使用rspec和factory girl时出现了重复的工厂错误？

Question

我正在尝试在每次运行测试时重置Factory Girl中的“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。我在spec_helper.rb的最后几行中执行此操作。

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，出现以下错误。

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

这似乎是一个重复的工厂错误，可能正在尝试加载两次factory girl，但我不明白为什么会这样。

它试图加载你的所有工厂两次，因为你要求它这样做。将你对 find_definitions 的调用替换为：

FactoryGirl.reload

这将清除现有的工厂、序列等，然后为您调用find_definitions
