   and pass an atom representing the action to dispatch:
 
       @endpoint MyAppWeb.HomeController
-    
+
       test "says welcome on the home page" do
         conn = get(build_conn(), :index)
         assert conn.resp_body =~ "Welcome!"


  `Phoenix.ConnTest` typically works against endpoints. That's the preferred way
  to test anything that your router dispatches to:
  
      @endpoint MyAppWeb.Endpoint
      
      test "says welcome on the home page" do
        conn = get(build_conn(), "/")
        assert conn.resp_body =~ "Welcome!"


  Under other circumstances, you may be testing a view or another layer that
  requires a connection for processing. For such cases, a connection can be
  created using the `build_conn/3` helper:

      MyApp.UserView.render("hello.html", conn: build_conn(:get, "/"))

  While `build_conn/0` returns a connection with no request information to it,
  `build_conn/3` returns a connection with the given request information already
  filled in.
