HOW TO Transfering data between Thread?
Hi All.
I have a task, what I don't know solution - I need generate a variable with
a value and then use this variable in user parameters pre-processor. I am
using BeenShell sampler for generation data and jmeter context variables to
set it in.
Because user parameters preprocessor is running before any sampler, my
approach doesn't work.
I have tried to create two thread groups in test plan - one for generating
data, and the second is actually the test. I am unable to transfer data via
context between the thread groups.
If somebody knows how to do it - please let me know.
I have tried to create two thread groups under a "main" thread groups. I was
able to use the same context for the transferring generated data but these
two thread groups were running twice even the settings were set for all of
them to run once.
I will really appreciate any ideas and advices.
Thank you, very much.
Pavel

Hello again.
I am still looking for posibility to transfer data between thread groups
using API.
Does anybody have idea how to do it using api?
Does anybody know, how to make a sampler be executed before a pre-processor?
Thank you.

Re: HOW TO Transfering data between Thread?

I tried the scenario you have described:
=====================
The pre-processor can be added as a child of a sampler, e.g.
- Sampler 1
- Sampler 2
- - Pre-Processor
This will force it to run after Sampler 1 and before Sampler 2.
======================
In my case, "Sampler 2" is Bean Shell script that makes the following call
on a context variablel:
vars.put("unique_word",uniqueWord);
User Parameter pre-processor is a child of that bean shell script. The
pre-processor is trying to set
account = ${unique_string}
Is there any solutions or advises to that problem?

This is because the variable "unique_string" does not exist at that point.

As well, how to read/write from a bean shell script:
a) property
b) user defined variables
in run time.
Can you give an example if it is possible?

If pre-processor is a child of a bean shell sampler, the pre-processor is
called first any way.
Here is my scenario:
- BeanShell sampler sets variabel unique_string = qwerty
--- child pre - processor sets the variable account = ${unique_string}
the account gets value "${unique_string}" but I am expecint the value to be
"qwerty"
Please help.

The pre-processor can be added as a child of a sampler, e.g.
- Sampler 1
- Sampler 2
- - Pre-Processor
This will force it to run after Sampler 1 and before Sampler 2.
Or you can put:
Simple Controller
- Sampler 1
Simple Controller
- Pre-Processor
- Sampler 2
What are you trying to achieve?
The CSV Data Set config element might well suit the task better.
