这是我的spec文件,当为上下文添加测试时“不是可单独更新用户余额”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
和工厂
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
在/spec/spec_helper.rb
我也有了这个
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user
Factory中的Sale
引用有关,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。有什么想法吗?
答案 0 :(得分:15)
在您的用户工厂中,请尝试以下方法:
factory :user do
email { Faker::Internet.email }
password "mypassword"
end
运行
factory(:user)
块 定义工厂时,而不是每次创建记录时。所以 如果Factory::Internet.email
第一次评估为foo@bar.com
, 然后工厂会尝试创建所有后续用户 那个电子邮件!)(根据@kristinalim,编辑语法)
