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.

i need to write a Assertion error, assertion failure and Assertion failure message(example data below in the pic) to a csv file. What is the best way to do this? Is there a possibility to create a JSR223 Sampler to read assertion messages from all http requests at once and save that to csv file? Built-in saving to file does not meet requirements.
Picture
JSR223 Sampler will only have access to the previous sampler result, I would recommend using JSR223 Listener and the following code:
vars.put('failureMessage', prev.getAssertionResults().find { assertionResult -> assertionResult.isFailure() }.getFailureMessage())
the code will extract the failure message from the first assertion
then you need to declare Sample Variables property in user.properties file like:
sample_variables=failureMessage
and finally the variable can be written to a file using Flexible File Writer listener (this guy can be installed using JMeter Plugins Manager)
While doing Testing I need to taken the token from Oath API and use it in another subsequent API's which is successfully done. But when HTML report is generated through CLI the Oath API's Response time and Throughput is also calculated, is there a way we can ignore that request ?
Add to requests JSR223 PostProcessor below them which will ignore request/response
prev.setIgnore()
prev - (SampleResult) - gives access to the previous SampleResult
Call this method to tell JMeter to ignore this SampleResult by Listeners
There are following options:
Add JSR223 PostProcessor as a child of the Sampler(s) you need to exclude from Listeners/test results/whatever and put the following code into "Script" area:
prev.setIgnore()
Use FilterResults Tool (available via JMeter Plugins project, can be installed using JMeter Plugins Manager), it allows excluding sample results basing on strings or regular expressions or time offsets or both
JMeter .jtl result files are basically CSV files, you can use your favourite text editor or tool like MS Excel to remove the result entries you're not interested in
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 lot of files that i would like to upload to test my service but i need to pick up random files and send it. Is possible get random files and delete the file when request is completed?
Thank's in advance.
JMeter doesn't provide any test element to create random files and delete them, so you'll have to write the relevant code.
For example:
Add a Beanshell PreProcessor and Beanshell Post Processor as children of the requests which performs file upload
Put the following code into Beanshell PreProcessor "Script" area
import org.apache.commons.io.FileUtils;
File myFile = new File("myFile.txt");
FileUtils.writeStringToFile(myFile, "JMeter rocks!");
The code above creates "myFile.txt" file in JMeter's current working directory and writes "JMeter rocks!" line to it
In order to delete the file after request you can add the following code into the Beanshell PostProcessor
import org.apache.commons.io.FileUtils;
FileUtils.deleteQuietly(new File("myFile.txt"));

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.
