As you may remember, when we describe how to create data services and expose them as REST services, we use SOAPUI to test them since we need to add a property to the request header. You cannot perform this customization using the built-in tester, so we use the SOAPUI tool, which allows you to do this kind of modification and any others you may need.
SOAPUI is an open source testing tool for SOAP and REST services that enables you to build any kind of request. As they say on their website, it is The Most Advanced REST and SOAP Testing Tool in the World, and there is a free open source version and a professional one. We will work with the free SOAPUI open source version.
This tool allows you to not only create fully customized requests to test a service, but also gives you many other features that are quite useful on a daily basis in a professional environment...
