路由规范是否支持重定向路由？[RSpec的]

Question

在深入研究这个问题之后,我在理解文档和结果之间陷入了僵局.

根据https://www.relishapp.com/rspec/rspec-rails/v/2-8/docs/routing-specs/route-to-matcher,我们应该能够编写以下内容:

#rspec-rails (2.8.1)
#rspec (>= 1.3.1)
#rspec-core (~> 2.8.0)

# routing spec
require "spec_helper"

describe BusinessUsersController do
  describe "routing" do
    it "routes to some external url" do
      get("/business_users/7/external_url").should route_to("http://www.google.com")
    end
  end
end

# routes.rb
BizeebeeBilling::Application.routes.draw do

  resources :business_users do
    member do
      get "external_url" => redirect("http://www.google.com")
    end
  end
end

运行此规范会产生以下结果:失败:

  1) BusinessUsersController routing routes to some external url
     Failure/Error: assert_routing "/business_users/7/external_url", "http://www.google.com"
     ActionController::RoutingError:
       No route matches "/business_users/7/external_url"
     # ./spec/routing/business_users_routing_spec.rb:19:in `block (3 levels) in <top (required)>'

我无法在任何地方找到报告此特定问题的人.

添加细节:手动测试时,路线得到很好的解决.

Answer 1

路由规范/测试专门用于测试路由是否映射到特定控制器和操作(也可能是某些参数).

我挖了一下Rails和Journey的内部结构.RSpec和Rails(基本上,遗漏了一些细节)Rails.application.routes.recognize_path用来回答"这是可路由的吗？"的问题.

例如:

$ rails console
> Rails.application.routes.recognize_path("/business_users/1", method: "GET")
 => {:action=>"show", :controller=>"business_users", :id=>"1"}

但是,另一端没有控制器/business_users/1/external_url.实际上,为了执行重定向,Rails创建了一个实例ActionDispatch::Routing::Redirect,它是一个小型的Rack应用程序.没有触及任何Rails控制器.您基本上安装了另一个Rack应用程序来执行重定向.

要测试重定向,我建议使用请求规范(文件输入spec/requests).就像是:

require "spec_helper"

describe "external redirection" do
  it "redirects to google.com" do
    get "/business_users/1/external_url"
    response.should redirect_to("http://www.google.com")
  end
end

这会隐式测试路由,并允许您测试重定向.

安迪林德曼有正确的答案.但是,您不必将规范放在规范/请求中,您可以将其保留在规范/路由中,并使用元数据"type"显式:describe 'my route', type: :request do

Answer 3

我遇到了类似的情况,我试图测试一系列路线,一些应该重定向,一些不应该.我想将它们保存在单个路由规范中,因为这是对它们进行分组的最合理方式.

我试过用describe: 'my route', type: request,但发现不行.但是,您可以RSpec::Rails::RequestExampleGroup在规范上下文中包含访问请求规范方法的权限.就像是:

describe "My Routes" do
  context "Don't Redirect" do
    it "gets URL that doesn't redirect" do
      get("business_users/internal_url").should route_to(controller: "business_users", action: "internal_url_action")
    end
  end

  context "Redirection" do
    include RSpec::Rails::RequestExampleGroup
    it "redirects to google.com" do
      get "/business_users/1/external_url"
      response.should redirect_to("http://www.google.com")
    end
  end
end
