如何在rspec集成测试中访问rails请求对象？

在Rails 3.2.13中，默认提供子域。因此，我想测试我的应用程序，以便当商家注册时，他默认使用子域'商家'即root_url，即https://merchant.lvh.me:3000。但是，我在RSpec中测试相同的问题。我的测试看起来像这样：

  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: "user@gmail.com"
            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('user@gmail.com') }

                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('user@gmail.com') }

                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

错误是：

Done.

我试图打印请求对象以查看是否有任何内容，但它是空白的。如何在RSpec集成测试中访问请求对象或者是集成测试正确的地方来测试这种行为？请建议。

编辑：更多信息我的数据模型仅包含单个用户表，默认情况下，所有用户表均为普通用户。但是，有些人也是商人。现在，当某人以用户身份登录（使用登录表单中的单选按钮进行区分）时，应将其重定向到user.lvh.me，如果他以商家身份登录，则应将其重定向到merchant.lvh 。我。这就是我在集成测试中尝试测试的内容。

您可以使用

模拟请求 
ActionController::TestRequest.new()

例如

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

我不太清楚你在这里尝试测试的行为。

您似乎有一个注册表单，商家可以注册。一旦他们注册，他们应该获得自己的子域名（merchant1.lvh.me，merchant2.lvh.me）。是吗？

如果这是正确的，那么您似乎正在尝试测试应该设置注册请求的子域。我不认为这是如何工作的 - 客户端控制的域是请求不是服务器。我怀疑你想要做的是在成功注册到适当的subdomian后执行重定向。因此，您希望测试响应是否重定向到子域。
