我已经参考了链接http://railscasts.com/episodes/155-beginning-with-cucumber进行测试。

当我before_filter :authenticate_user!在我的控制器中使用时，我的所有案例都失败了，当我评论before_filter我的所有测试案例都通过了。我收到以下错误。

Scenario: Create Valid Article   
          Given I have no articles                                
          And I am on the list of articles                       
          When I follow "New Article"                             

 Unable to find link "New Article" (Capybara::ElementNotFound)
  ./features/step_definitions/article_steps.rb:25:in `/^I follow "([^\"]*)"$/'
  features/manage_articles.feature:15:in `When I follow "New Article"'

  And I fill in "article[title]" with "Spuds"        
  And I fill in "Content" with "Delicious potato wedges!" 
  And I press "Create"                                   
  Then I should see "New article created."                
  And I should see "Spuds"                                
  And I should see "Delicious potato wedges!"             
  And I should have 1 article

Then /^I should have ([0-9]+) articles?$/ do |count|
  Article.count.should == count.to_i
end

由于您的身份验证失败，因此您的测试场景应该类似于首先对用户进行身份验证......因为没有身份验证它不会进入文章列表页面，因此“新文章”链接尚未找到并出现该错误

Scenario: Create Valid Article 
      When I am on the login page
      Then I filled up username as "abc"
      Then I filled up password as "abc"
      Then I follow "login" 
      Given I have no articles                                
      And I am on the list of articles                       
      When I follow "New Article"

或者

 Scenario: Create Valid Article 
      Given User is authenticated        
      Given I have no articles                                
      And I am on the list of articles                       
      When I follow "New Article"

由于错误，capybara 在页面上找不到链接。所以根据@gotva，请检查页面上是否有“新文章”的链接。

正如您所说before_filter :authenticate_user!，这意味着您需要在尝试访问该页面之前登录。但是该功能中没有登录场景。

所以我建议你按照@Rajarshi Das 的建议在页面中添加登录场景。如果您的登录场景总是包含在每个功能中，那么您可以将其放在Background中。

Feature: Managing Articles

Background:
  Given user is logged in

Scenario: Create Valid Article   
  Given I have no articles                                
  And I am on the list of articles                       
  When I follow "New Article"                             
  And I fill in "article[title]" with "Spuds"        
  And I fill in "Content" with "Delicious potato wedges!" 
  And I press "Create"                                   
  Then I should see "New article created."                
  And I should see "Spuds"                                
  And I should see "Delicious potato wedges!"             
  And I should have 1 article            


common_steps.rb

def login user
  #stuff of login process
end

Given /^user is logged in$/ do
  @user = Factory.create(:user) #if you are using factory_girl
  login(@user)
end

希望有帮助！！！
