我有一个在浏览器中工作的简单登录系统。我最近将我的黄瓜测试切换为使用 selenium，因为我需要 ajax 调用，现在登录/身份验证步骤不再通过。该应用程序在 Firefox 和 Chromium 中仍可正常运行。

这是步骤和定义

features/authentication.features

Feature: Require Authentication
  In order to restrict access to the app
  A User
  Must be logged in

  Scenario: Accessing Tracks   
    Given I am not logged in   
    And I visit the "Tracks" page   
    Then I should see the "Welcome" page 
    And I should see "You need to be logged in to access this page"

  Scenario: Accessing Tracks when Logged in 
    Given I am logged in      
    And I visit the "Tracks" page   
    Then I should see the "Tracks" page

end

When(/^I log out$/) do         
  visit(logout_path)
end   

When(/^I should be logged out$/) do
  page.should have_title "Welcome"
  page.should have_text "Please log in"
end   

When(/^I am( not)? logged in$/) do |negative|
  if negative
    visit(logout_path)
  else
    create_and_login('anyone') 
    page.should have_title 'Welcome'
  end
end

修复方法是不将 selenium 设置为默认的 capybara 驱动程序，并使用 @javascript 标记需要 ajax 的测试。
