Absolutely not.  This is an issue we come across quite a bit with the  
enthought tool suite packages (now 'Projects') wherein tests are not  
really 'unit' tests (they are integration or functional test) and  
introduce a dependency in order to test integration with another lib  
or a particular interface function.  There are various approaches to  
solve this (different test levels comes to mind, the decorator  
approach to performance tests seen on this list as well).  The default  
test level certainly shouldn't call this test, though.
