Test the socket interaction by mocking the socket

[gerw]

This provides almost 100% coverage of __init__.py. I am not sure about the missing lines. Sockets are weird, in particular checking whether a socket is closed / no longer usable.

Also the struct.error is not sensible in my opinion, but this should be discussed elsewhere.

Edit: And with the tests, I found a typo :)

Nice 😎

I was tempted to implement tests for __init__.py but failed on mocking socket.socket, good work @gerw
