We published NatUnit (former NUNIT) on SourceForge today: NatUnit on SourceForge.
Due to naming conflicts with the “real” NUnit, we decided to publish it as NatUnit. However, the internal name is still NUNIT, as Natural module names are restricted to a length of 8 characters which left us with only one character to distinguish between modules, if we used NATUNIT 
NatUnit is easy to use, as the following code (a simple test case) shows. The whole framework is written in Natural itself, so you don’t have to use external tools like NaturalONE.
