Hello

i am using Random HandleBar in .Net to receieve a randome response from a list of predefied values using wiremock.

String List: "{{Random Type=\"StringList\" Values=[\"a\", \"b\", \"c\"]}}"
in my case a, b or c are different json responces. as following :

a => {'result':'ERROR','description':'Value Not Found','ReqCode':'123'}
b => {'result':'ERROR','description':'Value set to Null','ReqCode':'456'}
c => {'result':'ERROR','description':'More than one item','ReqCode':'789'}

what i need to have in my project , is to understand which response ( a , b or c ) is associated with what request ( but i don't want the ReqCode to be fixed and pre-defiend).

we already know that one way to pass a dynamic value from request into response would be using "Response Templating - {{ }}" . but in this case , i could not find a way to pass this dynamic value using Random responce handlebar as the following :

"a\ => "{'result':'ERROR','description':'Value Not Found','ReqCode':'{{ my random Code }}'}
"b\ => "{'result':'ERROR','description':'Value set to Null','ReqCode':'{{my random Code }}'}
"c\ => "{'result':'ERROR','description':'More than one item','ReqCode':'{{my random Code }}'}

using this what i receive in response is the string itself ({{my random Code }}) rather than the value i passed in request body.
Is there any way to do this in wiremock ?

Thanks

So depending on a random value from a string list, you want to return a different message and a random code?

Hello .

I need to pass a value into the Random string list.
as an example

String List: "{{Random Type=\"StringList\" 
Values=[\"{'result':'ERROR','description':'Value Not Found','ReqCode':'{{ my random Code }}'}\",
              \"{'result':'ERROR','description':'Value set to Null','ReqCode':'{{my random Code }}'}\",
              \"{'result':'ERROR','description':'More than one item','ReqCode':'{{my random Code }}'}\"
]}}"

so my request body would be (using a Post request) :

 {
    'ReqCode':'1234'
 }

and the response would be a random string, chosed from the Random List filed with the passed data.
so the response body comming from wiremock server would be:

{'result':'ERROR','description':'Value set to Null','ReqCode':'1234'}
How am i able to implement this ?
Thanks
