  • 1.  Custom response with parameters

    Posted Nov 25, 2016 12:29 PM

       Hi there,


     I had some question regarding the body response for a REST call. It is written we can you {{ }} to replace parameters. For instance,

    {{= request_URLPARAMETER0}} will be replace in the response if written like that in the body response.

    My question is : how can we use conditions in {{ }} ? I couldnt figure out the syntax (on wiki they say : }} can execute arbitrary Java code and even generate realistic "everyday" data such as a valid credit card number {{=[:Credit Card:]. (Magic Strings - DevTest Solutions - 8.0.1 - CA Technologies Documentation).


    I'd like to do something like that

    <foo>{{if (request_URLPARAM == 1) { print("case1") } else { print("case2") }</foo>

    but my goal is more something like

    if (param == 1) {


    } else {



    because I have 70 possible values for my param, and in the body response i have 50 objects which are attached to one value, so I can easily say "this(these) one(s) should be sent for value XX", etc...


    Thanks in advance, I don't know if I'm clear,

    You should look at either the "Match Script" tab in the VSI file or to add a scripted dataset for the VSI Selector step in your VSM file.


    May I ask if you are able to use devtest 9.5.1? They have data-driven virtual service, Data-Driven Virtual Services - DevTest Solutions - 9.5 - CA Technologies Documentation, which may help you for the number of scenarios and variables that you have.

    If you want to modify the VSI response based on some code then you can write the code in between {{.... }} tags.


    For example:

    {{ if (param == 1) { <foo1>bar1</foo1>} else {<foo2><foo3>bar2</foo3></foo2>} }}
