使用 RSPEC 测试依赖于环境的路由

Question

我有一些应该只存在于开发环境中的路线，但我无法获得这项工作的规范。知道我做错了什么吗？我最初在控制器规范中尝试过这个，但后来意识到我需要 :type => :routing 才能使用 be_routable 所以把它分开了。我已经调试并且 Rails.env 具有我在每个上下文中期望的值。我需要重新加载路线吗？已尝试这样做，但找不到 rspec 满意的语法...

来自 routes.rb 的片段：

    resources :users do
        collection do
          ...
          if Rails.env.development?
            get :new_development_account
            post :create_development_account
          end
        end
        ...

路由规范：

require 'spec_helper'

describe "routes for users controller", :type => :routing do

    context "production environment" do
      it "development routes do not exist" do
        allow(Rails).to receive(:env) { "production".inquiry }
        expect(:get => "/ims/users/new_development_account").not_to be_routable
        expect(:post => "/ims/users/create_development_account").not_to be_routable
      end
    end

    context "development environment" do
      it "development routes exist" do
        allow(Rails).to receive(:env) { "development".inquiry }
        expect(:get => "/ims/users/new_development_account").to be_routable
        expect(:post => "/ims/users/create_development_account").to be_routable
      end
    end
end

特别奇怪的是它没有通过两个测试：

Failures:

  1) routes for users controller production environment development routes do not exist
     Failure/Error: expect(:get => "/ims/users/new_development_account").not_to be_routable
       expected {:get=>"/ims/users/new_development_account"} not to be routable, but it routes to {:action=>"show", :controller=>"ims/users", :id=>"new_development_account"}

     # ./spec/support/database_cleaner.rb:18:in `block (2 levels) in <top (required)>'

  2) routes for users controller development environment development routes exist
     Failure/Error: expect(:post => "/ims/users/create_development_account").to be_routable
       expected {:post=>"/ims/users/create_development_account"} to be routable

Answer 1

路由在应用程序启动时加载一次，Rails.env 将是 'test'。

通常最好让您的开发环境尽可能接近生产环境，包括路由。

如果你想在开发环境中使用一些快捷方式，可以选择：

您可以使用常规 /ims/users/new 和 create 操作以及仅在开发中有效的参数。例如 /ims/users/new?development=true 也会呈现额外的隐藏字段以将状态传递给 create
对路由使用动态约束（这样路由仍会在 production/test 中列出，但无法访问）
保持路由始终存在，并在控制器中针对错误的环境引发错误
将整个 development_account-feature 提取到引擎中，单独测试并仅在开发中安装它（最难的方法，并非总是可行）

我会选择第一个选项，它既简单，封装得相对较好，而且很可能您的 *_development_account 无论如何都会模仿相应的操作

Answer 2

可以使用 Rails.application.reload_routes! 重新加载路线。

示例：

it "does not have routes in production" do
  allow(Rails).to receive(:env) { "production".inquiry }
  Rails.application.reload_routes!
  expect(:get => "/ims/users/new_development_account").not_to be_routable
  expect(:post => "/ims/users/create_development_account").not_to be_routable
end
