The classes SingleModMPProjectTestCommon and SingleModNLTRestProjectTestCommon define a large number of abstract methods which are actually just getters. This means all the classes that extend these base classes must implement the methods in exactly the same way. It would be simpler if the base classes simply implemented the getters one time and the derived classes used them.

This requires the base classes to define local variables and to implement setters as well as getters but this is quite simple to do and hence worthwhile to allow this refactoring to go forward.
