Ruby on rails 如何为授权用户编写测试？

请帮忙指教

我为动作编辑编写了测试：

  setup do
    @user = users(:one)  
  end

  test "should get edit" do
    get :edit, id: @user
    assert_response :success
    assert_template :edit
    assert_template layout: "layouts/application"           
  end

users.yml：

one:
  name: 'onfge'
  email: 'MyStrdfing@ad.ad'
  password_digest: '$2a$10$XS2HLwMZxg/7yRKAWd9AJ.afCMra0wGWK4b.FhkY/qo3Lmo/tKEiO'
  remember_token: 'dc3461e13c8d316dad22332a503e06edafa0b9cb'
  phone: '43535345'
  skype: 'gggggg'
  gender: one
  info: 'MyString'
  admin: true
  avatar_file_name: nil
  avatar_content_type: nil
  avatar_file_size: nil

问题是页面

/users/2/edit

仅访问经过身份验证的用户。现在它被重定向到身份验证页面

请告诉我如何在测试中实现成功的身份验证？我试着做到以下几点：

test/test_helper.rb：

class ActiveSupport::TestCase
  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  fixtures :all

  # Add more helper methods to be used by all tests here...

  module SignInHelper
    def sign_in(user)
      session[:user_id] = user.id
    end
  end

  class ActionController::TestCase
    include SignInHelper
  end  
end

用户\控制器\测试.rb：

  test "should get edit" do
    sign_in(@user)
    get :edit, id: @user
    assert_response :success
    assert_template :edit
    assert_template layout: "layouts/application"           
  end

但进入控制台时出现以下错误消息：

rake test:controllers
  1) Failure:
UsersControllerTest#test_should_get_edit [/home/kalinin/rails/ZSUM/test/controllers/users_controller_test.rb:59]:
Expected response to be a <success>, but was <302>

您使用什么进行身份验证？你用的是Deviate吗？不是。我用的是自定义代码。你用什么进行身份验证？你用的是Deviate吗？不，我用的是自定义代码

  def create
    user  = User.find_by(email: params[:session][:email].downcase)
    if  user  &&  user.authenticate(params[:session][:password])
      sign_in user
      flash[:success] = "Welcome  to  the Sample  App!"
      redirect_to user
    else
      flash.now[:error] = 'Invalid  email/password  combination'  
      render  'new'
    end    
  end
