黄瓜找不到路线？这可能是一个很大的新问题

Question

Rails3 app与Rspec2和Cucumber

黄瓜

Given /^that a user is logged in$/ do
  current_user = User.first
  render new_user_post_path(current_user)
end

的routes.rb

map.resources :users do |users|
  users.resources :posts, :collection => {:view => :get}
end

posts_controller_spec

describe PostsController do
  describe "#new" do
    it "should be successful" do
      get :new
      response.should be_success
    end
  end
end

我的第一部大史诗失败

(::) failed steps (::)

No route matches {:controller=>"posts", :action=>"new"} (ActionController::RoutingError)
./features/step_definitions/tasklist_steps.rb:3:in `/^that a user is logged in$/'
features/tasklist.feature:7:in `Given that a user is logged in'

Failing Scenarios:
cucumber features/tasklist.feature:6 # Scenario: List SubmitLink

1 scenario (1 failed)
3 steps (1 failed, 2 skipped)

对不起，我太新了。这是我第一次尝试黄瓜。 ：（

首先，在Rails 3路由中不推荐使用地图，你可能应该有这样的东西。

resources :users do 
    resources :posts
end

我通常编写我的赠品的方式，我遵循用户实际采用的路径，在测试数据库中创建用户，然后实际进入登录页面并登录，以便在应用程序中正确设置所有内容

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

Given /^I am an authenticated user$/ do
  name = 'exmample'
  email = 'example@example.com'
  password = 'secret!'

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

我用以下方式使用它：

Feature: 
  In order to reboot my crappy/POS equipment without bothering the awesome Noc Monkeys
  I would like to login to a webpage and see the status of and control the outlets on my equipment

  Background: Valid and authenticated user with at least one outlet to control
    Given I am an authenticated user

  @ok
  Scenario: Viewing All outlets
    Given I am able to control an outlet with index "1"
    And I am on the home page
    Then I should see "server_1"

另外，通常我不会在黄瓜步骤中调用渲染。由于您正在使用模拟浏览器（假设是webrat / capybara），您将visit path_to(page_name)。
