Rspec + Capybara:undefined last_response

Question

我正在使用Rspec + Capybara设置我的测试环境,但是我得到了这个未定义的last_response.我在网上搜索和SO.我发现了一些关于版本的东西,使用git repo而不是rubygem源等......但它并没有改变我的线索.

这里的回溯:rspec --backtrace spec/controllers/api/plist/providers_listing_spec.rb失败:

1) Api::Plist::ProvidersController should return a successfull plist containing a list of providers
 Failure/Error: last_response.status.shoud be_success

这是我测试的gem配置:

gem 'ruby-prof' # perf
gem 'rspec-rails', :git => 'git://github.com/rspec/rspec-rails.git'
gem 'shoulda' # Shoulda
gem 'factory_girl_rails' #=> mocking
gem 'capybara', :git => "http://github.com/jnicklas/capybara.git" 
gem 'database_cleaner'

gem 'rb-fsevent', :require => false if RUBY_PLATFORM =~ /darwin/i #guard mac dependency

gem 'guard-livereload' # browser reloading
gem 'guard-rspec'
gem 'guard-test'
gem 'growl' #grow notification

我正在使用database_clearner来处理mongo db ...

直到现在我还没有真正使用:

require 'spec_helper'

describe Api::Plist::ProvidersController, :type => :api do
  let (:user) {Factory(:confirmed_user)}
  let (:api_account) {user.new_api_account}
  let (:api_token) {api_account.authentication_token}
  let (:email) {api_account.email}

  it "should return a successfull plist containing a list of providers" do
    get 'index', :auth_token => api_token, :email => email
    last_response.status.shoud be_success
    last_response.body.should eql({:sucess => true}.to_plist.to_s)
  end
end

以下是我已经阅读的帖子,即使他们主要谈论webrat ......:

• https://github.com/rspec/rspec-rails/issues/174
• ...

如果有人知道该怎么做,使用哪个宝石版本？

Answer 1

你可以加...

config.include Rack::Test::Methods

到你的spec_helper.rb.这将为所有测试 添加last_response ...和其他方法....

由于您可能不需要这样做,因此更好的想法是根据需要从模块中包含它们.在spec/support文件夹中创建一个帮助器模块.然后添加以下代码:

module ApiHelper
  include Rack::Test::Methods
  def app
    Rails.application
  end
end

RSpec.configure do |c|
  c.include ApiHelper, type: :api
end

现在:type => :api你将实际做一些事情,即将Rack :: Test :: Methods添加到该规范中.

describe Api::Plist::ProvidersController, :type => :api do
  # etc
end
