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
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..?

Re: Place holder for function execution / Variables evaluation
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?

Re: Place holder for function execution / Variables evaluation
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. -- Andrey Pokhilko 11.11.2018 20:53, Philippe Mouawad пишет: > 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 >
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
