rails 4.2.0 ActionController::UrlGenerationError

Question

我升级了rails4.2.0和spree 3.0

一旦我 运行 rspec 然后我得到以下错误，它显示 rspec ActionController::UrlGenerationError 在 rails 4.2.0 中，我有谷歌了很多但没有找到任何解决方案，请在下面找到日志：

Run options: include {:locations=>{"./spec/controllers/messages_controller_spec.rb"=>[10]}}

我的路线文件：

match 'messages/contact-us' => 'messages#contact_us', via: [:get]

rake 路由日志：

rake routes | grep "contact-us"

Answer 1

此错误由 this commit 在 Spree 3.0 中引入，它清理了 Spree 控制器测试指定要使用的路由的方式。您可能会看到此错误，因为您正在测试 Spree::Core::Engine.routes 之外的路由，但您的 spec_helper.rb 仍包含此行：

config.include Spree::TestingSupport::ControllerRequests, type: :controller

如何修复

选项 1)

通过重新分配用于测试的路由来仅修复有问题的规范。示例：

describe MessagesController, type: :controller do
  routes { Rails.application.routes }  # <--- add this line

  describe '#index' do
    before do
      get :index
    end

    specify do
      expect(response).to be_success
    end
  end
end

选项 2)

如果您的项目中没有任何命中 Spree 控制器的测试，或 Spree 路由命名空间中的任何内容，您可以简单地从项目的[=15]中删除这一行=] 或 spec/rails_helper.rb:

config.include Spree::TestingSupport::ControllerRequests, type: :controller

这是怎么发生的

• 以前，Spree 引擎路由是使用 process_spree_action 和 process_spree_xhr_action 内的 use_route 参数指定的。它们不会干扰您自己命名空间下的控制器测试。
• Rails 4.2 已弃用 use_route。
• Spree 更改为较新的 routes { Spree::Core::Engine.routes }，现在适用于包括 Spree::TestingSupport::ControllerRequests.
在内的所有内容
• 这都是因为 Rspec 有 admittedly poor Engine support，所以社区一直在尽最大努力让这些工具协同工作。
