rspec + capybara未定義的局部變量或方法

Question

#gemfile
...
gem 'rspec-rails'
gem 'capybara'

我已經根據官方文檔在spec_helper.rb中添加了要求'capybara / rails'。 我已經生成了一個測試：

$rails generate integration_test authentication_pages

我寫了一個測試：

#spec/features/authentication_pages_spec.rb
describe "Authentication" do
  subject { page }    
  describe "signin" do    
    before { visit new_user_session_path }    
    describe "with invalid information" do
      before { click_button "Sign in" }    
      it { should have_title('Sign in') }
    end
  end
end

運行測試我有一個錯誤：

$rspec spec/features/authentication_pages_spec.rb 
F

Failures:

  1) Authentication signin with invalid information 
     Failure/Error: before { visit new_user_session_path }
     NameError:
       undefined local variable or method `new_user_session_path' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1::Nested_1:0x000000010f9618>
     # ./spec/features/authentication_pages_spec.rb:6:in `block (3 levels) in <top (required)>'

Finished in 0.0007 seconds
1 example, 1 failure

Failed examples:

rspec ./spec/features/authentication_pages_spec.rb:11 # Authentication signin with invalid information

new_user_session_path是有效路徑，我在我的應用程序中使用了它並且有效。

我沒有解決方案，我尊重官方文檔。 你能幫助我嗎？

我發現了錯誤：在spec / features / authentication_pages_spec.rb中缺少要求'spec_helper'

正確的文件是這樣的：

#spec/features/authentication_pages_spec.rb
require 'spec_helper'
describe "Authentication" do
  subject { page }    
  describe "signin" do    
    before { visit new_user_session_path }    
    describe "with invalid information" do
      before { click_button "Sign in" }    
      it { should have_title('Sign in') }
    end
  end
end
