#<RSpec::Core::ExampleGroup::Nested_1::Nested_1:0x1057fd428>的未定义方法`sign_in'尝试使用 Devise 设置 RSpec 时出错 [英] undefined method `sign_in' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1:0x1057fd428> error while trying to set up RSpec with Devise

问题描述

我有一个spec/controllers/add_to_carts_spec.rb:

require 'spec_helper'

describe CartItemsController do

  before (:each) do
    @user = Factory(:user)
    sign_in @user
  end

  describe "add stuff to the cart" do
    it "should add a product to the cart" do
      product = FactoryGirl.create(:product)
      visit products_path(product)
      save_and_open_page
      click_on('cart_item_submit')
    end
  end

end

和/spec/support/spec_helper.rb:

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'capybara/rspec'

# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

RSpec.configure do |config|
  config.mock_with :rspec
  config.use_transactional_fixtures = true
end

... 它还加载 /spec/support/devise.rb:

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
end

Guard 在后台运行并不断抛出这个:

Guard is running in the background and keeps throwing this:

Failures:

  1) CartItemsController add stuff to the cart should add a product to the cart
     Failure/Error: sign_in @user
     NoMethodError:
       undefined method `sign_in' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1:0x1057fd428>
     # ./spec/controllers/add_to_carts_spec.rb:7

过去几个小时我尝试了各种配置调整和不同的语法，但似乎没有任何变化.有什么想法吗?

I've spent the last couple hours trying various config adjustments and different syntaxes but nothing seems to change. Any ideas?

推荐答案

那些测试助手不适用于集成/请求规范.在这些情况下测试 Devise 的推荐方法是访问登录页面，填写表单并提交，然后运行测试.

Those test helpers won't work for integration/request specs. The recommended way to test Devise in these situations is to visit the login page, fill in the form and submit it, and then run the test.
