Deletion of Unittest

Comment: to XUnitList of unit testing frameworks. Sure, there may be books giving tutorials on how to use the module, but I don't see it receiving any mainstream media coverage. Virtually nothing can be written on this topic beyond how to use it, and per |NOTHOWTO, even that would be out of place here
