I would like to create a TestCase to make request to a VS created thanks to RRpairs and copybooks. Rather than creating a bunch of fixed length messages, I would like to generate those based on a .xls file that contains all data, and a request.cpy file to build the request. It is possible to do a similar thing with WSDL but there is no specific step to do that in the DevTest Workstation. Is there any custom way to do so?
