Hello Henrik,
Yes, exactly.
As an example, we are using soapUI Pro for mocking a lot of webservices and there is a need to reply with dynamic responses. The data for these responses may come from a database, a text file, an XML structure, etc. In the current version I manually scripted the database access to retrieve the test data based on certain input values in the request message. However it would be a lot easier and less error-prone doing this with some kind of "MockStep".
What I'm thinking of is an analog to the "TestSteps", e.g. inserting delays, defining data sources, loops, etc. I'm just brainstorming...
Sincerely,
Robert
