user_pages_spec.rb
describe "with valid information" do
before do
fill_in "Name", with: "Example User"
fill_in "Email", with: "user#example.com"
fill_in "Password", with: "foobar"
fill_in "Confirmation", with: "foobar"
end
it "should create a user" do
expect { click_button submit }.to change(User, :count).by(1)
end
describe "after saving the user" do
before { click_button submit }
let(:user) { User.find_by_email('user#example.com') }
it { should have_selector('title', text: user.name) }
it { should have_selector('div.alert.alert-success', text: 'Welcome') }
it { should have_link('Sign out') }
end
describe "followed by signout" do
before { click_link "Sign out" }
it { should have_link('Sign in') }
end
end
The failure is:
1) User pages signup with valid information followed by signout
Failure/Error: before ( click_link "Sign out" )
Capybara::ElementNotFound:
no link with title, id, or text 'Sign out' found
(eval):2:in 'click_link'
./spec/requests/user_pages_spec.rb:63:in 'block (5 levels) in (top (required))'
Following the create user process manually it appears to work. The link is in a drop down menu if maybe that might have something to do with it? This is at the point in the MHartl rails tutorial where he says all tests should pass.

Answer 1

The suspect code apparently needs to be nested inside the inside the previous describe
describe "after saving the user" do
before { click_button submit }
let(:user) { User.find_by_email('user#example.com') }
it { should have_selector('title', text: user.name) }
it { should have_selector('div.alert.alert-success', text: 'Welcome') }
it { should have_link('Sign out') }
describe "followed by signout" do
before { click_link "Sign out" }
it { should have_link('Sign in') }
end
end

Answer 2

The before block in the last describe hasn't yet created the user. This is why the user (which doesn't exist yet) isn't currently signed in, thus no "sign out" link.
One possible solution is to click_button 'submit' in the before block. Another is to skip the sign out in the before block altogether, since there is no user signed in at that point.

Answer 3

Yes, it should be nested inside the previous describe. I can confirm this also works for the Rails 4 version of the tutorial.
