I just finished chapter 10 of the Ruby on Rails Tutorial, adding the ability to edit/update, index, and destroy users. Everything appears to be working properly in my app, but many of my tests are failing when I run RSpec.
我刚刚完成了Ruby on Rails教程的第10章，添加了编辑/更新，索引和销毁用户的功能。一切似乎都在我的应用程序中正常工作，但是当我运行RSpec时，我的许多测试都失败了。
I have the users_controller_spec set up exactly as the book does it and my application code is the same as well. Could one issue may be that I am using Rails 3.1.1 as opposed to Rails 3.0 which he uses in the book? It hasn't really been an issue for previous tests, just occasionally for a few different lines of code. The issues started appearing after I started section 10.2.1.
我设置的users_controller_spec与书的设置完全一样，我的应用程序代码也是一样的。一个问题可能是我使用Rails 3.1.1而不是他在书中使用的Rails 3.0？它对于以前的测试来说并不是一个问题，只是偶尔会出现几行不同的代码。在我开始第10.2.1节后，问题开始出现。
Here is the list of errors that I am seeing and please let me know if you need more info. Thanks!

UPDATE:
更新：
I solved 2 of the errors, but most are still persisting. One issue appears to be that when the test is trying to "get :index", it's not finding the correct page because of a redirect (to the /signin page). I did not institute any redirects (on purpose anyway), but maybe someone has an idea of how this might have happened and how it could be fixed?
我解决了2个错误，但大多数仍然存在。一个问题似乎是当测试试图“获取：索引”时，由于重定向（到/ signin页面），它找不到正确的页面。我没有建立任何重定向（无论如何），但也许有人知道这可能发生了什么以及如何解决？

I had the same issue and found the answer posted here.
我有同样的问题，发现这里的答案。
basically RSPEC needs both @current_user and current user to be set for sign_in and sign_out. Weird and annoying, but perhaps the reason one might consider using Devise in a production app!
基本上RSPEC需要为sign_in和sign_out设置@current_user和当前用户。奇怪而烦人，但也许是人们可能会考虑在生产应用程序中使用Devise的原因！

Providing your controller and test code would be helpful. But without them my guess would be that you are missing this in the before block for your failing tests:
提供控制器和测试代码会很有帮助。但是如果没有它们，我的猜测就是你在前面的块中错过了这个失败的测试：
@user = Factory(:user)
test_sign_in(@user)
The redirection is happening because of whatever authorization logic is being used in the tutorial, i think it is detailed in 10.11 and 10.12.
重定向正在发生，因为教程中使用了任何授权逻辑，我认为它在10.11和10.12中有详细说明。
This is a common gotcha i see in controller tests with auth, hopefully that's all that it is for you as well.
这是我在控制器测试中使用auth看到的常见问题，希望这也是它的全部内容。

Thanks for providing your code.
感谢您提供代码。
Here's a few things i noticed:
这是我注意到的一些事情：
1.) Failures 1-14, 19 are due to the user authentication not working, specifically signed_in?. Are your session controller tests passing? You should definitely make sure those pass before testing the users controller since it depends on that functionality.
1.）故障1-14,19是由于用户认证不起作用，特别是signed_in？。您的会话控制器测试是否通过？在测试用户控制器之前，您一定要确保它们通过，因为它取决于该功能。
2.) Failures 15-18 are because you probably didn't create the migration to add the boolean attribute in Listing 10.35 -or- you need to run the migration on your test database: rake db:test:prepare
2.）失败15-18是因为您可能没有创建迁移以添加清单10.35中的布尔属性 - 或者 - 您需要在测试数据库上运行迁移：rake db：test：prepare
Sorry i couldn't pin point all your problems but hopefully gives you a step in the right direction.

Check that deny_access in SessionsHelper is defined before the private block.
检查SessionsHelper中的deny_access是否在私有块之前定义。
The book has a typo that implies that you should put deny_access at the end of the module. Unfortunately this means that the function is defined as private.
这本书有一个拼写错误，暗示你应该把deny_access放在模块的末尾。不幸的是，这意味着该函数被定义为私有。
module SessionsHelper

end
end
The corrected code on the Railstutorial.org website is below:

See if that helps, I haven't completed the chapter, but this gets me through 10.2.1. Someone with more experience can comment on why this works. I read another solution that wrote around depending on before_filter to get rspec to pass.
