Rspec 2.7 在发出请求之前访问规范中的控制器会话

Question

我正在使用 Rspec 测试我的控制器，但在向路径发出请求之前，我似乎无法设置当前被测控制器的会话变量。 例如这有效：

  describe "GET /controller/path" do
    it "if not matching CRSF should display message" do
      get controller_path

      request.session[:state] = "12334"
    end
  end

这不起作用（我收到一条错误消息，说 session 不是 Nil 类的方法）：

      describe "GET /controller/path" do
        it "if not matching CRSF should display message" do
          request.session[:state] = "12334"
          get controller_path
        end
      end

有什么想法吗？

使用新版本的 RSpec 做得很好，看：

describe SessionController do
  # routes are mapped as:
  # match 'login' => 'session#create'
  # get 'logout' => 'session#destroy'

  describe "#create" do
    context "with valid credentials" do
      let :credentials do
        { :email => 'example@gmail.com', :password => 'secret' }
      end

      let :user do
        FactoryGirl.create(:user, credentials)
      end

      before :each do
        post '/login', credentials
      end

      it "creates a user session" do
        session[:user_id].should == user.id
      end
    end

    # ...
  end

  describe "#destroy" do
    context "when user logged in" do
      before :each do
        get "/logout", {}, { :user_id => 123 } # the first hash is params, second is session
      end

      it "destroys user session" do
        session[:user_id].should be_nil
      end

      # ...
    end
  end
end

您也可以在before(:each) 块内简单地使用request.session[:user_id] = 123，但上面看起来更漂亮。

试试这个：

describe "GET /controller/path" do
    it "if not matching CRSF should display message" do
      session[:state] = "12334"
      get controller_path
    end
  end
