Hi guys!
My student asked my why his unit tests don't work as they should, and I just could answer him. Here is the simplified case.
There is a class with a required unique property Name:
InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.
