Testing tools for OData services

Hi all,

I managed to get my oData services up and running on my local/Cloud HANA server, using Olingo libraries and JPA.

Now I'd like to test my services. I can test the queries from the browser and from multiple clients found on the web.

However PUT/POST requests require to type in manually the body, and this is really time-consuming.

As a consequence, I'm looking for any tool which could generate POST/PUT request body for oData (much like XMLSpy/soapUI does for SOAP)

There is no SAP NW Gateway in my landscape so it is not an option, I'd like a desktop tool or browser plugin

Does anyone know whether such a tool exists?

Thanks, Regards

Vincenzo
