我正在完成本教程并得到此错误
Failures:
1) Authentication signin 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/authentication_pages_spec.rb:48:in `block (4 levels) in <top (required)>'
我已经彻底研究了这个问题，虽然有类似的问题，但我尝试了他们的解决方案，但他们没有用。
以下是相关代码：
会话控制器
class SessionsController < ApplicationController
def new
end
def create
user = User.find_by_email(params[:session][:email].downcase)
if user && user.authenticate(params[:session][:password])
# Sign the user in and redirect to the user's show page.
sign_in user
redirect_to user
else
flash.now[:error] = 'Invalid email/password combination'
render 'new'
end
end
def destroy
sign_out
redirect_to root_url
end
end
会话助手
module SessionHelper
def sign_in(user)
remember_token = User.new_remember_token
cookies.permanent[:remember_token] = remember_token
user.update_attribute(:remember_token, User.encrypt(remember_token))
self.current_user = user
end
def signed_in?
!current_user.nil?
end
def current_user=(user)
@current_user = user
end
def current_user
remember_token = User.encrypt(cookies[:remember_token])
@current_user ||= User.find_by_remember_token(remember_token)
end
def sign_out
self.current_user = nil
cookies.delete(:remember_token)
end
end

任何有关错误以及如何解决问题的帮助和解释都将非常感激。
EDIT。
水豚错误消失但现在我有了一个新错误，
故障：
1) Authentication signin with valid information followed by signout
Failure/Error: it { should have_selector( "title", :content => user.name)}
NoMethodError:
undefined method `it' for #<RSpec::Core::ExampleGroup::Nested_2::Nested_2::Nested_2::Nested_1:0xb4063c4>
# ./spec/requests/authentication_pages_spec.rb:42:in `block (4 levels) in <top (required)>'
以下是身份验证页面规范的编辑版本
require 'spec_helper'
describe "Authentication" do
.
.
.
.
describe "with valid information" do
let(:user) { FactoryGirl.create(:user) }
before do
fill_in "Email", with: user.email.upcase
fill_in "Password", with: user.password
click_button "Sign in"
#it { should have_title(user.name) }
#it { should have_selector('title', text: user.name) }
it { should have_selector( "title", :content => user.name)}
it { should have_link('Profile', href: user_path(user)) }
it { should have_link('Sign out', href: signout_path) }
it { should_not have_link('Sign in', href: signin_path) }
end
describe "followed by signout" do
before { click_link "Sign out" }
it { should have_link('Sign in') }
end
end
end
end
这里有什么问题？我的语法是正确的，并且该行之前没有给出错误，为什么现在呢？任何帮助和解释为什么会发生这种情况将不胜感激。

您尚未登录。检查该失败的describe子句的嵌套/缩进，您会发现您已经过早地使用end阻止了“有效信息”阻止it单行。
