You effectively can't step through all the tests (with a single  
pdb).  You can step through a single line in the test well.  While it  
sounds limiting, that has proved quite sufficient for me in  
practice.  YMMV, of course.

Yup, that won't work.  You need to put the pdb on the same line as  
the thing you want to trace, i.e.

>>>> import pdb;pdb.set_trace(); gsm =  
>>>> zope.component.getGlobalSiteManager()

>>>> gsm.provideUtility(I11, ob11)

That would let you trace the getGlobalSiteManager call.  If you  
wanted to trace the provideUtility calls then you would want to put a  
pdb in there too.  I don't think I've ever had more than one in at a  
time, though.
