加载 ./spec/controllers/users_controller_spec.rb 时出错

Question

我正在创建工厂来替换我的固定装置并生成测试数据。我已经安装了 FactoryBot，但在运行 "rspec" 时出现错误。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 "peter@example.com"
    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:"achochaocierva@gmail.com", 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

错误是什么意思？我做错了什么？

Answer 1

What would be the errors meaning? What am I doing wrong?

你的工厂试图创建一个用户，使用与现有用户之一相同的电子邮件地址（难怪，看到电子邮件地址在工厂中是硬编码的）。您的数据库的唯一性约束抱怨。

您应该为用户电子邮件使用序列

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

该工厂的第一位用户将收到电子邮件 "factory_1@example.com"，第二位 - "factory_2@example.com"，依此类推。
