copytree(src, dest) becomes:
if not PRETEND_ONLY:
     copytree(src, dest)

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
