Help needed with unittest and global

[Ian Hobson]

Hi all,

I am trying to develop  a PyQt application, and I want to unittest it.

After three false starts, I am plainly unaware of something rather basic 
- can some kind person please help me out?

This is a log to show what I have so far
D:\work\ian>type testAll.py
# coding=utf8
#   testAll.py - run all tests.
import unittest
import sys
from PyQt4.QtGui import *
from testCubic import testCubic
global app
def main():
     suite = unittest.TestLoader()
     suite.loadTestsFromTestCase(testCubic)
     unittest.TextTestRunner().run(suite)
if __name__=="__main__":
     global app
     app = QApplication(sys.argv) # set gloabl app
     unittest.main()

D:\work\ian>type testCubic.py
# coding=utf8
#    testCubic.py - tests the top level module
import unittest
global app
class testCubic(unittest.TestCase):
     def test001_walkingSkeleton(self):
         global app    # use global version
         app.processEvents() # fails
D:\work\ian>python testAll.py
