Question

我有一个Rails应用程序，可以在其路由上安装另一个引擎，并且还会覆盖引擎中的某些路由。这是routes.rb：

Spree::Core::Engine.routes.draw do
  # some other routes
  root :to => "home#index"
end

MyNamespace::Application.routes.draw do
  class CityConstraint
    def matches?(request)
      Spree::CityZone.where(:url => request.params[:city_name]).exists?
    end
  end
  mount Spree::Core::Engine, :at => ':city_name/', :constraints => CityConstraint.new, :as => :city
  mount Spree::Core::Engine, :at => '/'
end

当我尝试使用RSpec（2.14）测试路线时，我总是会收到以下错误：

#encoding: utf-8
require 'spec_helper'

RSpec.describe "routes.rb" do
  it "test routing" do
    expect(get: "/").to route_to(controller: "spree/home", action: "index")
  end
end

 Failure/Error: expect(get: "/").to route_to(controller: "home", action: "index")
   No route matches "/"
 # ./spec/routing/routes_spec.rb:6:in `block (2 levels) in <top (required)>'

我发现，当我添加以下行时，它可以工作：

RSpec.describe "routes.rb" do
  routes { Spree::Core::Engine.routes } # this sets the routes
  it "test routing" do
    expect(get: "/").to route_to(controller: "spree/home", action: "index")
  end
end

问题是，我想测试整个应用，因为我们在城市名称范围（例如/your_city）和根/下安装了应用两次。

当我尝试在测试中设置routes { MyNamespace::Application.routes }时，我收到No route matches "/"错误。

有关如何测试整个已安装路线堆栈的想法，包括来自引擎的路线？

您可以尝试手动添加所需的路线：

RSpec.describe "routes.rb" do
  before :all do
    engine_routes = Proc.new do
      mount Spree::Core::Engine, 
            :at => ':city_name/', 
            :constraints => CityConstraint.new, 
            :as => :city
      mount Spree::Core::Engine, :at => '/'
    end
    Rails.application.routes.send :eval_block, engine_routes
  end

  it "test routing" do
    expect(get: "/").to route_to(controller: "spree/home", action: "index")
  end
end
