Is there a conflict for ensure_consistency alias in book Adopting Elixir?

goofansu

In the AUTOMATING YOUR CONSISTENCY CHECKS, there is an alias:

    def aliases do
      [
        "ensure_consistency": ["test", "dialyzer", "credo --strict", "inch", "coveralls"]
      ]
    end

When I tried in my own project, it complains:
** (Mix) "mix test" is running on environment "dev". If you are running tests along another task, please set MIX_ENV explicitly.

I suppose it should execute in MIX_ENV=test mix ensure_consistency, but in previous chapters, the deps are:

    defp deps do
 	  [
 	    {:credo, "~> 0.8.8", only: [:dev], runtime: false},
 	    {:dialyxir, "~> 0.5", only: [:dev], runtime: false},
 	    {:excoveralls, "~> 0.7.4", only: [:test], runtime: false},
 	    {:ex_doc, "~> 0.18", only: [:dev], runtime: false},
 	    {:inch_ex, "~> 0.5", only: [:dev, :test], runtime: false}
 	  ]
 	end

So the credo and dialyxir are available only in dev mode while excoveralls only in test mode, it seems existing a conflict.

Is there something wrong? Thanks

I changed the deps as following, and run MIX_ENV=test mix ensure_consistency, it works.

    defp deps do
 	  [
 	    {:credo, "~> 0.8.8", only: [:dev, :test], runtime: false},
 	    {:dialyxir, "~> 0.5", only: [:dev, :test], runtime: false},
 	    {:excoveralls, "~> 0.7.4", only: [:test], runtime: false},
 	    {:ex_doc, "~> 0.18", only: [:dev], runtime: false},
 	    {:inch_ex, "~> 0.5", only: [:dev, :test], runtime: false}
 	  ]
 	end

But “coveralls” cannot output anything. If I run mix converalls, it have the output.

I believe there is a :preferred_cli_env configuration you should set too.

Ah, yes, I have set :preferred_cli_env

defmodule Brightu.Mixfile do
  use Mix.Project

  def project do
    [
      app: :brightu,
      version: "0.0.1",
      elixir: "~> 1.4",
      elixirc_paths: elixirc_paths(Mix.env()),
      compilers: [:phoenix, :gettext] ++ Mix.compilers(),
      start_permanent: Mix.env() == :prod,
      aliases: aliases(),
      deps: deps(),
      dialyzer: [plt_add_deps: :transitive],
      test_coverage: [tool: ExCoveralls],
      preferred_cli_env: [
        coveralls: :test,
        "coveralls.html": :test,
        inch: :test,
        ensure_consistency: :test
      ]
    ]
  end

  # Configuration for the OTP application.
  #
  # Type `mix help compile.app` for more information.
  def application do
    [
      mod: {Brightu.Application, []},
      extra_applications: [:logger, :runtime_tools]
    ]
  end

  # Specifies which paths to compile per environment.
  defp elixirc_paths(:test), do: ["lib", "test/support"]
  defp elixirc_paths(_), do: ["lib"]

  # Specifies your project dependencies.
  #
  # Type `mix help deps` for examples and options.
  defp deps do
    [
      {:phoenix, "~> 1.3.2"},
      {:phoenix_pubsub, "~> 1.0"},
      {:phoenix_ecto, "~> 3.2"},
      {:postgrex, ">= 0.0.0"},
      {:phoenix_html, "~> 2.10"},
      {:phoenix_live_reload, "~> 1.0", only: :dev},
      {:gettext, "~> 0.11"},
      {:cowboy, "~> 1.0"},
      {:credo, "~> 0.9.1", only: [:dev, :test], runtime: false},
      {:dialyxir, "~> 1.0.0-rc.2", only: [:dev, :test], runtime: false},
      {:excoveralls, "~> 0.8", only: [:test], runtime: false}
      {:inch_ex, "~> 0.5", only: [:dev, :test], runtime: false},
    ]
  end

  # Aliases are shortcuts or tasks specific to the current project.
  # For example, to create, migrate and run the seeds file at once:
  #
  #     $ mix ecto.setup
  #
  # See the documentation for `Mix` for more info on aliases.
  defp aliases do
    [
      "ecto.setup": ["ecto.create", "ecto.migrate", "run priv/repo/seeds.exs"],
      "ecto.reset": ["ecto.drop", "ecto.setup"],
      test: ["ecto.create --quiet", "ecto.migrate", "test"],
      ensure_consistency: ["test", "dialyzer", "credo --strict", "inch", "coveralls"]
    ]
  end
end

When I run mix ensure_consistency, the coveralls seems not work. For example, I changed it to a typo word like imcoveralls, I expected it to report The task "imcoveralls" could not be found, but even no such error.

And inch has the same problem.

The output of mix ensure_consistency:
