Yes that is a variant, but if someone misspells it? “N/S” for exampel?
Another workaround is to have a Boolean Asset as a flag if I want to use the TestConfiguration, and then I can just check if flag is true or false in code.
But since an Asset is a String it should be possible to set it to empty since that is a default value in VB.Net and C#.
(Edit: A default string in VB.Net is Nothing and in C# it is null.)
