gistfile1.ex

  defmodule Punk do
    def hip? do
      true
    end

    def hop? do
      hip?
    end
  end

  fact "mock with an arguments" do
    :meck.new(Punk, [:passthrough])
    :meck.expect(Punk, :hip?, fn -> false end)


    Punk.hip? |> falsey 
    #Passes

    Punk.hop? |> falsey 
    #Fails with: (UndefinedFunctionError) undefined function: Punk_meck_original.hop?/0
  end

To replicate:

Ensure Elixir is installed & atleast Erlang R16

brew install elixir

Then run:

git clone -b nested_mock git@github.com:josephwilk/amrita.git && cd amrita && MIX_ENV=test mix deps.get && mix test

Failing test: https://github.com/josephwilk/amrita/blob/nested_mock/test/integration/meck_test.exs

Using Meck through Elixir I'm not sure if its some interop issue, my misunderstanding or something else.

Removing the ? had no effect.

I get the following error:
