Publicist

Publicist is a module which, when in the test environment, remaps defp to def.

Usage

defmodule MyModule do
  use Publicist # use before any def statements
  defp my_priv_function do
    0
  end
end

Now you can test the private function:

defmodule MyModule.Test do
 use ExUnit.Case

 test "my_priv_function returns 0" do
   assert my_priv_function() === 0
 end
end

Installation

Publicist can be installed by adding publicist to your list of dependencies in mix.exs:

def deps do
  [{:publicist, "1.0.0"}]
end
