Rspec找不到ActiveAdmin控制器

我正在尝试使用rspec测试ActiveAdmin中的自定义成员操作。

应用程序/管理员/非活动用户。rb型

ActiveAdmin.register InactiveUser do
  member_action :activate, method: :put do
    user = User.new(email: resource.email, password: generate_activation_code)
    resource.destroy if user.save
    send_activation_email user
    redirect_to admin_inactive_users_path, notice: "#{user.email} was activated"
  end
end

require 'spec_helper'

describe Admin::InactiveUserController do
  render_views

  before do
    @admin = FactoryGirl.create(:admin, confirmed_at: Date.yesterday)
    authenticate_user @admin
  end

  describe "PUT #activate" do
    before(:each) do
      @inactive_user = FactoryGirl.create(:inactive_user)
      put :activate, id: @inactive_user.id
    end

    it "should redirect to inactive users index" do
      expect(response).to redirect_to(admin_inactive_users_path)
    end
  end
end

我遇到了这个错误:

NameError:
  uninitialized constant Admin
# ./spec/admin/inactive_user_controller_spec.rb:3:in `<top (required)>'

我试过了 this 没有任何运气。

此外,如果你知道有任何项目使用rspec对这类事情进行测试,那将是非常棒的,文档没有说太多。

更新: 现在它正在运行 active_admin 测试后初始化: 加载时出错

NameError:
  uninitialized constant Admin
# ./spec/admin/inactive_user_controller_spec.rb:3:in `<top (required)>'
