Help With Passing Multiple Variables From a Regular Expression
Extractor
I am having difficulty understanding how to pull multiple values from a Regular Expression Extractor and pass them along in my script.
Basically, here's what I'm trying to accomplish:
1. Submit a form which will return 0 or more links to other pages. Each link has four parameters which I need to pull out for later processing.
2. Randomly select one of the links.
3. Put the four parameters into four variables for use by another Controller.
Here's what I tried (which doesn't seem to work):
* HTTP Request
o Regular Expression Extractor-Var (all of the Var on the page will be the same value)
o Random Variable from 1 to ${Var_matchNr} called Sample
o Regular Expression Extractor with Match No. set to ${Sample} for each of the other parameters.
When I run this with a Debug Sampler, Sample is not getting set to anything.
Is there a way to just set a variable to a value during processing? Is there a better way to do what I'm doing?
Thanks,

You can create variables using
http://jakarta.apache.org/jmeter/usermanual/component_reference.html#User_Parameters
Name: User_1:
A ${Var_1_g1}
etc.
If you want to change the _1_ part of the Regex var, you will need to
use the function
http://jakarta.apache.org/jmeter/usermanual/functions.html#__V
i.e.
A ${__V(Var_${N}_g1)}
where N=1

hi
ok , if you know java bean shell is easy and invaluable (though maybe

Thanks, Deepak.
I'm not familiar with BeanShell, but I was able to use what you sent to get the desired result.
What I ended up doing was randomly select one of the links and then use your script to parse out the parts I need for my other module.

You should be able to get these values using the functions (i.e. you dont
need to explicitly define A) __V, __Random. (No time to test :) )
Fairly easy to do this in BSH
vars.put("A", vars.get("Var_" + random + "_g1"));

RE: Help With Passing Multiple Variables From a Regular Expression
Extractor
Posted by Steve Eckhart <St...@wausaufs.com>.
I can't use Match No = 0 because I could get a different link for each of the three Regular Expression Extractors. I need each part from the same link.
This would be fairly simple if I understood how to assign a variable directly. For example, suppose I have:
Var_1_g=3
Var_1_g0=href="pagerequest.aspx?a=7000&b=104&c=12047
Var_1_g1=7000
Var_1_g2=104
Var_1_g3=12047
What I would like to end up with is three output variables:
A = Var_1_g1 = 7000
B = Var_1_g2 = 104
C = Var_1_g3 = 12047
I can't figure out from the documentation how to set the value of a variable outside of a Regular Expression Extractor or a Random Variable.

Re: Help With Passing Multiple Variables From a Regular Expression
Extractor
Posted by Deepak Shetty <sh...@gmail.com>.
Hi
You'd probably need to check the scoping rules for Random variable config
element. I think you've created everything as children of the HTTP request
right?
Depending on how easy difficult it is to extract the values i would try
Option 1
a. Each Parameter is extracted separately (so in your case you would have 4
Regex extractors , 1 per parameter)
b. Use __Random and __V to randomise the index and pick out the value
http://jakarta.apache.org/jmeter/usermanual/functions.html (I think this is
what you were trying)
Option 2
If its easier to extract all parameters for 1 type (e.g. they are the query
string of some url). In this case you only have 1 Regex (each result has all
parameters and you have multiple results that you want to randomise) , Use a
beanshell script or function to parse the parameters out and set them into
variables, and use random again...

RE: Help With a Null Variable
Posted by Steve Eckhart <St...@wausaufs.com>.
Deepak,
The following works:
if(vars.get("BatchLink_g3") == null)
{
vars.put("loopBatch","0");
}
else
{
vars.put("loopBatch", vars.get("BatchLink_g3"));
}
Thanks for your help!
Steve

hi
that wont work both values get replaced . What i meant was that since your
variable might be a number or a sting (the literal string ${loopBatch} , you
need to use it as a string everywhere
Something like this
//first condition is check not null
("${loopBatch}".indexOf("$") != -1) && (rest of condition like parse and
check the value)
I vaguely remember another way to do this , but ill need to go through some
of my notes and check.

RE: Help With a Null Variable
Posted by Steve Eckhart <St...@wausaufs.com>.
Deepak,
I tried setting the If Controller to
${loopBatch} != "${loopBatch}"
and checking the Interpret Condition as Variable Expression? checkbox.
I no longer get the error when loopBatch is null. However, when loopBatch=132, I would expect the condition to evaluate to true and execute the steps in the If. Unfortunately, it didn't and continued with the steps after the if.
What am I missing?

you could do this at the beanshell level
//check the number of brackets , this is pseudo code, also check that
loopBatch always has a value that is the string //representation of an
integer or an integer
if(vars.get("BatchLink_g3")) == null ||
"".equals(vars.get("BatchLink_g3")).trim())){
vars.put("loopBatch","0");
} else {
vars.put("loopBatch", vars.get("BatchLink_g3"));
}
OR
You could do it as a javascript funtion (null means the value remains as
${loopBatch} and you'd have to pass it as a string so there be quotes around
the ${loopBatch}

Help With a Null Variable
Posted by Steve Eckhart <St...@wausaufs.com>.
I have a Regular Expression which is reading a variable from a web page. I need to test this value to see if I should perform the next step or perform another search.
Currently, I have the following in a BeanShell PostProcessor to set the value of the variable:
vars.put("loopBatch", vars.get("BatchLink_g3"));
If my search returned no results, a Debut PostProcessor will report loopBatch=null. Then, the If Controller ${loopBatch} > 0 generates an error:
ERROR - jmeter.control.IfController: missing ) after argument list (<cmd>#1)
How can I test using a variable which might be null? I found a method of the Class Abstract Property getIntValue() which would give me what I want (0 when the value is null), but I don't understand how to use getIntValue() in a JMeter script.
Is this the right way to proceed? Am I missing something? I don't know much about the BeanShell command.
Thank you for any help.
