Hi, thank you for you answer.
My use case is: I have a lot of REST APIs (17, in development) to test in SoapUI. There are hundreds of methods.
There are unitary projects and test cases for each API. Then I have to create a project common to multiples API to do some tests on chaining API calls from differents API.
I want to develop mainly in each individual API project then copy/paste the interfaces into the common APIs test project and do as few modifications as possible.
That is the reason why I wanted to copy and paste some API configurations (and so their IDs) into new project(s).
No test case from unitary projects will be imported and new test cases would be developed in the common APIs project.
Does this implementation seems problematic to you ?
And please excuse me, I am no expert of the type of documentation you linked me to and it looks a bit cryptic to me, even though I can ask colleagues to help me if the right way of implementing this solution is to use some methods of the SoapUI API.
