Ruby on rails 如何在rails控制器中启用Desive helper方法？

我看过关于这个主题的其他帖子，我知道需要通过将design-helper方法添加到test\u-helper或spec\u-helper文件来启用design-helper方法，但这似乎不起作用

我还应该看什么来解决这个问题

我的rspec erro

Failures:

  1) LunchersController GET root renders index view for non-logged in users
     Failure/Error: get :index, {}
     NoMethodError:
       Could not render layout: undefined method `authenticate' for nil:NilClass
     # ./spec/controllers/lunchers_controller_spec.rb:6:in `block (3 levels) in <top (required)>'

我没有测试/但我已经创建了一个，并添加了一个测试帮助器，以查看是否包含以下帮助，但它没有

class ActionController::TestCase
  include Devise::TestHelpers
end

您是否尝试过在

spec/support

文件夹中创建一个文件（比如designe.rb），其中包含您为spec\u helper提到的内容？@AlexP在控制器测试中不起作用

sign\u in

方法？假设你创建了一个带有

factory\u girl

的用户，然后

登录（@user）

。我在这一个上选择了核选项，并将Desive降级为3.0.0，到目前为止一切似乎都正常。
