Our test coverage of NodeBalancers has been lacking for a long time and your additional coverage here is awesome to have!

Confirmed the config panel Algorithm field looks good now and helper text across the form is consistent. Thanks for tackling this one. The original typo had been around for 5+ years - I remember checking when I made the ticket.
