Ruby on Rails Tutorial 3.2 by Michael Hartl Chapter 9. authentication_pages_spec.rb doesn't see sign_in method in utilities.rb - railstutorial.org

Question

This is my first question on StackOverflow, so bear with me ...
When I use the authentication_pages_spec.rb in Listing 8.6 my tests pass.
Then I define the sign_in method in 'spec/support/utilities.rb' and modify authentication_pages_spec.rb according to Listing 9.5 and, when running
$ bundle exec rspec spec/requests/authentication_pages_spec.rb -e "Authentication"
I get
1) Authentication signin with valid information
Failure/Error: before { sign_in user }
NoMethodError:
undefined method `sign_in' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_2::Nested_2:0x007fc585a87cd8>
# ./spec/requests/authentication_pages_spec.rb:31:in `block (4 levels) in <top (required)>'
for all the six tests under "with valid information".
It seems that the spec doesn't see the sign_in function and needs some declaration, anyhow I couldn't find where this is done in the Michael Hartl's code on Github.
Any help is really appreciated.

Answer 1

Just Restart spork and it should work :)

Answer 2

Hartl explains the sign_in helper almost immediately after that in Listing 9.6

Answer 3

I encountered the exact same error messages, based on a subtle mis-placement of an end. Sharing here, in case others run into the same test failures and are seeking a possible solution.
My mistake was in how I authored utilities.rb, which was:
include ApplicationHelper
RSpec::Matchers.define :have_error_message do |message|
match do |page|
page.should have_selector('div.alert.alert-error', text: 'Invalid')
end
def sign_in(user)
visit signin_path
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign in"
# # Sign in when not using Capybara as well.
# cookies[:remember_token] = user.remember_token
end
end
What the final end needs to be after the RSpec::Matchers block and should read like this:
include ApplicationHelper
RSpec::Matchers.define :have_error_message do |message|
match do |page|
page.should have_selector('div.alert.alert-error', text: 'Invalid')
end
end
def sign_in(user)
visit signin_path
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign in"
# # Sign in when not using Capybara as well.
# cookies[:remember_token] = user.remember_token
end
