How do I troubleshoot this error? - ruby-on-rails

Question

I'm working my way through Michael Hartl's Rails Tutorial and I am currently on chapter 8, in section 8.55. I am trying to trouble shoot a failure that I'm receiving via that test, which I can't figure out where to solve.
FAIL["test_current_user_returns_right_user_when_session_is_nil", SessionsHelperTest, 0.05582] test_current_user_returns_right_user_when_session_is_nil#SessionsHelperTest (0.06s)

My test code is using the following code.
require 'test_helper'
class SessionsHelperTest < ActionView::TestCase
def setup
#user = users(:kyle)
remember(#user)
end
test "current_user returns right user when session is nil" do
assert_equal #user, current_user
assert is_logged_in?
end
test "current_user returns nil when remember digest is wrong" do
#user.update_attribute(:remember_digest, User.digest(User.new_token))
assert_nil current_user
end
end
SessionsHelper module
module SessionsHelper
# Logs in the given user.
def log_in(user)
session[:user_id] = user.id
end
#Remembers a user in a persistent session.
def remember(user)
user.remember
cookies.permanent.signed[:user_id] = user.id
cookies.permanent[:remember_token] = user.remember_token
end
#Returns the user corresponding to the remember token cookie.
def current_user
if (user_id = session[:user_id])
#current_user ||= User.find_by(id: user_id)
elsif (user_id = cookies.signed[:user_id])
user = User.find_by(id: user_id)
if user && user.authenticated?(cookies[:remember_token])
log_in user
#current_user = user
end
end
end
#Returns the current logged-in user (if any).
def current_user
#current_user ||= User.find_by(id: session[:user_id])
end
#Returns true if the user is logged in, false otherwise.
def logged_in?
!current_user.nil?
end
def log_out
session.delete(:user_id)
#current_user = nil
end
# Forgets a persistent session.
def forget(user)
user.forget
cookies.delete(:user_id)
cookies.delete(:remember_token)
end
# Logs out the current user.
def log_out
forget(current_user)
session.delete(:user_id)
#current_user = nil
end
end

end
#Returns a random token.
def User.new_token
SecureRandom.urlsafe_base64
end
#Remembers a user in the database for use in persistent sessions
def remember
self.remember_token = User.new_token
update_attribute(:remember_digest, User.digest(remember_token))
end
#Returns true if the given token matches the digest.
def authenticated?(remember_token)
return false if remember_digest.nil?
BCrypt::Password.new(remember.digest).is_password?(remember_token)
end
# Forgets a user.
def forget
update_attribute(:remember_digest, nil)
end
end
Any ideas on what could have caused this?

Answer 1

You have two
def current_user
methods in module SessionsHelper
remove this one(which is old one and doesn't check for cookies presence):
#Returns the current logged-in user (if any).
def current_user
#current_user ||= User.find_by(id: session[:user_id])
end
it is being used in your test currently, because it is defined below updated one.
