Mockery

It's still under development. Everything is subject to change.

Installation

def deps do
  [
    {:mockery, "~> 0.1.0", only: :test}
  ]
end

Usage

  defmodule MyApp.UserService do
    def users, do: []
  end

  defmodule MyApp.TestUserService do
    use Mockery,
      module: MyApp.UserService
  end

  defmodule MyApp.UserController do
    @service Application.get_env(:my_app, :user_service, MyApp.UserService)

    def index do
      @service.users()
    end
  end

  # config/test.exs
  config :my_app,
    user_service: MyApp.TestUserService

  defmodule MyApp.UserControllerTest do
    use ExUnit.Case, async: true

    alias MyApp.UserController, as: Controller
    alias MyApp.UserService, as: Service

    describe "index" do
      test "not mocked" do
        assert Controller.index() == []
      end

      test "mocked" do
        Mockery.return(Service, :users, [:john, :donald])

        assert Controller.index() == [:john, :donald]
      end
    end
  end

TODOS

• basic functionality
• setup CI
• recompile when mocked module is changed
• way to override default function outputs
• docs
