If it is invoked with None, it should return a false class-method emulator instead. For some reason, Python's documentation recommends to define descriptors' __get__ methods with the 'type' parameter as optional, despite the fact that Python itself never actually calls the descriptor that way. This is probably do to support 'foo.__get__(bar)' as an idiom. Let's make sure that the behavior is correct. Since we don't actually use the 'type' argument at all, this test calls it the idiomatic way to ensure that signature works; test_proxyInheritance verifies the how-Python-actually-calls-it signature. ceZdZdZdZy)>ProxyForInterfaceTests.test_proxyDescriptorGet..SampleFcd|_yr)calledrs rrzDProxyForInterfaceTests.test_proxyDescriptorGet..Sample.hello&s " rN)rrrrvrrrrSamplert#s F #rrwrr0N)r0r_ProxyDescriptorrz__get__rrorv)rrw fakeProxy testObjectpdfakeClassMethods rtest_proxyDescriptorGetz.ProxyForInterfaceTests.test_proxyDescriptorGets}" # # H X '   ( (* = I. 0@0@A**T* "  ))*rcGddttGfdd}t}||}|j|j dddd d |j|j d t dd fgy ) z Subclasses of the class returned from L{proxyForInterface} should be able to upcall methods by reference to their superclass, as any normal Python class can. ceZdZdZy)DProxyForInterfaceTests.test_proxyInheritance..YayableWrapperzI This class does not override any functionality.
