Error while running test case

I need to test my code below. I am using one test to see if it is working or not. but dont know what exactly I should pass as a parameter in the test code. Please see the test code at the end and please guide me what value I should pass here? Because whatever I write here, it throws me an error.

The Error is:-

ERROR: testOne (__main__.IsOddTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "binary_light.py", line 67, in testOne
    self.failUnless(_create_device('urn:schemas=upnp-org:device:BinaryLight:1'))
NameError: global name '_create_device' is not defined

----------------------------------------------------------------------

In your testOne() method, you're calling _create_device(), which isn't a global function it's a method on SwitchPower objects.

You probably want to create a new SwitchPower object.

_create_device() is not defined in class IsOddTests. It is defined in BinaryLight.

I'm not completely sure about this, but what about changing:

self.failUnless(_create_device('urn:schemas=upnp-org:device:BinaryLight:1'))

to:

bl = BinaryLight()
self.failUnless(bl._create_device())

I removed:

'urn:schemas=upnp-org:device:BinaryLight:1'

because it was in the definition of _create_device().
