It also sets the attributes to the default values inside the tests,
taking them from the interface definition instead of the class definition..
class MyObject:
implements(IMyObject)
what = 42
vs.
class IMyObject(Interface):
what = Int(title=u"Whatever",default=42)
class MyObject:
"""
>>> from zope.interface.verify import verifyClass
>>> verifyClass(IMyObject, MyObject)
True
Try changing the attributes:
>>> obj = MyObject()
>>> obj.what
42
>>> obj.what=56
>>> obj.what
56
"""
implements(IMyObject)
what = FieldProperty(IMyObject['what'])
