I'm an absolute rookie here (JAVA i mean), spent hours looking for a solution, now i just want to shoot myself.
I want to create a string in the beanshell assertion which is placed right above the HTTP Request.

  • In the beanshell i wrote:

    String docid="abcd";

    (in actuality i wish to concatenate a string with some variables)

  • In HTTP Request, send parameters i add ${docid}.

In BeanShell Assertion description section you can find the following:

 vars -  JMeterVariables  - e.g. vars.get("VAR1"); vars.put("VAR2","value"); vars.putObject("OBJ1",new Object()); 
 props - JMeterProperties (class java.util.Properties) - e.g. props.get("START.HMS"); props.put("PROP1","1234");

So to set jmeter variable in beanshell code (BeanShell Assertion sampler in your case) use the following:

String docid = "abcd";
vars.put("docid",docid);

or simply

vars.put("docid","abcd");

and then you can refer it as ${docid}, as you've done in your HTTP Request.

  • Thank you so very much for your help!! If i'm not asking too much how will i be able to concatenate a variable in the beanshell assertion only. my objective is actually to run a loop and keep concatenating the string. I was planning to run this sampler in a loop controller and concatenate the variable to itself with little modifications with each loop run – Suyash Jul 27 '12 at 07:32
  • Ignore the above comment, i managed to do concatenation and also looping, but somehow i am not able to pass the value from one beanshell sampler to another. i tried the vars.get("varname") but its not working. it only works for http request type variables. – Suyash Jul 27 '12 at 08:34
  • Hm. Try use [Debug Sampler](http://jmeter.apache.org/usermanual/component_reference.html#Debug_Sampler) at least to track problem variable between beanshell samplers. As well you can also use props.get/.put in the same manner - maybe this will work better. – Aliaksandr Belik Jul 27 '12 at 14:07

If you don't know Java well, you can use any of BSF or JSR223 Test elements and then select Javascript language as scripting language

If you need to pass value from one bean shell sampler to another, you should use variables.

vars.put("a", "something")

In other sampler, you should have something like:

String otherSampler = vars.get("a")

About debugging Shell Samplers - It is not so easy. I suggest to use SampleResult object. How to use it, you can see here Debugging Bean Shell Sampler
