In the Task Coach (http://www.taskcoach.org) test suite we sometimes
need to skip tests on certain platforms. We use two simple decorators
for that:

def ignore(*args, **kwargs):

def runTest(func):
   return func

def onlyOnPlatform(*platforms):
   ''' Decorator for unit tests that only run on specific platforms. '''
   return runTest if wx.Platform in platforms else ignore

def skipOnPlatform(*platforms):
   ''' Decorator for unit tests that are to be skipped on specific
       platforms. '''
   return ignore if wx.Platform in platforms else runTest

These are used like this:

   @test.skipOnPlatform('__WXMSW__') # GetItemBackgroundColour
doesn't work on Windows
   def testEffortColor(self): # pragma: no cover
       self.assertEqual(wx.RED, self.viewer.widget.GetItemBackgroundColour(0))

Cheers, Frank
