def mypymethod(param1)   myresult = os.path.something   return myresult 

and wish test mypymethod wish os.path @ case return "yourmockresult" when call test method

you should use michael foord's mock module same.

from documentation:

>>> mock import mock >>> real = productionclass() >>> real.method = mock(return_value=3) >>> real.method(3, 4, 5, key='value') 3 >>> real.method.assert_called_with(3, 4, 5, key='value')
