Thanks @alteholz! I would generally say going for 100% is counter intuitive, at this point the most beneficial thing would be to add some tests that don't mock the server, but actually test against it.

OTOH, we also have this issue of potentially deprecating alfalfa, so I would not pour much efforts into this module: #1285
