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. c @ s e Zd ZdZdd� ZdS )z>ProxyForInterfaceTests.test_proxyDescriptorGet.<locals>.SampleFc S s d| _ d S r� )�calledr r r r rX 9 s zDProxyForInterfaceTests.test_proxyDescriptorGet.<locals>.Sample.helloN)r r r r� rX r r r r �Sample7 s r� rX r' N) rK r' r Z_ProxyDescriptorrN �__get__rX r� r� )r r� Z fakeProxyZ testObjectZpdZfakeClassMethodr r r �test_proxyDescriptorGet' s z.ProxyForInterfaceTests.test_proxyDescriptorGetc sp G dd� dt t��� G � fdd�d� �}t� }||�}| �|jddddd �d � | �|jd tddd �fg� d S ) 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. c @ s e Zd ZdZdS )zDProxyForInterfaceTests.test_proxyInheritance.<locals>.YayableWrapperzI This class does not override any functionality.
