调整嵌套路由的 rspec 路由测试

Question

在构建我的应用程序时，我生成了脚手架，它创建了标准的 Rspec 测试。我想使用这些测试进行覆盖，但由于嵌套路由，它们似乎失败了：

当我运行测试时，这是它的反馈：

Failures:

  1) ListItemsController routing routes to #index
     Failure/Error: get("/list_items").should route_to("list_items#index")
       No route matches "/list_items"
     # ./spec/routing/list_items_routing_spec.rb:7:in `block (3 levels) in <top (required)>'

Finished in 0.25616 seconds
1 example, 1 failure

如何告诉 Rspec 有嵌套路由？

以下是删节文件：

list_items_routing_spec.rb：

require "spec_helper"

describe ListItemsController do
  describe "routing" do

    it "routes to #index" do
      get("/list_items").should route_to("list_items#index")
    end

end

list_items_controller_spec.rb：

describe ListItemsController do
  # This should return the minimal set of attributes required to create a valid
  # ListItem. As you add validations to ListItem, be sure to
  # adjust the attributes here as well.
  let(:valid_attributes) { { "list_id" => "1", "project_id" => "1"  } }

  # 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
  # ListItemsController. Be sure to keep this updated too.
  let(:valid_session) { {} }

  describe "GET index" do
    it "assigns all list_items as @list_items" do
      list_item = ListItem.create! valid_attributes
      get :index, project_id: 2, {}, valid_session
      assigns(:list_items).should eq([list_item])
    end
  end

routes.rb:

  resources :projects do
    member do
      match "list_items"
    end
  end

注意事项： - 我尝试将 rpec 测试本身更改为包含 project_id，但这并没有帮助。 - 我正在使用 Factory Girl 生成夹具（不确定这是否相关）

感谢您的帮助！

首先，运行rake routes 以查看存在哪些路由。

根据您在路线中的内容，我希望您有一个ProjectsController，它有一个动作list_items。此操作将在/projects/:id/list_items 下可用。

现在我只能推测你真正想要什么，但我会猜测。

如果您希望 /projects/:project_id/list_items 路由到 list_items#index，您必须将您的路由更改为：

resources :projects do
    resources :list_items
end

您可以通过运行rake routes 来确认。

然后在您的路由规范中修复断言：

get("/projects/23/list_items").should route_to("list_items#index", :project_id => "23")

RSpec v2.14+ 预期更新

expect(:get => "/projects/23/list_items").to route_to("list_items#index", :project_id => "23")
