Rails 4.2.0 ActionController::UrlGenerationError

Question

我已经升级了rails 4.2.0和spree 3.0

一旦我运行 rspec，我就会收到以下错误，它向我显示 Rails 4.2.0 中的 rspec ActionController::UrlGenerationError，我在 google 上搜索了很多，但没有找到任何解决方案，请找到以下日志：

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

Answer 1

此错误是在 Spree 3.0 中引入的，该提交清理了 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 之外的路线Spree::Core::Engine.routes，但您spec_helper.rb仍然包含此行：

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

怎么修

选项1）

通过重新分配用于测试的路由来修复有问题的规范。例子：

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，或者 Spree 路由命名空间中的任何内容，您只需从项目的或中删除此行：spec/spec_helper.rbspec/rails_helper.rb

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

这是怎么发生的

• 以前，Spree 引擎路由是使用和use_route内部的参数指定的。它们不会干扰您自己的命名空间下的控制器测试。process_spree_actionprocess_spree_xhr_action
• Rails 4.2 已弃用use_route。
• Spree 已更改为较新的版本routes { Spree::Core::Engine.routes }，现在适用于包括Spree::TestingSupport::ControllerRequests.
• 这都是因为 Rspec 的引擎支持确实很差，所以社区一直在尽最大努力让这些工具协同工作。
