Hello,

I have a number of conceptually separate tests that nevertheless need
a common, complicated and expensive setup.

Unfortunately, unittest runs the setUp method once for each defined
test, even if they're part of the same class as in

class TwoTests(unittest.TestCase):
   def setUp(self):
       # do something very time consuming

   def testOneThing(self):


   def testADifferentThing(self):


which would call setUp twice.


Is there any way to avoid this, without packing all the unrelated
tests into one big function?


   class TwoTests(unittest.TestCase):
       setUpResult = None

       def setUp(self):
           if self.setUpResult is None:
               self.setUpResult = computeIt()

       ...

There are plenty of variations on this pattern.
