Place holder for function execution / Variables evaluation
Hello,
Frequently when using JMeter functions, users don't really know for certain
use cases where to put the function, here are few examples:
- Any function which output will not be used directly by sample
parameters
- Such type of functions:
- https://jmeter-plugins.org/wiki/InterThreadCommunication/
- you want to create a variable from the output of a function and update
it on each iteration:
- User Defined Variable is not an option as evaluation occurs on
start of test
- User Parameters being a preprocessor, it would be evaluated on each
call, so you need to nest it inside a Flow Control Action, not very
intuitive right ?
I also remember when I started using JMeter that I found this part
counter-intuitive.
I think it would be nice to have a solution for this, that would evaluate
the variables/functions exactly at the place where the call is present and
without generating any SampleResult.
We could implement this:
- as an enhancement to Flow Control Action
- as a new Sampler
What's your thoughts on this ?
Regards

Of course it is possible to do it through scripting, Beanshell is not the
advised way for performances, you should use JS223 + Groovy.
The idea is to make it simple for users who don't know much coding.
So the idea of my proposal is to make it simpler for users and as a
benefit, to not generate any sample.

RE: Place holder for function execution / Variables evaluation
Posted by Paulo Maia Borges <pm...@temenos.com>.
I'm not sure I understand but I don't think I agree...
Whenever we want to change a variable in a flexible way, can't we just insert a BeanShell sampler anywhere and execute a bit of code to change a variable? Example, insert a BeanShell Sampler with this code to read an existing variable, change it, then store it somewhere else:
"""
String LoginID = vars.getObject ("LoginID");
String UserNumber = LoginID.substring (2);
vars.put ("UserNumber", UserNumber);
"""
This isn't fixed to the start of the test, nor to User Variables, nor to being a pre or post processor. The only problem I can think of is that a BeanShell Sampler generates a "sample" result, which is quite stupid when we merely want to execute some code. What we need is a new control that can just run a script without «also» generating a "sample".
Or maybe I'm just not understanding properly..?

Can you give a mock of how you envision it implemented in Flow Control

Thanks for information.
I feel this behavior should be in core.
To avoid another element, I think updating Flow Control Action is a good
candidate as it’s a sample about jmeter internals.
Thoughts?

Hi,
There's already a plugin for that:
https://jmeter-plugins.org/wiki/SetVariablesAction/
It is exactly a sampler that is used to evaluate functions/variables.
