这是我的规范文件,当为上下文添加测试时“不能作为可更新的用户余额”,我收到以下错误。

require 'spec_helper'

describe Sale do 

  context 'after_commit' do

    context 'assignable' do 
      sale = FactoryGirl.create(:sale, earned_cents: 10, assignable: true)
      after { sale.run_callbacks(:commit) }

      it 'updates user balance' do
        sale.user.balance.should == sale.earned
      end
    end

    context 'not assignable' do 
      sale = FactoryGirl.create(:sale, earned_cents: 10, assignable: false)
      after { sale.run_callbacks(:commit) }

      it 'does not updates user balance' do
        sale.user.balance.should_not == sale.earned
      end
    end

  end 
end

还有工厂

require 'faker'

FactoryGirl.define do
  factory :user do
    email Faker::Internet.email
    password "mypassword"
  end

FactoryGirl.define do
  factory :sale do
    earned_cents 5
    user
  end
end

/spec/spec_helper.rb也有这个

require 'database_cleaner'
RSpec.configure do |config|
  config.before(:suite) do
    DatabaseCleaner.strategy = :transaction
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:each) do
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end
end

这是我得到的错误。

`save!': Validation failed: Email has already been taken (ActiveRecord::RecordInvalid)

我猜它与Factoryuser内部的引用有关Sale,但我不知道为什么它没有为第二次测试生成新用户或从数据库中删除它。任何想法?

在您的用户工厂中,请尝试以下操作:

factory :user do
  email { Faker::Internet.email }
  password "mypassword"
end

为什么必须用大括号括起来:避免缓存值

factory(:user)块在定义工厂时运行,而不是在每次创建记录时运行。因此,如果第一次Factory::Internet.email评估foo@bar.com,那么工厂将尝试使用相同的电子邮件创建所有后续用户!)(根据@kristinalim,已编辑语法)
