I’m a big fan of rigorous unit testing. I believe most slow integrated tests can be replaced by unit tests using mocks, provided that one writes a good set of both unit and contract tests for all pieces of code. Good static type systems and checkers go a long way in ensuring contracts; unfortunately, we don’t have that luxury in Elixir.  When I found Mox I was hooked; I loved that it requires to make the contracts explicit as behaviours. However I was disappointed to find that even though...
