Solve the following python programming problem given the following code:
@ fixture (scope = 'module') 
def protocol_fake(request) : 
    uuid4_patcher = patch ('uuid.uuid4') 
    uuid4_mock = uuid4_patcher.start () 
    uuid4_mock.return_value = uuid.UUID ('11111111-1111-1111-1111-111111111111') 
    from winrm.protocol import Protocol 
    protocol_fake = Protocol (endpoint = 'http://windows-host:5985/wsman', transport = 'plaintext', username = 'john.smith', password = 'secret') 
    protocol_fake.transport = TransportStub () 
    def uuid4_patch_stop() : 
        uuid4_patcher.stop () 
request.addfinalizer (uuid4_patch_stop) 
    return uuid4_mock
