RSpec 控制器规格不起作用，除非明确添加 ：type => ：控制器

Question

我试图运行$ rspec命令，但我所有的控制器测试都失败了，除非我明确地将:type => :controller添加到每个规格。

下面是我得到的错误:

1) AccountsController GET index assigns all accounts as @accounts
     Failure/Error: get :index, {}, valid_session
     NoMethodError:
       undefined method `get' for #<RSpec::ExampleGroups::AccountsController_2::GETIndex:0x007fd96c8a6a68>
     # ./spec/controllers/accounts_controller_spec.rb:36:in `block (3 levels) in <top (required)>'

生成的规范如下:

require 'spec_helper'
# This spec was generated by rspec-rails when you ran the scaffold generator.
# It demonstrates how one might use RSpec to specify the controller code that
# was generated by Rails when you ran the scaffold generator.
#
# It assumes that the implementation code is generated by the rails scaffold
# generator.  If you are using any extension libraries to generate different
# controller code, this generated spec may or may not pass.
#
# It only uses APIs available in rails and/or rspec-rails.  There are a number
# of tools you can use to make these specs even more expressive, but we're
# sticking to rails and rspec-rails APIs to keep things simple and stable.
#
# Compared to earlier versions of this generator, there is very limited use of
# stubs and message expectations in this spec.  Stubs are only used when there
# is no simpler way to get a handle on the object needed for the example.
# Message expectations are only used when there is no simpler way to specify
# that an instance is receiving a specific message.
describe AccountsController do
  # This should return the minimal set of attributes required to create a valid
  # Account. As you add validations to Account, be sure to
  # adjust the attributes here as well.
  let(:valid_attributes) { { "subdomain" => "MyString" } }
  # This should return the minimal set of values that should be in the session
  # in order to pass any filters (e.g. authentication) defined in
  # AccountsController. Be sure to keep this updated too.
  let(:valid_session) { {} }
  describe "GET index" do
    it "assigns all accounts as @accounts" do
      account = Account.create! valid_attributes
      get :index, {}, valid_session
      assigns(:accounts).should eq([account])
    end
  end
...

如果我查看spec/rails_helper。

# RSpec Rails can automatically mix in different behaviours to your tests
  # based on their file location, for example enabling you to call `get` and
  # `post` in specs under `spec/controllers`.
  #
  # You can disable this behaviour by removing the line below, and instead
  # explicitly tag your specs with their type, e.g.:
  #
  #     RSpec.describe UsersController, :type => :controller do
  #       # ...
  #     end
  #
  # The different available types are documented in the features, such as in
  # https://relishapp.com/rspec/rspec-rails/docs
  config.infer_spec_type_from_file_location!

但我是新的RSpec和TDD，我不确定如果这个rails_helper。

文件是否正在被读取。

规范/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 'email_spec'
require 'rspec/autorun'
# 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.include(EmailSpec::Helpers)
  config.include(EmailSpec::Matchers)
  # ## Mock Framework
  #
  # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
  #
  # config.mock_with :mocha
  # config.mock_with :flexmock
  # config.mock_with :rr
  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, remove the following line or assign false
  # instead of true.
  config.use_transactional_fixtures = true
  # If true, the base class of anonymous controllers will be inferred
  # automatically. This will be the default behavior in future versions of
  # rspec-rails.
  config.infer_base_class_for_anonymous_controllers = false
  # Run specs in random order to surface order dependencies. If you find an
  # order dependency and want to debug it, you can fix the order by providing
  # the seed, which is printed after each run.
  #     --seed 1234
  #config.order = "random"
  config.before(:suite) do
    DatabaseCleaner.strategy = :truncation
  end
  config.before(:each) do
    DatabaseCleaner.start
  end
  config.after(:each) do
    DatabaseCleaner.clean
  end
end

谁能告诉我，我怎么能得到我的控制器规格运行，而不必明确地添加:type => :controller ?控制器规格都在目录spec/controllers中，所以RSpec应该知道它们是控制器规格。

Answer 1

你运行的是RSpec 3，你还没有从RSpec 2完全升级你的配置

respect -rails 3生成'spec_helper '。'和'rails_helper.rb'。"rails_helper。'需要'spec_helper.rb'。在aspect - Rails 3中，Rails类的规范应该是require 'rails_helper'，而不是生成的规范所做的require 'spec_helper'。所以,要么

• change require 'spec_helper' to require 'rails_helper'，
• 重新生成脚手架(我相信你的规范是由respect -rails 2生成的)，或者
• 完全删除要求，并将--require rails_helper放在项目的.rspec文件中，以便它自动包含在所有规格中。

然后config.infer_spec_type_from_file_location!生效
