title: unittest setUpClass alternative for python < 2.7
body: <p>In Python 2.7, it is possible to run class level setup in unittest.Testcase as follows:</p>
  
  <pre><code>class ClassName(unittest.TestCase):
      @classmethod
      def setUpClass(self):
          print 'Some class level setup'
  </code></pre>
  
  <p>Unfortunately, I need to run some tests in Python 2.6 environment. What is the alternative for setUpClass in that version?</p>
