Hi Ali,
yes, it is actually possible to create your own teststeps in soapUI, but it ain't as straight forward as it is in loadUI. You'll have to create at least two classes; one being a WsdlTestStepFactory and one being a WsdlTestStep, the first needs to be registered with the WsdlTestStepRegistry when soapUI starts (since there is no hook for this happening yet you can add it from the project OnLoad event instead) and the seconds is the actual teststep that needs to run, etc. Then there is quite a lot of plumbing required to get right-button menus, editor windows, etc in place. Can you elaborate on the scope of your components so I can prepare an example?
regards!
