使用 rSpec 测试机架路由 [英] Testing Rack Routing Using rSpec

问题描述

我的 routes.rb 中有一条规则:

I have a rule in my routes.rb:

constraints AssetRestrictor do
  match '*seopath' => SeoDispatcher
end

然后在 lib/seo_dispatcher.rb 中，我有这个:

Then in lib/seo_dispatcher.rb, I have this:

class SeoDispatcher
  AD_KEY = "action_dispatch.request.path_parameters"

  def self.call(env)
    seopath = env[AD_KEY][:seopath]

    if seopath
      params = seopath.split('/')           # get array of path components
      env[AD_KEY][:id] = params.last        # the real page name is the last element
      env[AD_KEY][:category] = params.first if params.length > 1
    end

    Rails.logger.debug "routing to show #{env[AD_KEY]}"
    PagesController.action(:show).call(env)
    # TODO error handling for invalid paths
  end
end

class AssetRestrictor
  EXCEPTION_FILES = ['javascripts', 'stylesheets', 'autodiscover']
  def self.matches?(request)
    return false if request.method == 'POST'  # no post requests are SEO-ed
    EXCEPTION_FILES.each do |ex|
      return false if request.url.include?(ex)
    end
    true
  end
end

基本上，整个事情都奏效了.这个想法是剥离最后一个路径组件并将其与页面的 slug 匹配.搜索引擎优化人员告诉我，这是诱使搜索引擎将您排名更高的很酷的方法.

And basically, the whole thing works. The idea is to peel off the last path component and match it to the slug for a page. SEO people tell me this is the cool way to trick search engines into ranking you higher.

撇开我尖刻的评论不谈，我在 rSpec 中编写测试来执行此代码时遇到了麻烦.我的第一枪是:

My snarky comments aside, I'm having trouble writing a test in rSpec that exercises this code. My first shot at it was:

describe SeoDispatcher do
  it "routes /insurance/charters-and-guides/how-to-buy-charter-boat-insurance to pages#show :id => how-to-buy-charter-boat-insurance" do
    { :get => "/insurance/charters-and-guides/how-to-buy-charter-boat-insurance"}.should route_to(
      :controller => 'pages',
      :action     => 'show',
      :id         => 'how-to-buy-charter-boat-insurance'
    )
  end
end

但这根本不执行机架调度代码.有谁知道一个人将如何(而不是 cuking)练习代码?我真的很想从 Rack 中引入参数，而不是仅仅执行 SeoDispatcher.call({"action_dispatch.request.path_parameters" => {:seopath => "/foo/bar"}}).

But this simply doesn't exercise the Rack dispatch code. Does anyone know how one would (than cuking it) exercise the code? I really want to bring the parameters in from Rack instead of just doing SeoDispatcher.call({"action_dispatch.request.path_parameters" => {:seopath => "/foo/bar"}}).

谢谢！

推荐答案

好的，回答了我自己的问题.请求规范:

Ok, answered my own question. Request spec:

describe SeoDispatcher do
  describe "seo parsing" do
    it "GET /insurance/charters-and-guides/how-to-buy-charter-boat-insurance displays how-to-buy-charter-boat-insurance (3-part path)" do
      p = Page.make(:title => "how-to-buy-charter-boat-insurance")
      p.save
      get "/insurance/charters-and-guides/how-to-buy-charter-boat-insurance"
      request.path.should == "/insurance/charters-and-guides/how-to-buy-charter-boat-insurance"
      assigns[:page].slug.should == "how-to-buy-charter-boat-insurance"
    end

    it "GET /insurance/charters-and-guides displays guides (2-part path)" do
      p = Page.make(:title => "charters and guides")
      p.save
      get "/insurance/charters-and-guides"
      request.path.should == "/insurance/charters-and-guides"
      assigns[:page].slug.should == "charters-and-guides"
    end

    it "GET /insurance displays insurance (1-part path)" do
      p = Page.make(:title => "insurance")
      p.save
      get "/insurance"
      request.path.should == "/insurance"
      assigns[:page].slug.should == "insurance"
    end
  end
end
