Ruby on rails Rails中管理面板指标的测试控制器

我有一个非常简单的管理面板，其中显示了总用户数、本周新用户数和本月新用户数。我想在我的控制器规范中为此编写一个测试。目前，我正在尝试获取要工作的用户总数。新的编码。谢谢

我得到了这个错误：

1) Admin::DashboardController metrics shows correct metrics for # of users
 Failure/Error: users = FactoryGirl.create_list([@user_1, @user_2, @user_3])
 ArgumentError:
   wrong number of arguments (1 for 2+)

仪表板\控制器\规格rb：

  describe 'metrics' do
    before :each do
      @user_1 = FactoryGirl.create(:user, created_at: Time.now)
      @user_2 = FactoryGirl.create(:user, created_at: Time.now - 1.week)
      @user_3 = FactoryGirl.create(:user, created_at: Time.now - 4.week)
    end

    it 'shows correct metrics for # of users' do
      users = FactoryGirl.create_list([@user_1, @user_2, @user_3])
      expect(assigns(:metrics[:users][:total])).to eq(users)
    end

    it 'shows correct number of new users this week' do
    end

    it 'shows correct number of new users this month' do
    end
  end

dashboard_controller.rb

class Admin::DashboardController < ApplicationController
  before_action :authorize_user!

  def index
    @metrics = {
      users: {
        total: User.count,
        this_week: User.where('created_at >= ?', 1.week.ago).count,
        this_month: User.where('created_at >= ?', 4.weeks.ago).count
      }
    }
  end
end

class Admin:：DashboardController=？'，1.week.ago）。计数，
本月：User.where（'created_at>=？'，4周前）。计数
}
}
结束
结束

我找到了答案：

describe 'metrics' do
  before :each do
    @user_1 = FactoryGirl.create(:user, created_at: Time.zone.now)
    @user_2 = FactoryGirl.create(:user, created_at: Time.zone.now - 1.week)
    @user_3 = FactoryGirl.create(:user, created_at: Time.zone.now - 4.weeks)
  end

it 'shows correct metrics for # of users' do
  expect do
    users = FactoryGirl.create_list([@user_1, @user_2, @user_3])
    assigns(:metrics).to eq(users)
  end
end

it 'shows correct number of new users this week' do
  expect do
    users = FactoryGirl.create_list([@user_1, @user_2, @user_3])
    assigns(:metrics[users][last_week]).to eq(users)
  end
end

it 'shows correct number of new users this month' do
  expect do
    users = FactoryGirl.create_list([@user_1, @user_2, @user_3])
    assigns(:metrics[users][last_month]).to eq(users)
  end
end
