爲什麼我的控制器的spec文件找不到post方法？

Question

在/spec/controllers/postbacks_controller_spec.rb，我有：

require 'spec_helper' 
describe PostbacksController, :type => :controller do 
    include RSpec::Rails::ControllerExampleGroup 
    describe "receive" do 
    etc etc ... ... etc etc 
    post "postbacks/#{@postback.id}/receive", @parameters 
    @postback.content.should == @parameters 
    end 
end 

爲什麼我得到下面的錯誤？

NoMethodError: undefined method `post' for # 

的Gemfile包括：

group :test do 
    gem "binding_of_caller" 
    gem "capybara" 
    gem "database_cleaner" 
    gem "launchy" 
    gem "respec" 
    gem "rspec-rails" 
    gem "parallel_tests" 
    gem "zeus-parallel_tests" 
    gem "better_errors" 
end 

/spec/spec_helper.rb是：

require "rubygems" 
require "database_cleaner" 
ENV["RAILS_ENV"] ||= "test" 
require File.expand_path("../../config/environment", __FILE__) 
require "rspec/rails" 
require "capybara/rspec" 
require "capybara/rails" 
require "capybara/dsl" 
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f} 
RSpec.configure do |config| 
    config.mock_with :rspec 
    config.fail_fast = true 
    config.fixture_path = "#{::Rails.root}/spec/fixtures" 
    config.before(:each) { ActionMailer::Base.deliveries.clear } 
    config.use_instantiated_fixtures = false 
    config.include(Capybara, :type => :integration) 
    config.use_transactional_fixtures = false 
    config.before(:suite) do 
    DatabaseCleaner.strategy = :deletion 
    DatabaseCleaner.clean_with(:truncation) 
    end 
    config.before(:each) do 
    DatabaseCleaner.start 
    end 
    config.after(:each) do 
    DatabaseCleaner.clean 
    end 
    config.after do 
    if example.metadata[:type] == :feature && example.exception.present? && page.current_path.present? 
     save_and_open_page 
    end 
    end 
end

我不認爲你需要包括你的控制器規範中的URL控制器。這裏是爲我工作的語法：

describe "POST my_action" do 
    it "blah blah" do 
    post :my_action, {:id => id, :x => x, :y => y} 
    ... 
    end 
end
