[PyQt] Testing a standalone dialog widget

[Jones, Bryan]

All,

Thanks for the comments, particuarly the reminder on the difficult of
combining unit tests in Python with the QTest interface. What works for me
when testing: make the QApplication instance a module-level variable. Yes,
this isn't the right way to do things for traditional application...but it
works fine when testing for me. I'd be interested to hear others' comments.

Specifically, referring to the test code:
http://johnnado.com/pyqt-qtest-example/ for docs,
https://bitbucket.org/jmcgeheeiv/pyqttestexample for the code

Change MargaritaMixerTest.py starting at line 39 to be...

# This is new
app = QApplication(sys.argv)

class MargaritaMixerTest(unittest.TestCase):
    '''Test the margarita mixer GUI'''
    def setUp(self):
        '''Create the GUI'''
        # Commented out: self.app = QApplication(sys.argv)
        self.form = MargaritaMixer.MargaritaMixer()

..the rest of the code is the same...

Bryan
