jtl results file

I have a custom JMeter sampler, which derives from AbstractJavaSamplerClient. In this sampler, I want to change a user defined variable in the JMeter GUI after the sampler finishes. I can access user defined variables using
JMeterContextService.getContext().getVariables()
but changing values in these variables using the put method does not reflect in the GUI. Is this even possible?
No it's not possible as when you do this, it is on running copy of components.
I've a few BeanShellScripts inside my JMeter Project. I would like to use a few of them inside my project. I'm using command inside BeanShell PreProcessor to invoke another BeanShellProcessor in my project:
${__BeanShell(Name_Of_My_Script)}
But I realized that It's opening them a few times, so sometimes the request is sending with wrong value. Is there any another command or option to do this?
I don't think that it's a right way to execute Beanshell via function. As per JMeter Beanshell manual Beanshell Script attribute should be
A beanshell script (not a file name)
More correct way is storing your another Pre-Processor script code into a JMeter Variable, i.e. SCRIPT2 and call it as ${__BeanShell(${SCRIPT2})}.
You won't need to escape anything as the function automatically parses input script.
See How to use BeanShell guide for more details on Beanshell scripting.
It's working quite well if you use Module Controller which indicate a current Simple Controller with Beanshell script to run. Inside Simple Controller should be BeanShell Sampler.
