ruby-on-rails - RSpec 找不到我的命名路线

Question

让我的命名路由在我的 rspec 测试中工作时遇到了莫名其妙的困难。

这是我所看到的:

1) Home GET / works!
 Failure/Error: get root_path
 NameError:
   undefined local variable or method `root_path' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1:0x007fe13b0c1538>
 # ./spec/requests/home_spec.rb:6:in `block (3 levels) in <top (required)>'

2) Home GET / shows products!
 Failure/Error: get products_path
 NameError:
   undefined local variable or method `products_path' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1:0x007fe13b0cdea0>
 # ./spec/requests/home_spec.rb:10:in `block (3 levels) in <top (required)>'

规范/请求/home_spec.rb

require 'spec_helper'

describe "Home" do
  describe "GET /" do
    it "works!" do
      get root_path
      response.status.should be(200)
    end
    it "shows products!" do
      get products_path
      response.status.should be(200)
    end
  end  
end

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 '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}

require 'spree/core/testing_support/factories'

RSpec.configure do |config|
  config.mock_with :rspec
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.use_transactional_fixtures = true
  config.infer_base_class_for_anonymous_controllers = false
  config.before(:suite) do
    # DatabaseCleaner.strategy = :truncation
  end
  config.before(:each) do
    # DatabaseCleaner.start
  end
  config.after(:each) do
    # DatabaseCleaner.clean
  end

  config.include Rails.application.routes.url_helpers
end

可以看到测试包含spec_helper，spec_helper 包含路由方法。这是我的佣金路线:

捆绑 exec rake 路由

...
             root        /                        spree/home#index
         products GET    /products(.:format)      spree/products#index
...

知道这里会发生什么来阻止路线工作吗？谢谢!

如果您想从虚拟应用程序中的测试中引用引擎的路由，或者只是应用程序本身，那么您需要在路由助手前加上引擎名称。对于 Spree，您可以引用以下路线:

spree.products_path

同样，如果要从引擎引用主应用程序的路由，则需要使用 main_app :

main_app.root_path
