Rails中管理面板指标的测试控制器

Question

我有一个非常简单的管理面板，其中显示了本周的总用户数，新用户数以及本月新用户数。我想在我的控制器规范中编写一个测试。目前我正在尝试让用户的总数工作。编码新手。谢谢！

我得到这个错误：

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+) 

dashboard_controller_spec.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

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
