Rails Tutorial 8.2: Log in Log out - ruby-on-rails

Question

Working through the Rails Tutorial and in chapter 8 I can't get one of my tests to pass. Been checking around for hours... any help would be greatly appreciated.
ERROR["test_login_with_valid_information", UsersLoginTest, 2015-09-07 00:25:37 -0700]

Answer 1

I know it's been a while since originally posted, but I had exactly the same error and my problem was a typo (missing =) in
users.yml
michael:
name: Michael Example
email: michael#example.com
password_digest: <% User.digest('password') %>
where it should have been
michael:
name: Michael Example
email: michael#example.com
password_digest: <%= User.digest('password') %>

Answer 2

#PraveenGeorge is correct - you need to back track and review your code at least since the last time the tests passed. Based on the fact that the content of the two files you've shared match to the tutorial, the problem lies elsewhere (and, unfortunately, out of sight from us on SO).
Perhaps it's in user.rb where you def User.digest(string) or in sessions_helper.rb?

Answer 3

Dear #Travislogan : As the ruby on rails tutorial itself is self explanatory in most possible way, you might have missed some of the steps/code before you reached into the section 8.2. So please cross check all tests and your project code from at least the previous chapter to the current one , one more time.It will help you to find out the error in your code.
