helpful_scripts - listen_for_event()

[ProbStub]

I have been playing with integration testing for my VRF1 code and adapted a little to what is in the repo. However, I was wondering how the rinkeby testing works without setting the WebsocketProvider.

Is there perhaps missing a piece in listen_for_enevtto the effect of:

PROVIDER = "wss://"+network.show_active()+".infura.io/ws/v3/"+getenv("WEB3_INFURA_PROJECT_ID")
    web3 = Web3(Web3.WebsocketProvider(PROVIDER))

Or did I miss something?
