【问题描述】：

我正在尝试在我运行的每个测试之间重置工厂女孩的“序列”。

（factory_girl 2.6.0 和 factory_girl_rails 1.7.0）

我认为要这样做，我必须重新加载 FactoryGirl 定义。我是在 spec_helper.rb 的最后几行做的：

require 'rubygems'
require 'spork'
#uncomment the following line to use spork with the debugger
#require 'spork/ext/ruby-debug'

Spork.prefork do
  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'
  require 'rspec/autorun'
  require 'capybara/rspec'

  require "rails/application"
  Spork.trap_method(Rails::Application::RoutesReloader, :reload!)

  Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

  RSpec.configure do |config|
    config.mock_with :rspec

    require 'database_cleaner'
    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_base_class_for_anonymous_controllers = false

    # For mailer
    config.include(MailerMacros)
    config.before(:each) {reset_email}
  end

end

Spork.each_run do
  # This code will be run each time you run your specs.
  I18n.backend.reload!
  Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }
  require 'factory_girl'
  FactoryGirl.definition_file_paths = [File.join(Rails.root, 'spec', 'factories')]
  FactoryGirl.find_definitions
end

添加：

  FactoryGirl.definition_file_paths = [File.join(Rails.root, 'spec', 'factories')]
  FactoryGirl.find_definitions

运行rspec spec/时导致我出现以下错误

→ bundle exec guard
Guard uses Growl to send notifications.
Guard is now watching at '/Rails/projects/MyRailsProject'
Starting Spork for RSpec

Preloading Rails environment
Loading Spork.prefork block...
Spork is ready and listening on 8989!
Spork server for RSpec successfully started
Guard::RSpec is running, with RSpec 2!
Running all specs
Exception encountered: #<FactoryGirl::DuplicateDefinitionError: Factory already registered: user>

这似乎是一个重复的工厂错误，也许它试图加载工厂女孩两次，但我不明白为什么。

【解决方案1】：

它试图加载你所有的工厂两次，因为你要求它。将您对find_definitions 的呼叫替换为

FactoryGirl.reload

清除现有工厂、序列等，然后为您调用find_definitions
