为什么专家在控制器测试中找不到策略？

Question

控制器:

class UsersController < ApplicationController
  def index
    ...
    authorize User
  end
  ...

政策:

class UserPolicy < ApplicationPolicy
  def index
    @user.admin?
  end
end

考试:

class UsersControllerAuthorizationTest < ActionController::TestCase
  tests :users

  def user
    @user ||= create(:user)
  end

  test 'should not authorize ordinary users to access the page' do
    sign_in user
    get :index
    assert_response :error
  end
end

该应用程序Pundit::NotAuthorizedError (not allowed to index? this User)按预期失败.但测试说:

Pundit::NotDefinedError: unable to find policy UserPolicy for User

我做错了吗？我可以让它找到政策吗？

UPD必须与rails'自动加载'有关.调用constantize上'UserPolicy'使得它自动加载app/policies/user_policy.rb的应用程序的情况下,并没有在测试的情况下.

UPD应该提出的问题spring.停止后,测试现在输出:

Pundit::NotAuthorizedError: not allowed to index? this User

为了解决这个问题,我跑了:

bin/spring stop
bin/spring binstub --remove --all
bundle update spring
bundle exec spring binstub --all
