I am not sure what you mean by "on their own".  Do you expect side 
effects from test executions?  From what I understand a TestCase should 
ideally be independent and probably also side effect free.  Then you 
could easily lump them into a single TestSuite.  The only issue I can 
think of off the top of my head would be class instance variables and 
required files which might yield different results - but then again, 
relying on a specific require order is probably not a good idea in its own.

Kind regards
