 
   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 `conn/3` helper:
+  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/2` returns a connection with the given request information already
+  `build_conn/3` returns a connection with the given request information already
   filled in.
 
   ## Recycling

  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!"
