Service Virtualization

What is the process of creating virtual services using XML? Also how can i give different header responses for same request?

Hi Bala, it is probably best that you review the use of Sidecar files. Let's say that I have an R/R pair with the following file names.

someTransaction-req.txt

someTransaction-rsp.txt

Add a third file containing the response headers.

someTransaction-rsp-meta.properties

In the response meta-properties file add the headers you want, for example:

HTTP-Response-Code=404
HTTP-Response-Code-Text=Fail,Fail

Content-Type=application/json
transactionId=ab3CDE226fgh35IJ
Custom-Header-Field=MyCustomHeader

Refer to: https://communities.ca.com/message/241984144-re-how-to-implement-respone-and-request-pair-using-all-the-4-methods?commen…  for additional detail or check out docops at: Request/Response Pairs - DevTest Solutions - 10.1 - CA Technologies Documentation  

If you needed to include multiple responses for a given request each having its own set of headers:

- Check Allow Duplicate Specific Responses on the main panel in the RR Pair Recording wizard

- Create a series of RR Pair Files

someTransaction-req.txt

someTransaction-rsp1.txt

someTransaction-rsp1-meta.properties

someTransaction-rsp2.txt

someTransaction-rsp2-meta.properties

Each response meta-properties file can have different HTTP Response headers.

Bala, if you need duplicate responses, then Allow Dups and create multiple requests that are the same each having a different response. Assume the same request is in someTransaction1 and someTransaction2 but different responses and headers are needed.

someTransaction1-req.txt

someTransaction1-rsp.txt

someTransaction1-rsp-meta.properties

someTransaction2-req.txt

someTransaction2-rsp.txt

someTransaction2-rsp-meta.properties

Hi Joel,

Thanks for your reply.I tried as suggested by you.

1) Created virtual service using req,rsp and rsp-meta.properties

2) When i verified the virtual image I didnt see any response,instead I have see the values in meta.properties.

Sample response placed below

HTTP-Response-Code=500

Server=nginx/1.9.4

Date=Tue, {{=doDateDeltaFromCurrent("dd MMM yyyy","-435D");/*01 Nov 2016*/}} 22:46:42 GMT

Content-Type=application/json;charset=utf-8

Could you please suggest the way forward

Hi Bala,

You should create the virtual service using:

someTransaction-req.txt   (Request)

someTransaction-rsp.txt   (Response)

not this one:

rsp-meta.properties  , this is just for meta.

The final solution included the rsp-meta.properties file in order to set the desired response codes of HTTP 500, etc. There was a subtle file name issue in the meta.properties file.

After cleaning up filenames, the R/R Pairs were run to create a VSI which set the proper response and response codes. 

The JSON DPH was included automatically, and we added the REST DPH manually.

This enabled us to build a proper VSI with proper responses. 

Hi Joel,

Could you please let me know the details in steps to avoid the "Transfer-Encoding: chunked" issue.

Do I need to create virtual service with out using meta-properties file?

Thanks,

I believe you should open a Support Ticket on this one.

When I send a response to Postman and SoapUI, I can see in the logs that the message is placed on the wire, but as you state, I do not see a response in the client.

Error sending HTTP request.

You might turn on DEBUG mode in the logging.properties file to see if some other malfunction is occurring. When chunked is used, I believe the last segment sent should contain a content-length of 0 bytes and no data. I cannot see if that is happening in this situation.
