Test public functions

You mean private right?

@andrelip

Moving that to a separated module just to test them without exposing to the API is very boring and very repetitive.

I do actually like this because it forces me to separate the public API from the private one by have a module for each one. A feature related to that I’m eager to see is the @module_visible_to discussed here: Proposal: Private modules (general discussion)
