Phoenix: Mix phoenix.gen.html生成失败的测试

Question

我先运行mix phoenix.gen.html Topic topics title used:boolean，然后运行mix ecto.migrate来运行迁移。

我将此添加到我的路由中

defmodule ParrotApi.Router do
  use ParrotApi.Web, :router

  pipeline :browser do
    plug :accepts, ["html"]
    plug :fetch_session
    plug :fetch_flash
    plug :protect_from_forgery
    plug :put_secure_browser_headers
  end

  pipeline :api do
    plug :accepts, ["json"]
  end

  scope "/", ParrotApi do
    pipe_through :browser # Use the default browser stack

    resources "/topics", TopicController #<-----------------------------
    get "/", CallController, :index
  end
end

在那之后，我运行了主题控制器的测试，其中一些失败了：

➜  parrot-api git:(master) ✗ mix test test/controllers/topic_controller_test.exs:13
Including tags: [line: "13"]
Excluding tags: [:test]

以下是我的依赖项列表：

 defp deps do
   [
     {:phoenix, "~> 1.2.1"},
     {:phoenix_pubsub, "~> 1.0"},
     {:phoenix_ecto, "~> 3.0"},
     {:phoenix_slime, "~> 0.8.0"},
     {:postgrex, ">= 0.0.0"},
     {:phoenix_html, "~> 2.6"},
     {:phoenix_live_reload, "~> 1.0", only: :dev},
     {:gettext, "~> 0.11"},
     {:cowboy, "~> 1.0"},
     {:poison, "~> 2.0"},
     {:timex, "~> 3.0"},
  ]

这是怎么回事？

我不得不将以下代码添加到我的test.exs文件中：

config :phoenix, :template_engines,
 slim: PhoenixSlime.Engine,
