如何訪問rspec集成測試中的rails請求對象？

在Rails 3.2.13中，默認提供子域。因此，我想測試我的應用程序，以便當商家註冊時，他默認默認爲root_url，子域「商家」即https://merchant.lvh.me:3000。但是，我在RSpec中測試相同的麻煩。我的測試是這樣的：如何訪問rspec集成測試中的rails請求對象？

describe "Sign in" do 
    before { visit signup_path } 
    let(:submit) { "Sign up" } 

    describe "with invalid information" do 
     it "should not create a user" do 
      expect { click_button submit }.not_to change(User, :count) 
     end 
    end 

    describe "with valid information" do 
     before do 
      fill_in "Email", with: "[email protected]" 
      fill_in "Password", with: "securepassword" 
     end 

     describe "as a merchant" do 
      before { choose("Merchant") } 

      it "should create a merchant user" do 
       expect { click_button submit }.to change(User, :count).by(1) 
      end 

      describe "after creating the merchant user" do 
       before do 
      click_button submit 
      request = ActionController::TestRequest.new(:host => "lvh.me:3000") 
     end 
       let(:merchant) { User.find_by_email('[email protected]') } 

       expect (request.subdomain).to eq('merchant') 
       it { should have_selector 'div.alert.alert-success', text: "Welcome to App!" } 
       it { should have_link "Sign out", href: signout_path } 
       it { should_not have_link "Sign in", href: signin_path } 
       it { should have_content merchant.email } 
      it { should have_selector "title", text: full_title(merchant.email) } 
      end 
     end 

     describe "as a user" do 
      before do 
      choose("User") 
      request = ActionController::TestRequest.new(:host => "lvh.me:3000") 
     end 

      it "should create a normal user" do 
       expect { click_button submit }.to change(User, :count).by(1) 
      end 

      describe "after creating the normal user" do 
       before { click_button submit } 
       let(:user) { User.find_by_email('[email protected]') } 

       expect (request.subdomain).to eq('user') 
       it { should have_selector 'div.alert.alert-success', text: "Welcome to App!" } 
       it { should have_link "Sign out", href: signout_path } 
       it { should_not have_link "Sign in", href: signin_path } 
      it { should have_content user.email } 
      it { should have_selector "title", text: full_title(user.email) } 
      end 
     end 
    end 
    end

我試圖打印請求對象，檢查是否有是有的，但它的空白。如何在RSpec集成測試中訪問請求對象或者是集成測試是否適合測試這種行爲？請建議。

編輯：更多信息我的數據模型只包含單個用戶表，其中默認情況下都是普通用戶。不過，也有一些商家。現在，當某人以用戶身份登錄（使用登錄表單中的單選按鈕進行區分）時，他應該重定向到user.lvh.me，如果他以商家身份登錄，則應將其重定向到merchant.lvh 。我。這就是我在集成測試中要測試的內容。

可以使用

ActionController::TestRequest.new()

例如

request = ActionController::TestRequest.new(:host => test_domain)

嗨，我按照你的建議，但仍然得到相同的錯誤。請參閱我已經包含在問題本身中的日誌。 – shailesh 2013-04-23 14:34:02

因爲我沒有看到更多的答案來臨，這是最接近的人去了，我接受它。但是如果有人能夠更好地解釋爲什麼我無法在集成測試中獲得請求，那麼可以接受。 – shailesh 2013-04-25 06:41:40

爲我完美工作，感謝發佈 – 2014-06-13 06:55:31

我真不明白你正試圖在這裏測試什麼行爲嘲笑的請求。

看起來你有註冊表單，商家可以註冊。一旦他們註冊，他們應該得到自己的子域（merchant1.lvh.me，merchant2.lvh.me）。是對的嗎？

如果這是正確的，那麼它看起來像你試圖測試應註冊請求的子域。我不認爲它是如何工作的 - 客戶端控制着請求發送給服務器的域。我懷疑你想要做的是在成功註冊適當的小數位後執行重定向。因此，您要測試響應正在重定向到子域。

嗨@Perryn福勒，我已經更新了這個問題。其實有兩類用戶 - 用戶和商家。如果某人以用戶身份登錄，則應將其重定向到user.lvh.me，如果他以商家身份登錄（在登錄表單中使用單選按鈕進行區分），則應將其重定向到merchant.lvh.me 。這就是我在集成測試中要測試的內容。 – shailesh 2013-04-23 14:21:34
