Cucumber 和 Devise，重定向太多？

Question

我正在尝试用黄瓜为 Devise 创建一个测试。这是我的功能

Feature: Login to locomotive
  In order to login to locomotive
  As a user 
  I want to be able to use Locomotive

Scenario: Login to locomotive
    Given I am a authenticated user
    Then I should see "logged in as <email>"
    Then show me the page

，这是我的用户步骤

Given /^I am not authenticated$/ do
  visit('/users/sign_out') # ensure that at least
end

Given /^I have one\s+user "([^\"]*)" with password "([^\"]*)" and username "([^\"]*)"$/ do |email, password, username|
  @user = User.new(:email => email,
           :username => username,
           :first_name => 'Josh',
           :last_name => 'Crowder',
           :password => password,
           :password_confirmation => password).save!
end

Given /^I am a authenticated user$/ do
  email = '[email protected]'
  username = 'josh'
  password = 'secretpass'

  Given %{I have one user "#{email}" with password "#{password}" and username "#{username}"}
  And %{I go to login}
  And %{I fill in "user_login" with "#{email}"}
  And %{I fill in "user_password" with "#{password}"}
  And %{I press "Sign in"}
end

我收到此错误消息

F--

我不知道为什么会发生这种情况，有什么想法吗？

Answer 1

可能有很多事情——如果没有更多代码就无法判断。一些可能性：

• 您是否需要对登录页面进行身份验证？这会让你陷入循环。您想要从身份验证解决方案中排除“打开”页面（例如登录），
• 您可以将“然后向我显示”页面放在更高的位置，这样您就可以准确看到发生了什么，
• 您可以将其重置回默认值通过注释掉其他路由来验证解决方案（例如设计）只是为了看看发生了什么

当您通过浏览器尝试时会发生什么？
