'Rails Failure ---expected +++ actual @@ -1 +1 @@

I am working on the Michael Hartl tutorial. When running my test, I get the following failure:

1) Failure:
SessionsHelperTest#test_current_user_returns_right_user_when_session_is_nil
 [/home.../myapplication/test/helpers/sessions_helper_test.rb:11]:
--- expected
+++ actual
@@ -1 +1 @@
-#<User id:... >
+nil

Could anyone help make sense of this failure especially the following:

--- expected
+++ actual
@@ -1 +1 @@

Is there any official documentation from rails that gives guidance on those find of failure message? I have not found any. Thanks.

I do not know this tutorial and I don't know almost nothing of test but I think you have a error in your app. You get a nil output +nil and the expected output is a User element -#<User id:... >

Maybe you have wrong User.where clause

If you put more info I can try help more

My problem was that I had def current_user twice in app/helpers/sessions_helper.rb and one of them was outdated.
