这是我的mix.exs

defmodule HelloPhoenix.Mixfile do
use Mix.Project

def project do
[app: :hello_phoenix,
 version: "0.0.1",
 elixir: "~> 1.0",
 elixirc_paths: elixirc_paths(Mix.env),
 compilers: [:phoenix, :gettext] ++ Mix.compilers,
 build_embedded: Mix.env == :prod,
 start_permanent: Mix.env == :prod,
 aliases: aliases,
 deps: deps]
end

# Configuration for the OTP application.
#
# Type `mix help compile.app` for more information.
def application do
     [mod: {HelloPhoenix, []},
     applications: app_list(Mix.env) ]
 end

    def app_list do
    [:phoenix, :phoenix_html, :cowboy, :logger, :gettext, :phoenix_ecto, :postgrex]
end

    def app_list(:test), do: [:hound | app_list]
def app_list(_),     do: app_list


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

  # Specifies your project dependencies.
  #
  # Type `mix help deps` for examples and options.
  defp deps do
[{:phoenix, "~> 1.1.4"},
 {:postgrex, ">= 0.0.0"},
 {:phoenix_ecto, "~> 2.0"},
 {:phoenix_html, "~> 2.4"},
 {:phoenix_live_reload, "~> 1.0", only: :dev},
 {:gettext, "~> 0.9"},
 {:cowboy, "~> 1.0"},
{:hound, "~> 0.8"}]
  end

  # Aliases are shortcut 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"]]
  end
 end

这是我的config/config.exs

# Define your application's host and port (defaults to "http://localhost:4001")
#config :hound, app_host: "http://localhost", app_port: 4000

# Start with selenium driver (default)
config :hound, driver: "selenium"

# Use Chrome with the default driver (selenium)
#config :hound, browser: "chrome"

# Start with default driver at port 1234 and use firefox
#config :hound, port: 1234, browser: "firefox"

# Start Hound for PhantomJs
#config :hound, driver: "phantomjs"

# Start Hound for ChromeDriver (default port 9515 assumed)
#config :hound, driver: "chrome_driver"

测试/sample_test.exs

    defmodule HelloPhoenix.SampleTest do
  use HelloPhoenix.ConnCase

  # Import Hound helpers
  use Hound.Helpers

  # Start a Hound session
  hound_session
    IO.puts "hai"
  test "GET /" do
    navigate_to("http://localhost:4000")
    :timer.sleep(5000) # puts server to sleep
    assert page_source =~ "Welcome to Phoenix"
  end
end

配置/test.exs

# We don't run a server during test. If one is required,
# you can enable the server option below.
config :hello_phoenix, HelloPhoenix.Endpoint,
  http: [port: 4000],
  server: true

启动 webdriver 服务器（一次尝试所有这些）

  1. java -jar selenium-server-standalone-2.48.2.jar

  2. java -jar selenium-server-standalone-2.49.0.jar

  3. java -jar selenium-server-standalone-2.52.0.jar

  4. docker run -it -p 4444:4444 danielfrg/selenium

  5. docker run --privileged -p 4444:4444 -p 5999:5999 -d vvoyer/docker-selenium-firefox-chrome

每次运行应用程序时都会出现此错误：

为了完整起见，万一有人遇到类似问题，我将做一个总结：

当 Erlang 返回:econnrefused错误时，表示连接存在问题。以下适用于任何编程语言，因为它是一个网络问题：

  • 您的网络接口已关闭。解决方法：连接接口。
  • 您正在尝试连接到错误的地址和/或端口。解决方案：查看您的代码或配置以检查 IP 地址和端口是否正确。还要检查远程主机是否实际上位于该 IP 地址中并侦听该端口中的连接。
  • 您被防火墙阻止。解决方案：这是一个更复杂的问题，因为它取决于您如何部署和测试您的应用程序。
  • 从运行应用程序的主机无法访问远程主机。解决方案：这也是一个更复杂的问题，但对于初学者来说，您可以检查您的远程主机是否在专用网络中：
    • 在接入点中配置适当的端口转发。
    • 如果它是 VM，请将来宾操作系统的虚拟网络接口连接到桥接适配器而不是 NAT 适配器，并使用与主机操作系统相同的网络接口。如果您的路由器/接入点中没有启用 DHCP，那么您应该在与您的主机相同的网络中为您的访客机器分配一个新的 IP 地址。Settings > Network在 Virtualbox 中，您可以在.*中配置适配器
