尝试ActionDispatch :: Reloader

Question

我遇到了Spork测试服务器的问题。

如果我在config / environments / test.rb中设置config.cache_classes = false，那么规格就会开始出现rasie错误。

Failure/Error: task = Factory(:something, :foo => @foo, :bar => @bar)
     DataMapper::ImmutableError:
       Immutable resource cannot be modified

这是我的spec_helper.rb：

require 'spork'

Spork.prefork do
  if ENV['CODE_COVERAGE'] == '1'
    require 'simplecov'
    SimpleCov.start 'rails'
  end

  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'
  require 'webmock/rspec'
  require 'factory_girl'

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

  RSpec.configure do |config|
    config.mock_with :mocha
    config.include Rails.application.routes.url_helpers
    config.include UrlHelper

    config.before(:each) do
      repository(:default) do
        transaction = DataMapper::Transaction.new(repository)
        transaction.begin
        repository.adapter.push_transaction(transaction)
      end
    end

    config.after(:each) do
      repository(:default).adapter.pop_transaction.try(:rollback)
    end

  end
end

# This code will be run each time you run your specs.
Spork.each_run do
  # reload factories
  Factory.definition_file_paths = Dir[File.join(Rails.root, "spec", "factories")]
  Factory.find_definitions

  DatabaseCleaner.strategy = :truncation
  DatabaseCleaner.clean
  LoggedEvent.all.destroy!

end

当我有config.cache_classes = true时，一切都运行良好，但它没有重新加载模型，控制器类，所以在这种情况下我没有看到使用spork的重点。

当缓存为真时，我尝试添加到spec_helper.rb这样的东西：

Spork.each_run do
    Dir.glob("#{Rails.root}/app/models/*.rb").sort.each { |file| load file }
end

但我不喜欢这个解决方案。

Answer 1

只需添加：

ActiveSupport::Dependencies.clear

到prefork块的末尾。这将负责清理模型。

此外，您希望将rspec配置包含移动到Spork.each_run，同样需要规范支持和共享文件。

这很有效，我在2个项目中使用此设置，没有任何麻烦。

尝试ActionDispatch :: Reloader

除了在config.cache_classes = false中设置config/environments/test.rb之外，以下内容似乎使DataMapper和Spork在我们的团队中发挥出色：

Spork.each_run do

  # Routes
  MyApp::Application.reload_routes!

  if Spork.using_spork?
    # Reload all app files
    ActionDispatch::Reloader.cleanup!
    ActionDispatch::Reloader.prepare!

    # All factories
    FactoryGirl.reload
  end

end

您好，我想分享一下帮助我再次进行测试的原因事实证明，我必须添加shared_connection技巧，因为spork抱怨连接丢失在此之后，我不得不在块的末尾移动dependency.clear线，因为它正在缓存我的模型。

Spork.each_run do
  # ActiveSupport::Dependencies.clear # <-- moved this line at end of block as suggested by @solnic
  ActiveRecord::Base.instantiate_observers
  MyApp::Application.reload_routes!
  FactoryGirl.reload

  class ActiveRecord::Base
    mattr_accessor :shared_connection
    @@shared_connection = nil

    def self.connection
      @@shared_connection || retrieve_connection
    end
  end
  ActiveRecord::Base.shared_connection = ActiveRecord::Base.connection

  ActiveSupport::Dependencies.clear # <-- line moved here

end if Spork.using_spork?
