Why data modifiers is not modifing parameters in reqest

I'm new to LoadComplete. I'm fighting with load test preparation and I've stuck with data modifiers. I read the documentation and tried figure it out but I need someone to help me to show where I'm making mistake.

 

I have request-response-request chain:

 

Reponse:

<?xml version="1.0" encoding="UTF-8"?>
<serviceResponse returnLength="2">
<output name="mainCaseId"><variable type="String"><![CDATA[76209]]></variable> </output>
<output name="error"><variable /> </output>
</serviceResponse>

 

I did a correlation in Parameters tab and assigned value 76209 to a variable vMainCaseId.

 

Now I want to populate value 76209 into succeeding request (below)

Request:

GET /portal/jsp/callService.do?serviceRef=1.dcc8b725-7894-44c7-af42-a61875970bf3&snapshotId=2064.e66d1293-fdd9-438c-bea1-784d9f58f778&input=%3Cinput%20name=%22elementValue%22%3E%3Cvariable%20name=%22mainCaseId%22%3E99999%3C/variable%3E%3C/input%3E HTTP/1.1

 

I need to put 76209 instead of 99999 (highlighted)

 

I tried Data Modifiers tab:

%3E(\d{3,})%3C --> vMainCaseId

mainCaseId%22%3E\K(\d{3,}) --> vMainCaseId

 

and few more but no luck. 

 

How should it be done corectly?

 

How can I debug what and see what values are actualy catched into variables?

 

Thanks in advance for any hints.

      Hi Ryan,

       

      Thanks for feedback.

      I did try both methods you offer and put variable into the request but no luck at all.

       

      Documentation about parametrisation of URLs says that:

       "Variables followed by characters other than the separators /, ? and &. Semicolons (;) are not separators"

      and the problem here is that the value I want to replace is not followed by any of above separators.

       

      GET /portal/jsp/callService.do?serviceRef=1.dcc8b725-7894-44c7-af42-a61875970bf3&snapshotId=2064.e66d1293-fdd9-438c-bea1-784d9f58f778&input=%3Cinput%20name=%22elementValue%22%3E%3Cvariable%20name=%22mainCaseId%22%3E99999%3C/variable%3E%3C/input%3E HTTP/1.1

       

       

       

      Any clue?

       

      Thanks,

      Olaf

    Hi Olaf,

     

    First (this will be referenced below), decoded value for the request is:

    GET /portal/jsp/callService.do?serviceRef=1.dcc8b725-7894-44c7-af42-a61875970bf3&snapshotId=2064.e66d1293-fdd9-438c-bea1-784d9f58f778&input=<input name="elementValue"><variable name="mainCaseId">99999</variable></input> HTTP/1.1

     

     

    I would try the following:

    -- It is my guess that you are using Data Selector to get the value of mainCaseId into the vMainCaseId variable;

    -- Assume, that the regexp for this Data Selector is '<!\[CDATA\[(\d{3,})\]\]>';

    -- Now, try to put something like this into the Subexpression field for this DataSelector:

    <input name="elementValue"><variable name="mainCaseId">$1</variable></input>

    I.e., you will assign to the vMainCaseId variable not just case id, but the whole value of the 'input' URL parameter;

    -- And finally, assign the following for the subsequent request:

    GET /portal/jsp/callService.do?serviceRef=1.dcc8b725-7894-44c7-af42-a61875970bf3&snapshotId=2064.e66d1293-fdd9-438c-bea1-784d9f58f778&input=@vMainCaseId HTTP/1.1

     

    Does this work?
