We don't write tests separately and ahead of time for the ability to 
import a module, the validity of a ZCML change, or the absence of lint. 
 To me this is a matter of validity, not of behaviour.

A simple assertProvides will often expose small mistakes in interface 
declarations.  Our code takes no notice of incorrect parameter lists in 
interfaces, or functions that have been specified but never used or 
implemented, but they do cause friction for developers.
