Rails 3 +Devise + RSpec：未定义的方法“访问”答案

【问题标题】：Rails 3 +Devise + RSpec: undefined method 'visit'Rails 3 +Devise + RSpec：未定义的方法“访问”
【发布时间】：2012-06-14 12:56:24
【问题描述】：

我遇到了奇怪的问题。我以前从未使用过 Devise gem。所以，我尝试编写简单的 RSpec 测试：

require 'spec_helper'

describe "Admins" do
  before(:each) do
    @email = "test@test.ru"
    user = FactoryGirl.create(:user, :email => @email )
  end

  describe "sign in/out" do
    describe "success" do
      it "should sign a user in and out" do
        visit new_user_session_path
      end
    end
  end
end

我收到这样的错误：

  1) Admins sign in/out success should sign a user in and out
     Failure/Error: visit new_user_session_path
     NoMethodError:
       undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1::Nested_1:0x007fb2b7e393d0>
     # ./spec/requests/admins_spec.rb:12:in `block (4 levels) in <top (required)>'

Finished in 0.05646 seconds

我的工厂：

FactoryGirl.define do
  factory :user do |user|
    user.admin true
    user.password "qwerty"
    user.sequence(:email) { |n| "user#{n}@user.com" }
  end
end

路线：

        new_user_session GET    /users/sign_in(.:format)       devise/sessions#new
            user_session POST   /users/sign_in(.:format)       devise/sessions#create
    destroy_user_session DELETE /users/sign_out(.:format)      devise/sessions#destroy
           user_password POST   /users/password(.:format)      devise/passwords#create
       new_user_password GET    /users/password/new(.:format)  devise/passwords#new
      edit_user_password GET    /users/password/edit(.:format) devise/passwords#edit
                         PUT    /users/password(.:format)      devise/passwords#update
cancel_user_registration GET    /users/cancel(.:format)        devise/registrations#cancel
       user_registration POST   /users(.:format)               devise/registrations#create
   new_user_registration GET    /users/sign_up(.:format)       devise/registrations#new
  edit_user_registration GET    /users/edit(.:format)          devise/registrations#edit
                         PUT    /users(.:format)               devise/registrations#update
                         DELETE /users(.:format)               devise/registrations#destroy

【问题讨论】：

你在 spec_helper 中 require 'capybara/rspec' 了吗？

标签： ruby-on-rails ruby ruby-on-rails-3 rspec devise

【解决方案1】：

将所有使用 capybara 的测试从规范/请求移至规范/功能。

【解决方案2】：

visit 是 capybara 方法，而不是 Rspec。您必须将 capybara gem 添加到您的 Gemfile 中，在 spec_helper 中运行 bundle 和 require 'capybara/rspec'，就像 ArcaneRain 指出的那样。

【解决方案3】：

你必须将 Capybara DSL 添加到 spec_helper

.
.
.
RSpec.configure do |config|
  .
  .
  .
  config.include Capybara::DSL
end
