Hub asset testing from the IDE
Create an OL Integration module and asset from the open COBOL program, and run JSON test cases against it in the Code Viewer.
A change to a COBOL program is hard to trust until you can call it the way an API will. OL Code registers the open program as an OL Integration asset and runs JSON test cases against it in the same editor, so the loop from a code change to a verified call stays in one place.
