加载./spec/controllers/users_controller_spec.rb时发生错误

Question

我正在创建工厂来替换我的灯具并生成测试数据。我已经安装了FactoryBot但运行“rspec”时出错了。这是我得到的结果日志：

An error occurred while loading ./spec/controllers/users_controller_spec.rb.
Failure/Error: @user = FactoryBot.create(:user)

ActiveRecord::RecordInvalid:
  Validation failed: Email has already been taken
# ./spec/controllers/users_controller_spec.rb:5:in `block in <top (required)>'
# ./spec/controllers/users_controller_spec.rb:3:in `<top (required)>'


Finished in 0.00041 seconds (files took 38.38 seconds to load)
0 examples, 0 failures, 1 error occurred outside of examples

这是我的spec / factories / user_factory.rb

FactoryBot.define do
  factory :user do
    email "[email protected]"
    password "0123456"
    first_name "Peter"
    last_name "Example"
    admin false
  end
end

这是我的spec / controllers / users_controller_spec.rb

require 'rails_helper'

describe UsersController, type: :controller do

  @user = FactoryBot.create(:user)

  # let (:user) { User.create!(email:"[email protected]", password: "Ratadecierva2")}

  describe 'GET #show' do
      context 'when a user is logged in' do
        before do
          sign_in user
        end
        it 'loads correct user details' do
             get :show, params: { id: user.id }
             expect(response).to be_ok
             expect(assigns(:user)).to eq user
          end
        end

      context 'when a user is not logged in' do
        it 'redirects to login' do
          get :show, params: { id: user.id }
          expect(response).to redirect_to(new_user_session_path)
       end
    end
  end
end

错误意味着什么？我究竟做错了什么？

错误意味着什么？我究竟做错了什么？

您的工厂尝试使用与现有用户之一相同的电子邮件创建用户（难怪，看到电子邮件在工厂中是硬编码的）。您的数据库的唯一性约束抱怨。

您应该使用序列来处理用户电子邮件

# email "[email protected]"
sequence(:email) { |n|   "factory_#{n}@example.com" }

该工厂的第一位用户将收到电子邮件“[email protected]”，第二位 - “[email protected]”，依此类推。
