Question

Is it possible to rename method in Python?
Something like this

class Validation(unittest.TestCase):

    def __init__(self, methodName='runTest'):
        super(Validation, self).__init__(methodName)
        #Doesn't work
        setattr(self,'do_folders_equal','test_do_folders_equal')

Rename method ‘do_folders_equal’ to ‘test_do_folders_equal’..
Usage above , obviously, is incorrect…How to do this hack?

Answer 1

You wouldn’t rename it, you’d just assign it to another variable:


class Validation(unittest.TestCase):

def __init__(self, methodName='runTest'):
    super(Validation, self).__init__(methodName)
    self.test_do_folders_equal = self.do_folders_equal

However there can sometimes be some weird interplay with inherited methods etc, so it sort of depends what you are trying to do. Not sure how this behaves on old-style classes either…

EDIT: Or using a name read at runtime:


class Validation(unittest.TestCase):

def __init__(self, methodName='runTest'):
    super(Validation, self).__init__(methodName)
    setattr(self, 'test_do_folders_equal', getattr(self, 'do_folders_equal'))
