Nose plugin methods don't shoot

Question

I am trying to write a nose 1x plugin. I can't seem to run many methods.

For example:

import logging
import os

from nose.plugins import Plugin

logging.basicConfig(filename='example.log',level=logging.DEBUG)

class MyPlugin(Plugin):
    name = 'My Plugin'

def options(self, parser, env=os.environ):
    logging.debug("in options")    

def configure(self, options, conf):
    super(NoseSauce, self).configure(options, conf)
    if not self.enabled:
        return

def begin(self):
    logging.debug("in begin")

def finalize(self, result):
    logging.debug("in finalize")

What I get in my log file:

DEBUG:nose.plugins.manager:DefaultPluginManager load plugin config = testconfig:TestConfig
DEBUG:root:in options
DEBUG:root:in configure

So, these methods don't seem to shoot. For example, there is no log for finalize (). When I look at the .tools.base nose, I see that there are only a few members in the Plugin class, but the "IPluginInterface" has all the methods defined, but keywords are passed instead of keywords. I don’t understand all this. I thought that Python has no interfaces, and even if it is, I do not see this interface being used anywhere.
