Not in the short term. I like the idea of the UI layer being a thin veneer
over API calls but that simply isn't the case for most commands, and
therefore testing 99% of the app just at API level isn't currently realistic.
The entry points for view handling are thin: builtins.tree_files() and
builtins.tree_files_for_add(). Perhaps we need to move those out of
builtins.py into their own module and have explicit tests for them.
Even then, I don't think we should underestimate the value of
end-to-end black-box testing.
