Cucumber Help in Rails 3

Question

我对cucumber和rspec很新，但是有一些rails和ruby的理解。

有问题的宝石有：设计，Declarative_Authorization和role_model

Rails 3的是什么我使用和Ruby 1.9.2-RC2

记得我不知道我在做什么

我写了一个特点：

Feature: As the administrator of the site give me quick access to information 
    In order to do lots of stuff 
    As an administrator 
    I want to see reports and stuff 

    Background: 
    Given a logged in user with a role of "admin" 

    Scenario: Admin can see links 
    Given I am on the admin dashboard page 
    Then I should see all admin links 

随着一些网站的步骤：

module AdminDashboardHelpers 

    def current_user_session 
    return @user_session if defined?(@user_session) 
    @user_session = user_session 
    end 

    def current_user 
    return @current_user if defined?(@current_user) 
    @current_user = current_user_session && current_user_session.user 
    end 

    def admin_signed_in? 
    @user = current_user 
    @user.has_role?(:admin) 
    end 
end 

World(AdminDashboardHelpers) 


Given /^a logged in user with a role of "([^\"]*)"$/ do |role| 
    visit new_user_session_path 
    fill_in "Login", :with => "iam" 
    fill_in "Password", :with => "secret" 
    click_button "Log in" 
    admin_signed_in? 
    #@current_user.should has_role?(role) 
end 

Then /^I should see all admin links$/ do 
    pending # express the regexp above with the code you wish you had 
end 

我的问题是，当我运行的功能，我收到一个错误说的#Cucumber :: Rails的::全球 未定义的局部变量或方法`USER_SESSION”：0x8077e1f8

我的假设下该user_session是一个设计来的方法。 如何测试用户是否具有某种特定角色？

或者更好的是，我该如何告诉黄瓜有关由宝石提供的rails应用程序的方法？ 谢谢你的时间，这是不胜感激。 --iAm

通常情况下，你不应该在黄瓜做这种有点测试，它太高级别。你通常会在你的规格中做这些，而不是你的功能。在黄瓜里，你正在浏览一个模拟浏览器，所以你不必设置所有的帮助者等等。只需像访问用户一样访问Web应用程序，然后登录。堆栈应该完成剩下的工作..我正在使用设计，这里是我设置管理员的方式。

Given /^I have one\s+administrator "([^\"]*)" with email "([^\"]*)" and password "([^\"]*)"$/ do |name,email, password| 
    Administrator.new(:email => email, 
        :username=>name, 
        :password => password, 
        :password_confirmation => password).save! 
end 

Given /^I am an Authenticated Administrator$/ do 
    name = 'admin' 
    email = 'admin@inoc.net' 
    password = 'secret!' 

    Given %{I have one administrator "#{name}" with email "#{email}" and password "#{password}"} 
    And %{I go to the administrator login page} 
    And %{I fill in "administrator_username" with "#{name}"} 
    And %{I fill in "administrator_password" with "#{password}"} 
    And %{I press "Sign in"} 
end 

Given /^I have not authenticated as an+ "([^"]*)"$/ do |role| 
    visit("/#{role}s/sign_out") 
end 

至于测试某个角色，你可以在rspec中做，而不是在黄瓜。您在黄瓜测试的方式是转到只有该角色可以看到的页面，并确保您可以看到它，然后再进行一次测试，该页面应该无法看到，并确保获得您期待的错误。
