__init__ variable not found in test class?

I recently changed from using nose to nose2, however a lot of my testing code seems to have broken in the process. One thing in particular is the init variable i put in my test class "self.mir_axis" is giving this error:

mirror_index = mirror_matrix.index(self.mir_axis)
AttributeError: 'TestConvert' object has no attribute 'mir_axis'

This used to work with nose, however with nose2 my init variable for some reason is no longer registering. Am I missing something here? Im using python 2.7.3, and eclipse as an IDE btw.

from nose2.compat import unittest
from nose2.tools import params
from nose2 import session
from nose2.events import ReportTestEvent
from nose2.plugins import testid
from nose2.tests._common import (FakeStartTestEvent, FakeLoadFromNameEvent,
                                 FakeLoadFromNamesEvent, TestCase)#
# Import maya modules
import maya.cmds as mc
# Absolute imports of other modules
from neo_autorig.scripts.basic import name
from neo_autorig.scripts.basic import utils

# Test class for converting strings
class TestConvert(TestCase):
    counter = 0 # counter to cycle through mir_axes

    def _init__(self):
        mir_axes = ['xy', '-xy', 'yz', '-yz'] # different axes to be applied
        self.mir_axis = mir_axes[self.__class__.counter]
        self.__class__.counter += 1 # increase counter when run
        if self.__class__.counter > 3:
            self.__class__.counter = 0 # if counter reaches max, reset
        self.utils = utils.Utils(self.mir_axis, False) # pass module variables

    def setUp(self): # set up maya scene
        side_indicator_l = mc.spaceLocator(n='side_indicator_left')[0]
        side_indicator_r = mc.spaceLocator(n='side_indicator_right')[0]
        mirror_matrix = ['xy', '-xy', 'yz', '-yz']
        trans_matrix = ['tz', 'tz', 'tx', 'tx']
        side_matrix = [1, -1, 1, -1]
        mirror_index = mirror_matrix.index(self.mir_axis)
        mc.setAttr(side_indicator_l+'.'+trans_matrix[mirror_index], side_matrix[mirror_index])
        mc.setAttr(side_indicator_r+'.'+trans_matrix[mirror_index], side_matrix[mirror_index]*-1)

    def tearDown(self): # delete everything after
        mc.delete('side_indicator_left', 'side_indicator_right')

     def test_prefix_name_side_type(self): # test string
            nc = name.Name('prefix_name_side_type')
            existing = nc.get_scenenames('transform')
            self.assertEqual(nc.convert('test', 'empty', self.utils.find_side('side_indicator_left'),
                'object', existing), 'test_empty_l_object')
            self.assertEqual(nc.convert('test', 'empty', self.utils.find_side('side_indicator_right'),
                'object', existing), 'test_empty_r_object')

# run if script is run from inside module
if __name__ == '__main__':
    import nose2
    nose2.main()

I see two problems with the snippet you posted:

The first one is def _init__(self): is missing an underscore; it should be def __init__(self):

The second one (and seems to be the reason for the error) is the fact that the first line in _init__, mir_axes = ['xy', '-xy', ..., should be self.mir_axes = ...

Edit

You should use setUp instead of __init__ regardless, according to Ned Batchelder of Coverage.py fame. :)
