Trying to execute few xtext based model unit tests, but getting an error which says below :

PS: However I have imported the external package :
import org.eclipse.xtext.testing.XtextRunner;
import org.eclipse.xtext.testing.util.ParseHelper;

I checked few online searches and it says, the class has to be added to CLASSPATH, then my question is how to add a package into CLASSPATH?

Hoping for a quick reply!

It's similar to Yang-Sprotty project.

It's something under xtext.myGrammar.diagram.

To be more precise, please let me know if I need to share the project explorer screenshot somewhere on email because I am not able to see any link for that on this form.
