无法在Rails 5控制器测试中设置会话哈希

Question

根据Rails Edge指南,所有ActionDispatch :: IntegrationTest HTTP请求都带有可选的命名关键字参数:

get post_url, params: { id: 12 }, session: { user_id: 5 }

大.现在,我在控制器测试中得到以下代码:

test 'should redirect from login page if user is logged in' do
  get '/login', session: { user_id: users(:stephen).id }
  assert_redirected_to root_url, 'Expected redirect to root'
end

当我运行它时,我的测试失败,我看到以下弃用警告:

ActionDispatch::IntegrationTest HTTP request methods will accept only
the following keyword arguments in future Rails versions:
params, headers, env, xhr

所以显然它的rails不允许我传递一个名为session的关键字参数.

此外,在功能测试中设置会话的两种旧方法都不再有效:

test "some thing" do
  session[:user_id] = users(:stephen).id
  # etc
end

NoMethodError:nil的未定义方法`session':NilClass

这也失败了:

test "some thing" do
  get '/login', nil, nil, { user_id: users(:stephen).id }
  # etc
end

只会忽略会话哈希,并且会显示有关仅接受4个不同命名参数的rails的弃用警告.

有没有其他人在使用Rails 5.rc1时遇到这种麻烦？

在Rails 5中,不再可能在控制器测试中访问会话:http://blog.napcs.com/2016/07/03/upgrading-rails-5-controller-tests/.建议是访问为您设置适当会话值的控制器方法.此评论显示了您如何解决此限制的示例:https://github.com/rails/rails/issues/23386#issuecomment-192954569

  # helper method
  def sign_in_as(name)
    post login_url, params: { sig: users(name).perishable_signature )
  end

class SomeControllerTest
  setup { sign_in_as 'david' }

  test 'the truth' do
  ..
