Programming Phoenix 1.4

Authenticating a Test Socket

Most of our channels code relies on an authenticated user. We’ll start our tests with the socket authentication. Let’s do that now.

Create a rumbl_umbrella/apps/rumbl_web/test/channels/user_socket_test.exs file containing:

testing_otp/listings/rumbl_umbrella/apps/rumbl_web/test/rumbl_web/channels/user_socket_test.exs

defmodule RumblWeb.Channels.UserSocketTest do
  use RumblWeb.ChannelCase, async: true
  alias RumblWeb.UserSocket

  test "socket authentication with valid token" do 
    token = Phoenix.Token.sign(@endpoint, "user socket", "123")

    assert {:ok, socket} = connect(UserSocket, %{"token" => token}) 
    assert socket.assigns.user_id == "123"
  end

 test ...
