I have a JMeter script where I should access a .xls file with multiple tabs and alter values .
The .xls file has values like , RASD1234,TWER1234,ZAST1234 . I should change the numeric value to unique values each iteration like RASD1235,TWER1235,ZAST1235 in all tabs . How can I achieve this in JMeter
Download tika-app.jar and put it into JMeter Classpath
Restart JMeter to pick the .jar up
Once you do this you will be able to use POI-HSSF API to edit the Excel file
Just one piece of advice: since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language for scripting so consider doing this in Groovy (normal Java syntax will also work)

I have started leaning JMeter. So, this one tutorial asked to save the Bean Shell Assertion. On trying to save it, I am getting Access Denied error.
Your user has not right to write in this folder.
Change to your user's Documents folder
In order to be able to save file under the Program Files folder you need to be an Administrator of your machine.
Another option is running JMeter as an Administrator:
Or alternatively you can grant to your user account Full control rights onto JMeter folder:
In general overall quality of the guide can be a big question mark as:
Assertion will not be executed if there is no Sampler
Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting as:
Groovy scripts can be compiled and cached - it greatly improves script performance
Groovy engine is faster than Beanshell per se
Groovy is more "modern" language and it supports all underlying Java features while in Beanshell you're stuck at Java 5 language level and cannot use generics, streams, lambdas, etc.
On top of this Groovy has a lot of enhancements, for instance built-in JSON support
If above points are enough to convince you - check out Scripting JMeter Assertions in Groovy - A Tutorial article.
I have a Beanshell Listener which has a certain code written to fetch some metrics during the execution of the script. I want this listener to be appended to every other new Jmeter script automatically when a user creates a script in Jmeter. Is this possible?
Example:
A user opens a new Jmeter script and by default, the Beanshell listener created earlier having the code should automatically be there in the script for the thread group rather than adding a new Beanshell listener and copy-pasting the code to this newly appended listener. Is this scenario possible? TIA.
Jmeter Version - 4.0
You can take a look into JMeter Templates and come up with your own Template having whatever Test Elements you want and encourage colleagues to use your template for creating the tests.
Be aware that starting from JMeter 3.1 it is strongly recommended to switch to JSR223 Test Elements and Groovy language so it is a good time to consider migration.
You don't need to copy paste code, Just put the file name which contains the script in file name field (can use Browse)
Script file A file containing the BeanShell script to run. The file name is stored in the script variable FileName
Notice that you better move to JSR223 Listener according to JMeter's best practice:
Since JMeter 3.1, we advise switching from BeanShell to JSR223 Test Elements
What I try to achieve is to get JMeter results in 2 formats, for the same test execution. CSV is the one I'm mostly interested in, unless there are failures - then I may need to use data which can be saved only to XML. I can't use XML for most occasions, due to misc reasons.
I was looking at jmeter.save.saveservice.output_format cfg entry, it doesn't seem to accept both as valid entry. I was also looking at JMeter code itself, it also clearly separates both options.
Did anyone invent a hack to get both JMeter outputs at the same time?
Solution for both standalone JMeter and jmeter-maven-plugin is welcome.
If you use JMeter Maven plugin, as per Five Ways To Launch a JMeter Test without Using the JMeter GUI guide the default output has to be XML.
If you need CSV output as well - just add Simple Data Writer listener. If you looking for CSV data to be in line with JMeter default CSV values configure it as follows:
I'm looking for an option to read a non-CSV file using one of the JMeter functions. The file i'm using has extension of .csr. This file has a binary array format which would be converted to json format using a Java code. Jmeter has to pass the data from this file to the Java class.
The easiest way is using __FileToString() function to read the file into a JMeter Variable for reusing where required.
Another option is: given jar file(s) which can decode that .csr binary file into JSON are in JMeter CLASSPATH you can do it directly in JMeter using JSR223 Sampler which allows executing arbitrary code in variety of supported languages (groovy is recommended for maximum performance)
Is there a way to create a JMeter test plan without going through the GUI?
I.E. can you create a script with pure code?
In a way - yes. You can create the JMX file in a text editor, but it would require knowing what every component needs.
You're better off creating in GUI mode and modifying the JMX file manually as needed.
Yes it's possible to write a test plan just by writing JAVA code.
The key classes to look into are:
StandardJMeterEngine - the main class which configures the Test Plan and executes it
HashTree - a special collection which holds Test Plan elements
A minimum of JMeter Controllers necessary to run the test.

I can write and run JMeter without GUI. JMeter use JMX file, as you can here.
Not entirely sure why you would want to write a JMX in this way? ... But yes, entirely possible if you understand the structure of the document.
You could use any basic text editor to achieve this (notepad / notepad++ for example).
A JMX file is a saved JMeter project in XML format. ~ Ref
Depending on your needs you could the browser editor from the JMeter Plugins website.
jmeter-plugins.org/editor/
Or simply save a basic JMX as a template and spend loads of time learning the structure, syntax and namings etc.
