title: How can I define one setup function for all nosetests tests?
body: <p>I'm using google app engine with python and want to run some tests using nosetest.
  I want each test to run the same setup function. I have already a lot of tests, so I don't want to go through them all and copy&amp;paste the same function. can I define somewhere one setup function and each test would run it first? </p>
  
  <p>thanks.</p>
