Question

我的app/services文件夹中有一些服务。现在我想测试这些服务，所以我使用的是rspec和factorygirl。我正在使用factoryGirl创建用户，但是当我运行rspec时，它显示我跟随错误

 Failure/Error: @user ||= FactoryGirl.create(:user)

 ActiveRecord::RecordInvalid:
   Validation failed: Email has already been taken

我在每次测试后使用database_cleaner gem来清理数据库。以下是我的配置文件

ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
abort("The Rails environment is running in production mode!") if Rails.env.production?

require 'spec_helper'
require 'rspec/rails'
require 'factory_girl_rails'
require 'database_cleaner
ActiveRecord::Migration.maintain_test_schema!

RSpec.configure do |config|

  config.include FactoryGirl::Syntax::Methods

  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.include Devise::TestHelpers, type: :controller

  config.use_transactional_fixtures = false

  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


  config.infer_spec_type_from_file_location!
  config.filter_rails_from_backtrace!

end

我不知道我哪里出错了。

您需要指定在每个规范之间使用的策略（事务是一个安全的选择）：

RSpec.configure do |config|
  config.before(:suite) do
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:each) do
    DatabaseCleaner.strategy = :transaction
  end

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

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