Hi there - I had a follow up action from a backlog grooming meeting today regarding https://phabricator.wikimedia.org/T133023.
We're taking the discussion about this task to mobile-l and qa where we can make sure our discussion is documented and also get some additional opinions.
Proper test coverage and test coverage maintenance is a mildly complex topic, to put it lightly, but let's see if we can discuss here on mobile-l and qa lists and figure out how to tackle these sorts of tasks.
