From what I've seen I would have to import extra JAR files into SoapUI for this to work. The issue isn't other testers local to me running the project. The problem is there may be people using my tests that I would not necessarily have direct contact with if they run into issues.
I am trying to keep this as simple and small as possible. The projects I make need to be as stand-alone as possible, as not everyone will have the capability to add outside/3rd party jar files to SoapUI.
I am facing what may be a lot of unique constraints.
