我在调试Rails教程的Rspec代码时遇到问题。当我运行我的rspec代码时，我收到此错误：
1) Authentication authorization as non-admin user submitting a DELETE request to the Users#destroy action
Failure/Error: specify { expect(response).to redirect_to(root_url) }
Expected response to be a redirect to <http://www.example.com/> but was a redirect to <http://www.example.com/signin>.
Expected "http://www.example.com/" to be === "http://www.example.com/signin".
# ./spec/requests/authentication_pages_spec.rb:106:in `block (5 levels) in <top (required)>'
2) Authentication authorization as wrong user submitting a GET request to the Users#edit action
Failure/Error: specify { expect(response).to redirect_to(root_url) }
Expected response to be a redirect to <http://www.example.com/> but was a redirect to <http://www.example.com/signin>.

3) Authentication authorization as wrong user submitting a PATCH request to the Users#update action
Failure/Error: specify { expect(response).to redirect_to(root_url) }

# ./spec/requests/authentication_pages_spec.rb:95:in `block (5 levels) in <top (required)>'
我的/spec/requests/authentication_pages_spec.rb的代码是：
require 'spec_helper'
describe "Authentication" do
subject { page }
describe "signin page" do
before { visit signin_path }
it { should have_content('Sign in') }
it { should have_title('Sign in') }

end

describe "submitting a GET request to the Users#edit action" do

describe "submitting a DELETE request to the Users#destroy action" do
before { delete user_path(user) }
specify { expect(response).to redirect_to(root_url) }
end
end
end
end
我的utilities.rb的代码是：
include ApplicationHelper
def valid_signin(user)
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign in"
end
def sign_in(user, options={})
if options[:no_capybara]
# Sign in when not using Capybara.
remember_token = User.new_remember_token
cookies[:remember_token] = remember_token
user.update_attribute(:remember_token, User.encrypt(remember_token))
else
visit signin_path
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign in"
end
end
def valid_user()
fill_in "Name", with: "Example User"
fill_in "Email", with: "user@example.com"
fill_in "Password", with: "foobar"
fill_in "Confirmation", with: "foobar"
end
RSpec::Matchers.define :have_error_message do |message|
match do |page|
expect(page).to have_selector('div.alert.alert-error', text: message)
end
end
当我运行rails服务器时，一切都运行良好。
有趣的是，当我在服务器上运行以及运行实际测试时，我的日志不同。在服务器上，以用户ID 2身份登录，我得到了：

在我的test.log文件中，我看到了：

编辑1：这是我的signed_in_user代码：
private
def user_params
params.require(:user).permit(:admin, :name, :email, :password, :password_confirmation)
end
# Before filters
def signed_in_user
debugger
unless signed_in?
store_location
redirect_to signin_url, notice: "Please sign in."
end
end
def correct_user
@user = User.find(params[:id])
redirect_to root_path unless current_user?(@user)
end
def admin_user
redirect_to root_path unless current_user.admin?
end
def strict_signed_in_user
redirect_to root_url, notice: "You are already signed in." unless !signed_in?
end
Edit2 ：使用debugger我设法找到了一些错误：
F/Users/rasheedbustamam/Rails projects/sample_app/spec/support/utilities.rb:11
if options[:no_capybara]
[6, 15] in /Users/rasheedbustamam/Rails projects/sample_app/spec/support/utilities.rb
6 click_button "Sign in"
7 end
8
9 def sign_in(user, options={})
10 debugger
=> 11 if options[:no_capybara]
12 # Sign in when not using Capybara.
13 remember_token = User.new_remember_token
14 cookies[:remember_token] = remember_token
15 user.update_attribute(:remember_token, User.encrypt(remember_token))
(rdb:1) v l
self = #<RSpec::Core::ExampleGroup::Nested_1::Nested_3::Nested_2::Nested_2:0x00000109aeb1b8>
options = {:no_capybara=>true}
remember_token = nil
user = #<User:0x00000109af02f8>
值得注意的是，remember_token是nil这似乎是一个问题。
提前非常感谢！

根据测试结果，您的signed_in_user过滤器会导致重定向，表明登录失败。我建议通过您的控制器代码跟踪登录执行和/或在此处共享相关代码以供审核。
