How to run Pytest for zeep while offline?

Question

I'm having a hard time testing zeep actions while offline. I'm using pytest-vcr to record the initial test. When I run my tests a subsequent time, they fail even though a cassette exists for the interaction. I suspect that zeep tries to communicate to the server before I call RISClient.nodes(). I thought it did so to download the WSDL, so I implemented a local_wsdl parameter in RISClient to make the WSDL available locally. However, after testing with that argument set to True, I get the following error: executeCCMSQLStatement Error: HTTPSConnectionPool(host='x.x.x.x', port=8443): Max retries exceeded with url: /realtimeservice2/services/RISService (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x00000166EB1701D0>: Failed to establish a new connection: [WinError 10065] A socket operation was attempted to an unreachable host')).

When I test with local_wsdl set to False, the error that I get is: E requests.exceptions.ConnectionError: HTTPSConnectionPool(host='x.x.x.x', port=8443): Max retries exceeded with url: /realtimeservice2/services/RISService?wsdl (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x0000024C1C5EBED0>: Failed to establish a new connection: [WinError 10065] A socket operation was attempted to an unreachable host'))

Why is my test failing offline? And, how can I get it to pass?
