Subject Re: Sharing Variables Between Thread-Group
Date Mon, 16 Jul 2012 18:42:01 GMT
Guys, thanks for your replies.

I don't know if anyone have this experience.  I found that
${__setProperty}/${__P} pair would work between thread groups IF I use
constant value ("abc" like below example) or system variables (like
$__time(HMS). When I use a local variable ("tmp" as like in my
example) in the $__setProperty call, it doesn't work.

              tmp = "abc";
              ${__setProperty(key,tmp)};                           //
THAT DOES NOT WORK!!
              ${__setProperty(key,"abc")};
// THAT WORKS!!


I also found that it is NOT the variable value that is shared between
the thread group, it's the reference.  When I put ${__time(HMS)} in
the __setProperty call and run the test, the "key" values are
different between the two thread group.  Does anyone know how to pass
a local-defined variable value using setProperty call?


Test Plan (with 2 thread groups)

Thread-Group1 (with 1 thread)
> Dubug Sampler
> BeanShell PreProcessor
   Script:
              ${__setProperty(key,${__time(HMS)})};
       // USING TIMESTAMP
              log.info("Group 1 key = " + ${__P(key)});
        //2012/07/16 18:31:36 INFO  -
jmeter.util.BeanShellTestElement: Group 1 key = 183136


Thread-Group2 (with 2 threads)
> HTTP Sampler
> BeanShell PreProcessor
   Script:
              log.info("Group 2 key = " + ${__P(key)});
         //2012/07/16 18:31:36 INFO  -
jmeter.util.BeanShellTestElement: Group 2 key = 183119

Note that it is not the same value being logged.



Regards,
Jacky
