POHartl Ruby-on-Rails Tutorial (3.2), Section 8.2.6 - Sign out link not returning anything
text
Body
copied!<p>I'm getting the following error after completing the sign out part of the tutorial:</p> <pre><code>Failures: 1) User pages signup with valid information after saving the user Failure/Error: it { should have_link('Sign out') } expected link "Sign out" to return something # ./spec/requests/user_pages_spec.rb:49:in `block (5 levels) in <top (required)>' Finished in 1.15 seconds 48 examples, 1 failure Failed examples: rspec ./spec/requests/user_pages_spec.rb:49 # User pages signup with valid information after saving the user </code></pre> <p>I had more errors before, but I ended up rearranging the order of items in the authentication_pages_spec.rb.
