You don't have constructor for unittest class. Because of the way
unittest framework works, (namely creates testobjects for its
purposes), creating an object is not recommended. I have not seen any
code doing it. For what you are trying to do, you could do something
like this:

(Follow along and modify as per your requirement)

import unittest

x = 100

class XMLSupport(unittest.TestCase):

    def setUp(self):
        print 'In setup'
        self.x = 3
    def test_3(self):
        self.x += 1
        global x
        x += 1

    def test_4(self):

if __name__ == '__main__':
