如何从Rails集成测试中访问会话？

Question

考虑以下集成测试:

test "if there is no user in session, redirect to index and flash message" do
  open_session do |sess|
    post '/login', :email => users(:client).email, :password => 'rumpelstiltskin'
    sess[:user] = nil
    get '/user_page'
    assert_redirected_to index_path
    assert_equal "Your session has expired. Please log in again", flash[:notice]
  end    
end

这会产生错误: undefined method '[]='

并且,更改以sess.session[:user] = nil生成错误:NoMethodError: undefined method 'session' for nil:NilClass

如何从Rails中的集成测试修改会话参数？

使用Rails 3.0.7,Ruby 1.9.2p180,单元测试框架.

编辑:
get '/user_page', nil, {:user => nil}并get ('/user_page', nil, {:user => nil} )生成错误.

Answer 1

在 Rails 3.2.3 中，以下内容似乎对我有用：

# Hit the root_path to start our session
get root_path

# A helper method to set our session
login_as(@user_fixture)

# Now we can access the session variable
assert session[:user_id]

不确定这是否适合你，祝你好运！

Answer 2

直接使用session[:user]，不open_session阻塞
