import globalsub, unittest

class MyTest( unittest.TestCase ):
     def setUp( self ):
         globalsub.subs( shutil.copytree )
     def tearDown( self ):
         globalsub.restore( shutil.copytree )

You can also pass a function to subs like so:

     def setUp( self ):
         self.copied_trees = []
         def fake_copytree( src, dest ):
             assert os.path.exists( src )
             self.copied_trees.append( (src, dest ))
             return dest # or whatever the thing should return
         globalsub.subs( shutil.copytree, fake_copytree )

$ pip install globalsub

HTH,
Mike
